The World God Only Knows/WMG

Jossed or confirmed guesses are in their own folder at the end of the list (spoilers are unavoidable there, so open it at your own risk).

Kaminomi will have a Bittersweet Ending ... or not?
Keima manages to find Diana's sisters, and together they kick whoever released the seal's ass. Then the goddesses can return to Zeus, wherever he is. The contract between Keima and Elsee is finally lifted... And then Hell decides to erase Keima's memory, making him think everything happened in his games. We have seen it happen elsewhere, don't underestimate the author's cruelty.

But then, there are a couple of devils who would not take it well. Elsee will not leave his nii-san, so her chief manages to alter Keima's father memory. Elsee continues to live with Keima as his step sister.

Then one day some scythe-wielding Tsundere manages to draw up enough courage to corner Keima and confess to him.


 * Well, I think forementioned Bittersweet Ending applies to KeimaXElsee fans only. In fact, it's a thing to cheer for for KeimaXTenri fans.
 * What's not bittersweet about the guy losing all of his memories? I personally find that to be rather reprehensible.
 * He might lose his memories but still retain whatever Character Development he had, hence becoming a generally more likeable person. I don't think it's that bad. :3 But, yeah, the ending would be better, in my opinion, if he retains his memories.

One of the girls that Keima will have to help will be a hardcore otaku of the Gal Girl genre
She will also be a huge fan of the Capturing God, and the hole in her heart will be caused by her loneliness. So he has to lead her away from Gal Games. The whole thing also makes him reevaluate himself as well, and character development ensues.
 * Somewhat confirmed in the novels with

Keima's Mom will get possessed because of her worries about her husbands unfaithfulness.
Keima cannot or will not be able to save her. THEN his father shows up, does something incredible heart warming and poof. The day is saved.

Chihiro will become an enemy.
As a Woman Scorned, there is a large (enough) possibility that Vintage will manipulate Chihiro into working with them, using her broken heart to their favor. She's a major character who shows no signs of being Demoted to Extra. If that actually happens, she might house a strong Runaway Spirit and become really problematic. Remember the thing with Hinoki, the giant girl, Level 4 Runaway Spirit, Kusunoki's sister? It took all of the new devils from the surrounding districts to deal with her, and even then it took Nikaido, Keima's teacher, to deal with it. That was foreshadowing. There's no way they aren't going to use that again.

Nikaido is Elsee's older sister.
Elsee can't recognize her because of the 300 year separation, and Elsee is kinda dumb, or because Nikaido has changed her appearance. Nikaido either cannot recognize her, or is hiding her identity for Elsee's own safety.
 * Two pieces of evidence point against this: firstly, Nikaido was in the basketball team with Jun back when they were in school together and wasn't wearing a collar back then . If she was also in the Spirit Retrieval Squad and lived up to her reputation, it wouldn't make any sense for her not to have a partner at that time. Secondly, when Nikaido teased Akari/Rimuyel about Keima, Akari stated that she was the source of Nikaido's power. Unless this troper is completely mistaken, the buddy is there only for drawing out the spirit but doesn't actually provide any power behind the spirit capture.

Nanaka will recognize Keima's playing style.
The next time the two meet again (maybe when Keima visits Tenri's school or vice versa) there will be a Shogi tournament in said school. Naturally Nanaka would be playing. In a nostalgic move Keima decides to join too, just to see how much Nanaka has improved. BAD MOVE. Nanaka may have forgotten Keima as a person, but its harder to erase stuff like instinct and playing style. She'll have the nagging feeling she recognizes him, and when Keima tries to lose on purpose she'll object, demanding why he did that, instinctively feeling he could have won if he wanted too.

Mio will recognize Keima based on his dancing style
Just like with the Nanaka example above, something important to her capture will help trigger a return of her memories.

The devil girl with the glasses that released the big weiss will join the harem.
I took one look at her and thought "She's too cute NOT to join the main cast."
 * At this point, that's going to be very awkward.
 * She does look like the typical character who tries hard to get recognized in the evil organization, then realizes that they've been just using her as disposable goods and pulls a Heel Face Turn.
 * At last, Keima even asked to keep her. Knowing the guy, it's fair enough to guess he'll somehow seduce her to squeeze out some more info. Or maybe she'll be moved by his dedication and how such a man can't be wrong...

