Isekai by Moonlight/Characters

Characters from , as of the end of the second chapter, include:

Original Characters
In order of appearance:

"Robu-san" Donaldson / Oni
"Stupid genre conventions."

- Robu-san's Catch Phrase


 * First appearance: Chapter 1.
 * Licence status: Not available to other writers

The Protagonist of Isekai by Moonlight, the story is told from Robu-san's perspective.

At the beginning of the story, he's a 14-year-old white male in Japan, who stands 183 cm tall. Despite this, there are enough other tall white men in Minato (because of all the embassies in that part of Tokyo) that nobody has yet figured out his secret identity. (Well, except for a couple of opponents who ended up dead so it doesn't count... and Sailor Pluto already knew.) Robu-san's birthday is July 7, Tanabata.

Usagi inadvertently gave him his non de guerre "Oni"; it's the first word that she said to him.

A full description of Robu-san would include major spoilers for the story. However, it isn't much of a spoiler for a story titled Isekai by Moonlight to reveal that he's Trapped in Another World.


 * Affectionate Nickname: The "True Companions" version; Robu-san calls Tsukino Usagi "Bunny-chan" and Artemis "Artie".
 * First-Name Basis: With most of the Senshi, and with Ami's mother.
 * Genre Savvy: His early blind spot about his relationship with Makoto notwithstanding. Early in the first chapter, he worries that "Stupid genre conventions" is becoming his Catch Phrase.
 * Nom-de-guerre: "Oni" was given to him accidentally by Usagi; it's the first thing that she called him (because of his height), he used it in an I Know You Know I Know situation, and it stuck.
 * Official Couple: With Kino Makoto, as described in her writeup. The two are on a "first name without honorifics" basis by the end of the first chapter.
 * The One Guy: For part of the first chapter, when (as in canon) Tuxedo Kamen was kidnapped.
 * New Transfer Student: How Robu-san enters the story.
 * Sarcastic Clapping: One of Robu-san's favourite ways to draw attention to himself and away from the Sailor Senshi. The trope being unknown in Japan in the early 1990s, the clapping serves less as a psychological attack and more as a distraction.
 * Super Empowering: In his backstory.
 * Trapped in Another World: He's the Protagonist in an Isekai story; this trope's pretty much a given.
 * Trapped in Another World: He's the Protagonist in an Isekai story; this trope's pretty much a given.

Sato Kichirou

 * First appearance: Chapter 1.
 * Final appearance: Chapter 1.
 * Licence status: Available to other writers upon request.

A rather Flat Character, who existed to give Robu-san and Ami a classmate that they didn't want to spend time with or share their secrets with. He ended up.

Aoyama Ichigo
""I think I've figured it out," she said after being introduced to Hino-san. "You're the Sailor Senshi that I remember hearing about during the Missing Time.""

- Chapter R


 * First appearance: Chapter 1.
 * Licence status: Available to other writers upon request.

Ichigo Aoyama is just an Ordinary Junior-High School Student, who is a classmate to the decidedly not normal Makoto Kino. At the start of the story, she's 14 years old, she stands 166 cm tall, and her birthday is January 22. Ichigo wears her black hair at shoulder-length.

She was born and raised in Wakkanai, Hokkaido, the third of three children. Her father and both of her brothers are deep-sea fishermen. Ichigo and her mother moved to Tokyo so that she could get a better education than what was available in Wakkanai; Ichigo wants to become a marine biologist and study her home town's harbour seals. She loves the biological sciences, and absolutely hates Japanese History to the point that she needs to take supplementary lessons in that class.

One reason that she hates Japanese History class is because it teaches her some things that her family tell her aren't true. Ichigo knows more about the Ainu than most college students... because she is Ainu herself. This isn't something that she tells very many people; when pressed, she says she has Ainu ancestry without saying that it's on both sides of her family. Ichigo has the Ainu depressed nose root and projecting cheekbones.

She knows "a smattering" of Russian, which she admits to speaking with a thick Japanese accent, from the occasional trip to Korsakov. She loves downhill skiing.

She often speaks without thinking first, which leads to the occasional awkward moment.


 * Secret Keeper: For both the Sailor Senshi and Robu-san, partway through the second chapter.
 * The Team Normal/Ordinary High School Student: While she isn't a formal member of the team, she isn't a Magical Girl Warrior or a Designated Victim, either.

OC Stand-Ins
The section headers link to the canon character descriptions. Again, in order of appearance:

Urawa Ryou
""This should be interesting." When a precog says something like that, it's best to play along."

- Chapter R


 * First appearance: Chapter 1.

