Kyonyuu Fantasy Gaiden

Kyonyuu Fantasy Gaiden, localized as Funbag Fantasy: Sideboob Story, is a side-story-sequel to the Kyonyuu Fantasy H-game that was originally released in 2011, but was finally localized in English in 2018.

With Lute's coronation as king at the end of the first game's canon route, Edelland entered a era of stability. However, executing the treacherous Prince Bobon, which conspired to kills his predecessor Hagel I, didn't came without consequences. The neighbour kingdom of Lingboard invaded thanks to Bobon being the son of the lingboardian queen, but general Gladys crushed his invasion and the resulting treaty made Lingboard lose a chunk of their territory to the invaded.

Instead of ending tensions, however, this only further brought attention to Edelland: the kingdom of Fronce, that was a lingboardian ally, saw Edelland as a threat, while the State of Vacatin, the headquarters of the Church of Holy Rood, saw Lute's marriage with a succubus as sinful, if not preposterous. Not only because queen Shamsiel is a demon, but because she killed innocent people.

Meanwhile, prince Argent, cousin of Prince Bobon, goes to the Kingdom of Fronce to try to obtain some help to dethrone Lute. He is given a magical item by Marquis Cuvier, one of the people closest to the queen that does want to dethrone Lute but also knows the queen dislikes the idea of a war.

Soon after, Edelland is attacked by a magician commanding a evil spirit, that apparently drives a soldier to suicide. The ambassador of Fronce arrives soon after and, with Lute stuck in deep sleep, Gladys decides to take on his duties, even if she isn't his official spouse. Yet.

Directed by Fuurin Ebimaru, Himenomiya Rei,Natsumi Kansai, and Ushitarou. Developed and published by Waffle on Japan and Mangagamer on English.

Tropes used in Kyonyuu Fantasy Gaiden include:

Actually Pretty Funny: Lute takes the insults of "His Lewdness" and "Boob King" with unbridled pride.
Aw, Look -- They Really Do Love Each Other Lute truly loves each and every one of the members of his harem, and he tries to convey that, but the tricky part is they kind of get competitive for it, so much so that eventually they had to set up "rules": A daily lottery to determine whose breasts he would suck milk from during meals, a single night each week where he would sleep with only 1 of the girls (thereby giving them both privacy AND his full attention), and then an orgy with all the girls every other night of the week.
Battle Harem Lute's harem at the start contains: A succubus (the 2nd highest class of demon), a former rebellion leader who is regarded as the best knight in the entire continent (in nearly every way), a Royal Knight that was the 2nd highest scoring graduate of the Knight's Academy, a scholar with enough magical knowledge to be able to use spells to enslave someone's will, a princess whose body possesses special demonic traits that make her just as lethal to fool around with as a succubus, AND a strong-willed woman of nobility. Not to mention, by the end, the roster goes up with the addition of a truly high-grade magician AND a swordswoman who is actually the Queen of Fronce aka one of the major powers on the entire continent.
Beauty Equals Goodness: Averted at times. While many of the ugly or at least non attractive characters are evil, a few are genuinely good or at least misunderstood. On the human side, we have Agatha, leader of the Church of the Holy Rood, who is one of the few of his colleagues who isn't an overbearing Hypocrite. We also have the Cyclops, who was misunderstood, not evil. Played straight with Lute’s harem.
Biblical Motifs: The religion in-universe bears many similarities to Catholicism, and at one point Lute makes a direct reference to Mary Magdalene and her former history as a prostitute.
Blonde, Brunette, Redhead: Luceria, Roxanne, and Shamsiel respectively. They are also the trio who are first married to Lute at the start.
Cassandra Truth: Nellis constantly tries to give Bazalt some advice but his lust for power makes him ignore everything.
Christianity Is Catholic: Barely averted. While it's in-universe Expy is heavily modeled after it, it's got enough key differences from IRL Catholicism to qualify, such as a rather liberal idea of what actual virtue qualifies as, not to mention a lack of focus on a lot of the actual sacraments from the IRL version.
Chronic Backstabbing Disorder Or perhaps it'd be better to say "Chronic 'trying-to-manipulate' disorder", since many of the enemies Lute encounters are either trying to manipulate him or others and/or are being manipulated themselves by someone else.
The Corrupter: Roche takes almost no time after meeting Lute to try to convince Gladys to stab him in the back, supposedly in the name of the greater good.
Drag Me to Hell Anyone who opens Pandora's Box, but is deemed corrupt, basically has this happen to them. Compliments of Saint Reaper.
Everybody Has Lots of Sex In keeping tradition of the first game. Just about every single named female character that appears on-screen has a scene of this at one point.
Face Framed in Shadow: Despite the fact her identity is not a secret in any way, the queen of Fronce first appears like that, and nobody ever refers to her by any other term than "queen".
Fanservice As with the first one, this game is brimming with it. (Quite literally.) To the point where, even the game's hub has 2 naked women with huge boobs striking sexy poses at opposite ends of the control panel.
Fantastic Racism Lute may have married Shamsiel after removing the Demon Extermination Law, but that doesn't mean everyone just accepts demons among them so easily. In fact, a good portion of the story has to do with the villain trying to manipulate the Church of Rood into trying to discredit Shamsiel and turn the people against her. It ALMOST works.
Gag Boobs Oh man... The trend continues with nearly every single female character introduced having a pair of huge knockers. That said, this one actually contains the first female character introduced to have no outstanding assets.
Gaiden Game: As the name says, though it's more a direct sequel and follow-up to the True Ending of the previous game. It picks up 2 years after the 1st game's ending (which is actually 1 year after the epilogue).
Game Breaker In the last game, Shamsiel was able to overcome nearly anything with ease, but this time it seems they toned down her powers a bit. Granted she's still more than capable of easily kicking major ass all over the place when needed.
Harem Hero: Lute starts off this way, officially married to three of his harem members, and is just as bound to the others even if it's not "official".
Hypocritical Humor: The exact same soldier that complains about Lute being a breast lover boasts about the queen of Fronce's large breast size a few sentences later.
Immodest Orgasm: It's a nukige visual novel with all female characters voiced... NONE of them are quiet about it.
Jump Scare Shamsiel attempts to use this on someone she was spying on, in an effort to confirm whether or not they were actually able to sense her.
Killed Mid-Sentence Surprising how many people have this happen in the story.
Love Across Battlelines Lute and the Queen of Fronce fall in love by the end, but they aren't able to marry, because both want their nations to maintain independent sovereignty.
Marshmallow Hell It actually saves Lute's life during an instance where a golem starts attacking.
Non Action Hero Lute gets put in several situations where he could have died, but never once does he actually do the fighting himself. Instead he opts to try and find more peaceful ways to solve problems, but that's not to say he doesn't put his life (and in some cases, his very soul) on the line to protect those he cares about.
No Communities Were Harmed: Pretty obvious with names like Fronce (France) and Vacatin (Vatican). Since the Iberian Peninsula was only briefly united between 1580 and 1640 and the crowns were never united, they actually use the name Iberia, averting the trope, though it's more of s stand-in for Spain since Portugal never was a Great Power.
Only Sane Man: Who actually qualifies as one during the plot is a recurring theme. Most of Lute's enemies think the only one on his side is Gladys, whose competence is well known despite her penchant for skimpy daywear. Even among Lute's allies, only Emeralia seems to be able to keep her mind focused on actual business most of the time. Cuvier thinks he's the only one on his side who qualifies because of obsession with seeing Fronce remain the dominant power on the continent at all costs. Bazalt of Lingobard actually lashes out at the sane people from his kingdom, which they recognize despite their own flaws, and the cardinals of the Church who actually qualify are generally those with the least overweening ambition.
Parental Substitute: It's implied Lute became one, at least officially, for Gladys since her father is deceased and she asks of his authority over she marrying a froncian noble or not.
Practical Effects This game makes good use of its special effects and visuals to bring forth a far more entertaining experience than the first one. It does a LOT with what it has.
Puppet King: Despite not being one, Lute's liking for large breasts makes neighbour countries dismiss him as simply being a placeholder and Gladys and Felzen as the real rulers of Edelland.
Quick Draw Decision At one point Lute asks Saint Reaper to help him out by getting rid of the Fake Shamsiel and Ghouls that had been attacking them. Saint Reaper tells him that he wouldn't work for someone for free no matter who, and the cost would be Lute's soul. Lute tells him that's fine, and that he could have it if he beat him at rock-paper-scissors. Before the onlookers even have a chance to try and stop him, they conduct the game and Lute wins. When asked about what he would've done if he had lost, Lute told them he figured he'd go see the sights of Hell.
Reality Ensues: This game explodes the conceit the True Ending of the last game meant everything would be fine for Lute. In fact, this game covers all the loose ends and political resentments the previous game planted the seeds for.
Royals Who Actually Do Something: Drives the plot. Lute is considered a lazy Handsome Lech by his enemies, and while they aren't wrong to some extent, he's actually much sharper than he let's on, purposely weaponizing that perception of himself so his Obfuscating Stupidity continues to work for him.
- His enemies also happen to be largely royals themselves, and they are attempting to be this trope to gain an advantage over Lute politically.
Running Gag: This game continues the incredibly dumb Faceless Mooks assassins gag from the first game, complete Lute foiling their schemes to a point it's insulting.
Shut Up, Scary Thing! When the fake succubus tries to attack the men at Vunderbalt, they immediately know she's a fake and start attacking her (verbally AND with weapons) until she flees.
Took a Level In Badass Pretty much all the characters who returned from the first game, demonstrate themselves as becoming even MORE badass than they were in the first.
Unlikely Hero Most of the foreign powers in their world are uncertain how they should actually view Lute. Some think he's just a pervy idiot who got lucky, others just don't bother with him at all. It makes it all the more satisfying when they actually meet him and once they've gotten to know him, they see how truly capable as a ruler and how kind he really is.
World of Buxom: The game takes note all Lingboardian women are well-endowed.
Victor Gains Loser's Powers Lute has a bet with Saint Reaper, if he had lost, Saint Reaper would have taken his soul, but since he won, Saint Reaper had to lend Lute his services and take out the fake Shamsiel and Ghouls that were trying to kill him and his friends.
Ye Olde Butcherede Englishe: Used somewhat, but in the manner of a Translation Convention. While most in Edelland speak modern English, the translation has the others from foreign countries make moderate to heavy use of this trope to distinguish the foreignness of their native languages. It's especially prevalent with characters from Fronce, which is rather logical, as Edelland is basically a Prussia Expy.