Kanon will join the girls music band
There know each other and most of the girls in the band have been captured by Keima (except Elsee). I'll also dare to say the other girl in the band will have a runaway spirit.

Rimyuel/Kurakawa Akari is Elsea's older sister

 * She's clearly not human; not stated to be a new devil, but most likely is one;
 * She didn't meet Elsea out of coincidence, this will lead to a "What, that is your sister?!?" moment for Keima later;
 * She's shorter than Elsee.
 * She likes Keima.
 * Both have a similar type of hair and they are two of the few left-handed characters in the series.

Keima's dad is Austin Powers!
Think about it, that both wear the cravat suits, wear glasses and attract the ladies. Why do you think Keima's mother easily believe Elsee's story about she being Keima's half sister?

Keima's dad is also working for Hell
Keima's dad spends a ton of time away from home. It's entirely possible that he's travelling around looking for them. Also it's a good reveal to use later, being easily lampshade-able.

Chihiro does not have a goddess, but will become more involved in the plot anyway.
She'll find out about the mindwipe, and after reading Keima the riot act, she'll find out about the Vintage thing. "What's that you say? Evil demons are threatening our way of life? I'm IN!"
 * Chihiro not having a goddess has been . The other point is still up in the air.

Elsea is the last capture target.
The last "mission" will involve the organizer of the runaway spirits possessing Elsea and forcing Keima to try to romance her.

Keima is host of a goddess.
A runaway spirits targets only girls because they want to reincarnate as their first born child, but the goddess are just hidding, so they shouldn't have such limitation. There is very little evidence to support this theory, maybe just two things: Keima was next to Tenri when she became the host of Diana and it makes little sense to me that a demon's partner can see the supernatural (Haqua's partner didn't show any reaction to the runaway spirit possessing that girl in FLAG 49). Anyway, just think about it... wouldn't it be awesome to see how he capture himself?.
 * Vulcan / Haepestus fits pretty nicely. He's Ugly Cute, quite the Chick Magnet despite it, thechologically inclined, surrounds himself with Artificial Humans, and he's the father of Cupid / Eros.
 * The last point is Jossed as of Chapter 133.

Elsie has a Perverse Sexual Lust for Optimus Prime.
Or whatever the Bland-Name Product equivelent is. She watches cartoons, and Optimus Prime is the closest way to marry a fire truck.

There is another side effect for using love to draw out runaway spirits.
Keima's is the only person to use love, right? Since it's never been really documented, it's possible that there's some other effect it has on the girls beyond helping them with their issues. "'Haqua': No one tries it because it's so unstable. If they fail, the gap widens. And it's easy for the gap to reopen as well."
 * The reason:


 * She then questions him how did he avoid all the problems associated with the method, to which he's unable to answer. In my opinion, the reason why it works so well for Keima is because he isn't just merely making them to fall in love with him, but also solves whatever emotional problems they're having in the process (which is why they fall in love with him anyhow). But that makes the process more difficult, and perhaps Keima's the only one who can really pull it off. That's why it's not an efficient method to use, comparing to Nora's or Yukie's method for example.
 * I'm afraid I'll have to disagree on his method being inefficient. They kind of made this whole big thing out of the fact that Keima and Elsee are absolutely crushing all the other demons at capturing spirits.
 * What I meant was that it was an inefficient method to others, not to our Keima.

Keima might be somehow related to
This would explain his god-like status and why the goddesses are flocked towards him.
 * Or...
 * Or...
 * Or...
 * Or...

Keima is

 * The new arc is going to be called . It seems obvious that all the goddesses want their hosts  . So, maybe the new arc will be about the goddesses trying to get the 'heart' of Keima. Then again, that would be a pretty sucky arc...

Keima will be a professional gambler as an adult

 * What could be a better job for the God of Games? He's shown he's good at all games, not just video games.

One of the goddesses won't be joining Keima's harem.
The foreshadowing image from chapter 1 only shows 5. Whether this means Kanon dies or one of the goddesses just refuses to cooperate, we'll find out eventually. Though, admittedly, the author could have just originally planned for 5 and added one later.