No longer a two-episode guest character, Ryou transfers to Kuritsu Juban Chuugakkou during the second chapter in order to get a better education than he could get back at home – which for the purposes of Isekai by Moonlight is the port city of Niigata (based solely on the fact that we saw him board a shinkansen to return home at the end of his first appearance). He still has his precognitive power, although he can't see a definite future; instead, he sees a number of possible futures and has to figure out which one is most probable or most desired... and if those two futures aren't the same, he has to take steps to make the future he wants come about.

One future that Ryou-san didn't need to work to make happen is the one where he and Ami fell in love. By the end of the second chapter of Isekai by Moonlight, Ami and Ryou are the story's Beta Couple.

For the purposes of this story, Ryou's birthday (never established in canon) is December 23, which makes him a few months younger than his girlfriend.


 * Ascended Extra
 * Beta Couple: With Ami, as described above.
 * Seers: As mentioned above.
 * Spell My Name with an "S": "Ryou" instead of the canon "Ryo", as a subtle reminder that this story takes place in a close parallel of the canon anime timeline instead of in the canon anime timeline itself.

Mizuno Saeko
""Would you be happier if I forgot what's been said here today?""

- Chapter R


 * First appearance: Chapter 1.

Isekai by Moonlight is using Mizuno-sensei's given name from Pretty Guardian Sailor Moon. No longer a one-episode guest character, she spends a lot of time on-call at the hospital in order to pay for her daughter's juku, but unlike in canon she isn't completely absent from Ami's life.

Early in the second chapter, she decides to become an unofficial parent figure to both Makoto and Robu-san, neither of whom have living parents in the story. Later in the second chapter, she was in the audience for the Snow White play that was staged in episode 56 of canon, and demanded an explanation as to why her daughter claimed to be a transforming heroine when Ami arrived home that evening. As a result, she's aware that Ami, Makoto, and Robu-san are Sailor Mercury, Sailor Jupiter, and Oni, respectively. A later slip of the tongue lets her in on Sailor Moon's identity as well, which she offers to keep secret from the Tsukino family.


 * Ascended Extra
 * Glamorous Single Mother: Downplayed, in that she is sometimes working overtime instead of at home, but that's because she needs the extra money for her daughter's education.
 * Good Parents/Open-Minded Parent: Once she learns that her daughter is Sailor Mercury, her main interest is in what it's like to be a transforming heroine.
 * Parental Substitute: For Makoto and Robu-san, once she learns that they have no living parents and are close friends with her daughter. She's just as much an Open-Minded Parental Substitute as she is an Open-Minded Parent.
 * Secret Keeper: For Usagi, Ami, Makoto, and Robu-san, by the end of the second chapter.

Changes (if any) to Canon Characters
Starting with the two who have major roles in Isekai by Moonlight, then listing the others alphabetically by family name.

The section headers link to the canon character descriptions.

Kino Makoto / Sailor Jupiter
Makoto is the deuteragonist of Isekai by Moonlight and Robu-san's girlfriend. He trusts her with all of his secrets, including the ones that hurt, and in return she trusts him with all of her secrets, including the ones that hurt. And that trust has turned into love. She knows that Robu-san will never willingly lie to her, although he's reserved the right to remain silent or to give a misleading answer. By the end of the first chapter of Isekai by Moonlight, Makoto and Robu-san have kissed, and are the story's Official Couple.

She and Robu-san developed a "Jupiter Railgun" attack during the first chapter of Isekai by Moonlight, and she unlocked the canon manga attack "Jupiter Coconut Cyclone" during the story's second chapter.

Extrapolating from canon, the plane crash that killed Makoto's parents has been established in-story as the JAL123 crash, which in the late 1980s and early 1990s in Japan was what was understood to be the case when anyone mentioned a plane crash without saying which one. Considering her canon nervousness when she hears aircraft, and her near-compulsion to keep things clean, this story's Makoto has been established in-story as having been aboard the 747 with her parents, and is one of a small number of people who survived the crash in that reality who died in real life. And she hates the minor notability that this brings, which is why people rarely talk about it.

She's a bit jealous of anyone else who Robu-san might notice as a romantic interest. But only a bit. She's willing to transform to and from Sailor Jupiter in his presence (but not any other man's presence), giving him the occasional "eyefull". She isn't happy that they're waiting until she's 16 before taking their relationship to the next level, but understands why that has to be.

"Considering how messy an aircraft crash usually is, I could understand why she was a neat freak."
 * Character Focus: She appears in more, and longer, scenes than any of the other Senshi.
 * First Girl Wins: In the first chapter, no less.
 * Neat Freak: As in canon, but given a reason here that ties in with her parents' death.