One of the Goddesses will be captured by Haqua
http://www.mangafox.com/manga/the_world_god_only_knows/v15/c139/19.html Foreshadowing anyone?
 * But how would that work? Would they trick Yui into thinking she was a dude in disguise or something?

Puella Magi Madoka Magica spoilers:

Dokuro Skull is an
In the kaminomi world, the Weiss are the way of harvesting energy out of. Capturing them when then the weiss have possessed the girls is how, the higher level the weiss,. The Runaway Spirit Squad can be compared to the Puella Magi.

Elsie's sister is a member of vintage.
Would make for a neat twist, considering how Elsie fondly alludes to her.
 * Not just a member, but the leader. Or one of the higher-ups, at any rate. Since she's supposed to be really skilled and all.

However briefly, Elsie's curse turned Jupiter into a frog.
She cursed "kami-sama". Keima didn't end up becoming a frog, but why not the real god of the TWGOK universe? It seems that Jupiter is being referred to as te leader of Heaven, so that would make the most sense, although they'd need to explain how exactly Jupiter wasn't too strong to shrug it off. But it would be funny.

Chihiro will marry Keima.
Considering how much of the story seems to be getting alluded to in the omakes, I can't exactly let this one slide.


 * As of chapter 166, this WMG just got a serious shot in the arm. As it turns out,.

Keima really is a god, or something similar
Really it is a shonen show, who wouldn't see this comming? Plus you try playing 24 games at once and see what happens.

Maijima, specifically the school, is an area on Earth where Heaven and Hell intersect.
Even Keima thinks that there might be something special with the city in (manga) FLAG 131.
 * In FLAG 160, the Vintage members who were interrogating Haqua mentioned something about a "Singularity" when they are talking about her Vintage replacement.

Vintage caused the Great Runaway Spirit Escape that happened 10 years before the story began.
While they were undoing the seal, they inadvertently caused the earthquakes that destroyed the original Maijima Academy school buildings except for the theater.

TWGOK and Seikesshou Albatross exists in the same universe.
Both protagonists of each has to deal with out-of-this-world events that threatens the world, but the settings are a few years apart and in different cities.
 * Seikesshou Albatross has the middle school martial artist protagonist, Yuki, deal with extraterrestrials (Monobails/Monobairus) and the search for their sacred stones.
 * TWGOK has the high school galge playing protagonist, Keima, deal with the supernatural (devils and goddesses) using his skills to fill girls' hearts with love, and exorcise and capture the Weiss.
 * Both are series made by Wakaki Tamiki.
 * Hiroko Matsumaya, A.K.A. "Mappy", and three of the delinquents that appeared in Seikesshou Albatross reappear in TWGOK but they are now in high school. Their families probably moved to Maijima City after a series of mysterious events happened in Kozue City.
 * Mappy's apperances: in Seikesshou Albatross, here and here talking to Rika; in TWGOK, here talking with Chihiro and Elsea.
 * The three delinquents apperances: in Seikesshou Albatross, here and here bullying Asakura, and here wielding their weapons against Yuki; in TWGOK, here and here confronting Elsea and Keima, here Ryou wielding a weapon against Kusunoki.
 * It should be noted that Ryou, the black-haired tall and thin delinquent, wielded two different weapons in his manga appearances. A Butterfly knife in the TWGOK manga, and a collapsible baton in Seikesshou Albatross manga and the TWGOK anime.

Mars is gay.
Not only was she happy to support a relationship between Yui and Keima when she thought that Keima was a girl (which, granted, certainly doesn't require that she be a lesbian herself) but after cutting through Haqua's disguise and seeing that the 'Vintage agent' was a cute girl, she stopped completely in her tracks. Even letting her come back and beat on Keima for a bit before running off.

The third season will have 2 capture targets.
The primary girls will be Tsukiyo and Minami.
 * The season outlook would be roughly like this:
 * Episode 1 would be adapted from FLAG 42: A Demon That's Tiny = The Little Devil! It will also be a recap episode of the previous two seasons.
 * The Tsukiyo Arc will have 3 episodes.
 * Episode 5 would be adapted from FLAG 34 Demolishing The Bricks and FLAG 35 The Dawn of Something
 * The Haqua and Yukie arc will have 2 episodes.
 * The Minami arc will have 3 episodes.
 * The 2-B Pencils and Kanon studying arc will be the last 2 episodes.
 * You forgot to factor in the upcoming OVA. Besides, it doesn't look like a season 3's coming.
 * Yeah the guess is a long-shot, but it would be nice if a 3rd season would be made someday.

Keima being a buddy is a result of a Gambit Pileup
Specifically someone in Vintage tried to sabotage the capture program by sending the invitations to woefully unsuitable people and who better than someone who has about the same level of social interaction as your average Hikikomori? But Heaven or a secret alliance between Heaven and New Hell who know about Keima's interactions with Tenri, host to a Goddess, arrange so that its Keima who is the particular otaku who comes to their attention, thereby sabotaging the attempted sabotage with no one in Vintage the wiser.

Chief Dokuro is running a Batman Gambit on everybody
Knowing that members of Vintage have most likely infiltrated the ranks of the Runaway Spirit Squad, Dokuro figures that finding the goddesses and restoring their power is the most effective way to re-seal the Weiss. She can't play her hand too openly, however, because Vintage would certainly find out and sabotage the plan. After looking over the human buddy candidates, she finds out about the Capturing God, who has the skills needed to restore the goddess's power, but not the motivation. A skilled, studious demon partner would know how unreliable love can be in filling the gap in a target's heart, and would try to persuade Keima into taking a different route. Therefore, she sends the rather naive, but determined and honest Elsie to be his partner, making sure she believes that love is the best tool to use in capturing Weiss. This way, she's able to maintain a hands-off approach and not draw Vintage's attention while Keima gradually figures out the real situation on his own.
 * And Haqua trying to report on Vintage's infiltration of the Runaway Spirit Squad inadvertantly threatens this goal.

Other than the Power of Love, the Goddesses other Power Source is worship.
In a way worship is another type of love. Because nowadays no one worships the Roman pantheon as they did in the past their power is greatly diminished.

The girl who doesn't have a goddess will be the winning girl

 * According to chapter 165, that girl is.

Miyako will have either an unaccounted for goddess or a runaway spirit
Her interactions with Keima in Chapter 127 and his line about not saving her screams Tempting Fate.

The key Keima has in the first color page is the key to sealing away the Runaway Spirits for good

 * Hey, it's possible. Plus, that'd be an awesome Early-Bird Cameo.

Elsie will be Keima's Big Damn Hero.

 * With the situation of dealing with Ayumi and Chihiro spiraling out of control, it'll take the help of their mutual friend Elsie to defuse the ticking bomb that's just waiting to blow up all of Keima's plans, and really drive home how much he actually needs her.

HAQUA will be Keima's Big Damn Hero.

 * With Vintage gearing up for a Zerg Rush in FLAG 174, a free-to-do-as-she-pleases Haqua is going to thwart the rush, bailing out the non-combat orientated Keima BIG TIME.
 * After Chapter 175 we can only say: Here. Take the fucking trophy!
 * Eevee Lord graciously accepts said trophy, until such time as the next WMG is confirmed.

There will be a plot to get rid of Keima's collar.
Vintage appears to have considerable control in Hell. Also, the collar is an execution collar, so Keima is in serious risk of beheading.
 * after the events of FLAG 161, this guess's probability increased dramatically, as  is freed from Vintage sans her collar.

Keima will die before the series end.
Keima will engineer a scenario where he will die in front of the goddess in a Heroic Sacrifice just after he gives a Dying Declaration of Love and being Defiant to the End because he's cool like that.

This, of course, raises all of their love points to the max which gives the goddess enough power to seal/defeat the Weiss and save the day incidentally they are also able to bring Keima Back from the Dead.

Afterwards someone asks Keima why he would do that and he will say something to the effect that he trusted the girls and goddess. Also, that's how that scenario works in games.

Cue Glomp and shock

Chihiro is trying to capture Keima
Okay a friend pointed this out to me on the latest chapter last panel is that a collar!!!?!?around her neck!!! What the bloomin hell is going on there! Could be an error, could be that Chihiro is contracted just like Keima to capture loose souls, perhaps the entire arc was her trying to capture Keima for this purpose! Though even if this is the case she most likely has legitimate feelings for Keima, as she's tearing up when he goes all jerkass on her. Perhaps she was offered this job because of how many guys she tried to confess her love to! Or perhaps the prescense of the collar could simply symbolise the fact that Keima is perceiving her as trying to capture him!

Chihiro is Fiore or Lune's partner
All the new devils in Earth are members of Runaway Spirit Squad (at least on the paper), which means Fiore and Lune have human partners and considering the last panel of the picture posted in the above WMG, Chihiro could be one.

Chihiro will have Super-Powered Evil Side and become Vintage's agent
During her Heroic BSOD, Vintage's agent will approach her, telling her about Vintage and New Hell (their version, of course) and manipulates her so she accepts mission to eliminate Keima and sealing the Goddesses. Powered by despair (or jealousy) (or any other negative emotion she might had) she goes on rampage to destroy Keima and the Goddesses. Sakura Matou's rage will looks like a child tantrum compared to her....

Mari Katsuragi is the host of Demeter
Reflected in her very loving and motherly personality (when she isn't in Badass Biker mode). And as for that, the mythological Demeter was no stranger to the Berserk Button herself, best demonstrated when Hades took her daughter Persephone to the underworld.
 * There may be something to this as it could explain Keima's abiility to capture ladies as changing as the seasons. Of course I wonder if she will go fully berserk for all the girlfriends her son has had.
 * Nah, she'd probably be amazed that he's actually been communicating with real people. Now, if Vintage tried to capture Keima, on the other hand, and this turned out to be true, it'd result in a Mama Bear rampage that'd have them begging to go five rounds with Izumi Curtis instead.

Diana will turn out to be the most powerful out of all the goddesses
Up until now she has been the weakest due to Tenri's shyness and Keima trying to capture the other goddesses as quikly as possible, thus giving Tenri less attention. According to Diana, Tenri's love should still be stronger than anyone else's since she's been in love with Keima for years, so if her powers are weak, it's beacause she herself has fallen in love with Keima, and her guilt is somehow countering Tenri's love. This doesn't mean that her being in love with Keima is bad, but rather her feeling of guilt is the real problem. At some point, Keima, or more likely, Tenri, will say something to convince her there's nothing wrong with her loving someone else's fiancè, and once she is freed of her guilt, she'll be powered by Tenri's love as well as her own, making her more powerful than ever.

Shiori has a goddess.
She already had perfect memory when possessed. She probably hasn't talked to Keima because she's still kind of shy.
 * Chapter 118 confirms that one of the goddesses is Minerva. Minerva is the goddess of wisdom and music, in Shiori's arc, it was shown that she was (very) knowledgeable, and in the epilogue, that she reads music's lyrics sheets. Lastly, she was never shown to completely forget, and said that she still had vague memories.
 * Keima has narrowed her down to one of the most likely candidates.
 * Shiori still has her book-memorization ability. Whether or not it's just carried over from the capture is unknown.
 * Confirmed. Its Minerva.

Sumire has the goddess Vulcan
Loosely, fire is used to cook, cooking is a practice that takes time and effort to make a meal. Like smithing a sword, or thunderbolts.
 * Jossed. Tsukiyo got Vulcan.

Nagase has the goddess Mars
Nagase is a big fan of pro wrestling and always tries to break through to her students, and tries to inspire courage. Much like a certain suspected god(dess).
 * This will be the last goddess Keima finds, to win her over and awaken Mars he must give up galgames, once he does this, Mars will lead the other goddesses into battle against old Hell. Rage Against the Heavens / Apocalypse Wow ending.
 * Jossed as of 120, as she shows no reaction to Keima having a "girfriend."

Kusunoki has the god(dess) spoiler: Mars
C'mon. It fits like peanut butter with jelly. On toast. She's the Heir to the Dojo with a Hidden Heart of Gold. spoiler: Mars is one of the more worshiped gods in ancient Rome; he's the god of war, [[Heir to the Dojo second to only the Big Boss Jupiter. Mars was also the god of agriculture, and the Hidden Heart of Gold she shows matches the description well. Oh and, Mars acts before he thinks. Sounds like someone we know? Doesn't stop there: Kusunoki still has feelings for Keima
 * Jossed. Yui got Mars.

Chihiro has the goddess Vulcan
Chihiro's not very pretty and Vulcan's the ugliest god on Olympus.
 * Jossed.
 * besides the above troper Did Not Do the Research.

Luna is host to a goddess.
Based entirely on the doll's recent behavior. A doll would get a lot of love, and I don't remember anyone saying the host had to be human...
 * As of Chapter 132, Keima definitely seems to have come to that conclusion. Note that Tsukiyo's omake chapter is completely from Luna's point of view - and suddenly, what appeared to be a throwaway gag has taken on an eerie significance. To elaborate further...

Luna is host to Vulcan.
Credit goes to Aea and M.A.D. of the Mangafox forums for noting the following points:
 * Vulcan created Robot Girl helpers to help out in his forge, providing a link to Tsukiyo's "doll" theme.
 * Also, at his birth, he was cast down from Olympus... and went lame as a result. Granted, Luna has both legs intact in this chapter, but the parallels remain valid.
 * ...Jossed! (Heh.) Tsukiyo has Vulcan, and it seems that Luna is sentient and animate as a result of Vulcan's powers.

Assuming the same amount of episodes, the second season of the anime will only have 3 captures.
If you check how many chapters were covered by season 1 (17), and assume the same amount is covered this time, season 2 will have Kusunoki's, Haqua's (though technically not a capture), and Chihiro's captures, finishing off at Chapter 34, 2 chapters before Jun's capture starts.
 * Jossed. The opening says that they squeezed Jun in somehow.

Chihiro has Venus

 * In the irony of ironies, the perfectly middling girl would have the most beautiful goddess in Roman mythology.
 * Also the chapter "Venus in Furs" is a reference to a novel wherein it is framed by the protagonist's talks with Venus in his dreams concerning the nature of love. Since that particular chapter has a focus on how Keima asked Chihiro whether or not they kissed, it is quite possible that she has Venus.
 * Jossed, Venus isn't even an option.
 * Not Jossed yet. Its possible that there is a "Venus" and is inside a girl.
 * Chapter 165 confirms that, so this remains Jossed.

Ayumi has Venus

 * Well, her name does mean beauty after all.
 * Jossed, Venus isn't even on the list.
 * Not on the list but she might still be there.
 * Chapter 165 revokes that argument.

The girl out of the 4 remaining girls that Keima has narrowed them to that doesn't have a goddess is Yui.
Think about it. Yui has actually shown the weakest signs of having a goddess of all of the girls. Going over their general reactions after, everyone has shown signs of anger except for her. Off the top of my head:
 * Ayumi started using a suffix on his name and gave him a Megaton Kick. Not to mention her reaction during the moment of said confession.
 * Shiori suddenly killed off Keima's counterpart in her story in a fashion that shows that she was suddenly angered.
 * Chihiro accidentally spilled coffee on him.
 * Yui, however, just seems to be trying to force cross-dressing on him in an attempt to stop his five-timing, but doesn't show much anger at all.
 * I think you're wrong. Her reflection has a different expression and hair style. I think she definitely has a goddess.
 * One could easily say that the design on her changed, or that she's simply becoming more man-like over time. That doesn't prove anything.
 * I also think Yui is likely to not have a Goddess. She knows about Keima's multi-capture yet isn't mad at all. My guess is even without a Goddess, she will stay in the main cast due to her Yandere tendencies.
 * As of chapter 140, Keima believes that there is definitely a goddess in Yui.
 * He said "there's a good chance", as he said about every other girl so far. That has simply made Yui a bit more likely, rather than the "let's throw her in to keep up the drama" vibe she's been giving off until now.
 * Jossed by the spoilers for Chapter 141.

Yui will have a goddess inside her
Think about it: if she doesn't have a goddess, then she has forgotten all about the capture, thus Keima is a stranger to her. Now, let's say she still has some lingering affection towards him, or she just thinks he's cute, and decides to talk to him. Why the confession? Why insisting on going after him even after finding out he's making a move on other girls(and multiple ones at the same time, at that) as well? This is Keima we're talking about. He's the capturing god, sure, but when he's not trying to capture a girl, he's just your average otaku. Why would a girl, any girl, go after an antisocial otaku playboy? But, if she does have a goddess, it all makes sense. She still loves him, and this explains her behavior; as for the details, I think she's still just starting to remember, since she didn't get much love to feed the goddess. Kanon too didn't remember everything right away, and Yui was captured much later. So what if she didn't get angry? If that was the only parameter to find a host, then Tenri would be out, too. She didn't get angry even after finding out exactly how Keima was capturing runaway spirits, and not because she knows he has no choice, but because she is just so shy, and happy enough to just being able to talk with him from time to time. Yui is, or at least became, much more assertive than Tenri, so she just decided to not care about the rumor about Keima and Kanon and instead is trying to get the guy. And if you add her reflection in the "Yui after" chapter, it takes away every possible doubt. Out of the four candidates, I'd say the one without a goddess is Chihiro, since she is the normal girl, furthermore the author expressly said he likes Ayumi's character, and the fandom seems to like Shiori. The only flaw in this reasoning is that it's far too obvious, so, if not Chihiro, it's either Ayumi or Shiori, but not Yui. Wall of Text.
 * The main point has been confirmed by the spoiler for Chapter 141. You'll have to wait up for the rest of the guesses, though.
 * It has all been confirmed as of chapter 165. I Knew It!.

Ayumi Takahara will have a goddess inside her.
Just because she's my favorite and I'd really like to see more of her. Also, Chapter 108.
 * To elaborate some more, she was the first captured girl and has showed some vague flags to Keima. Like here and here.
 * Yes, thank you, that is exactly what I meant!
 * YMMV but this effort is a little exaggerated.
 * It seems that goddesses have characteristics similar to their hosts (Apollo is the goddess of arts), so perhaps she'll have Mercury?
 * Chapter 118
 * Chapter 119:
 * It should be noted that the goddess does not have to have similar characteristics to the hosts. Example: Tenri.
 * Diana, in mythology, is a goddess of hunt. This trait is seen in Tenri and Diana playing shogi as one has to hunt to down the enemy.
 * iirc, Diana/Artemis is the goddess of young girls and virginity, and often associated with innocence and purity. YMMV, but I reckon Tenri's pretty innocent, and acts quite young (innocently, not immaturely). Also Diana is the goddess of childbirth -> childhood friend.
 * In addition to the above, note that Now while Ayumi was naturally fast on her own before and after the ,  Last point if Keima is right on his theory that   Ayumi is one of the closest girls to him, seeing as they normally get stuck sweeping together, and seem to have a history of doing the chore together
 * as of chapter 165.

Mercury will have more than one host
Consider that Mercury was described as knowing many unusual spells and techniques, as well as the fact that the mythological Mercury was the god of speed and communication. Both Ayumi (speed) and Shiori (communication) are strong, appropriate candidates to be Mercury's vessel who've been shown to react to Kanon's love confession. What if, after getting Apollo's warning, Mercury used some technique the other goddesses don't know about to confuse any potential pursuers by hopping back and forth between the two?
 * Jossed as far as Ayumi/Shiori being the duel hosts, but Ayumi/Chihiro remains a possibility.
 * Ayumi and Chihiro sharing Mercury has been.

There will be a 7th goddess, and she'll be inside extra girl from the current multi-capture.
Nothing in the story says a seventh goddess wasn't born during the time period that the six we know of spent keeping the runaway spirits sealed. Diana certainly wouldn't have had an opportunity to hear about it. This also neatly handles how all 4 girls seem to have some sort of evidence supporting them harboring a goddess. It also conveniently avoids pissing off the fans of certain girls who specifically wanted a goddess in their favourite one. It also helps Keima counteract the consequences of his current actions in relation to the leftover girl, unless their memory will be wiped (which probably won't happen). I could see it happening.
 * I agree, but for the reason that seven is a far more significant number symbolically and religiously than six.
 * If there was a seventh goddess, why would she be in a capture target? The reason these 6 are is because they were released alon with the runaway spirits, but since this 7th goddess wasn't with them there, she wouldn't be there.