 * Official Couple: With Robu-san, as described above.
 * Raised by Grandparents: Mentioned in the second chapter, but the fact that Makoto lives alone shows that their parenting style is extremely hands-off.
 * True Companions: Thanks to Mizuno-sensei becoming Makoto's Parental Substitute in the second chapter, the canon friendship between Makoto and Ami has only grown closer. At one point, Makoto says that they're "sisters in all but blood".

Mizuno Ami / Sailor Mercury
Ami-san is still the genius of the team. She has a boyfriend in this story; see the write-up for Urawa Ryou for details.

Like Makoto, Ami knows that Robu-san will never willingly lie to her, although he's reserved the right to remain silent or to give a misleading answer.

Her canon very-mild Innocent Fanservice Girl tendencies have been played up slightly; she honestly doesn't care whether Ryou or Robu-san do or don't see her naked, which saves a bit of time when she needs to transform to or from Sailor Mercury in their presence. This is explained in-universe by her having the same attitude toward skin that most doctors and medical students develop.


 * Beta Couple: With Urawa Ryou, as described in his writeup.
 * True Companions: Thanks to Mizuno-sensei becoming Makoto's Parental Substitute in the second chapter, the canon friendship between Makoto and Ami has only grown closer. At one point, Makoto says that they're "sisters in all but blood".

Aino Minako / Sailor Venus
In Isekai by Moonlight, Minako transferred to Kuritsu Juban Chuugakkou instead of the canon Shiba Kōen, and she asked to have a Conversational English club created when she transferred in. Since the club's founding members are Minako, Ami, and Robu-san, this has turned into an unofficial planning forum for the Sailor Senshi who are fluent in English... at least when club advisor Sakurada-sensei doesn't sit in on club meetings.

As of the end of the second chapter, Minako is usually still the serious mature girl from the first season of Sailor Moon, not the malapropism-spouting goofball that she becomes starting in episode 78 of canon. She's also developed a non-canon close-in energy attack, "Crescent Beam Saber".


 * Darker and Edgier: The events of the Sailor V manga are included in the backstory of Isekai by Moonlight... which means that, unlike in the canon anime, Minako has blood on her hands.

Artemis
Robu-san is one of the few people who can get away with calling Artemis "Artie". He's been shown to take a role in running the Crown arcade, and is responsible (after Robu-san suggested it) for the Sailor Moon toku shows that exist in Minato (including the one seen in canon). He does remember what it means to be a Mau, although he never transforms between cat and human forms where Luna can see him. He spends most of his time in cat form.

Artie is the only person who Robu-san trusts with access to his collected data.

Chiba Mamoru / Tuxedo Kamen
No changes yet, other than Mamoru knowing Robu-san and him knowing he's Tuxedo Kamen. Unlike the others, they are not on a given-name basis as of the end of the second chapter of Isekai by Moonlight. Mamoru's still Usagi's boyfriend and protector, and he's probably still going to become King Endymion eventually.

Hino Rei / Sailor Mars
No changes yet, other than Rei knowing Robu-san and him knowing she's Sailor Mars. She's still a shrine maiden without a boyfriend, no matter how much Yuuichirou-san would prefer otherwise.

Luna
No changes yet, other than Luna knowing Robu-san and him knowing – and telling her – that she's a Mau. He didn't tell her what that meant, though.

Meioh Setsuna / Sailor Pluto
Because of the right royal mess that Robu-san is making to the timeline simply by being in it, Sailor Pluto has four versions of herself involved in the story. The version in Crystal Tokyo is coordinating the actions of the other three: the Silver Millennium Pluto guarding the Door of Space-Time, the Setsuna Meioh native to the current time who is enrolled in medical school, and a Setsuna from between the current time and Crystal Tokyo, who owns and operates Atelier Lucent, a trendy clothing store on Center Gai in Shibuya (thus explaining at least some of the contradictions in her canon backstory).

Atelier Lucent's Setsuna has spoken with Robu-san, months before the contemporary Sailor Pluto canonically makes contact with the other Sailor Senshi. She's also made a few outfits for Makoto, not that Mako-chan realizes who her favourite fashion designer is. (Although Atelier Lucent isn't on the approved list of sources for the Kuritsu Juban Chuugakkou school uniform, so Setsuna can't help Makoto there.)

Osaka Naru
""If it was supposed to be a secret, you shouldn't have dropped so many hints.""

- Chapter 1

Unlike in the canon episode 32, Zoicite didn't miss when he tried to turn Naru into a youma. This pissed off Sailor Moon to the point where she let slip a couple of things that she shouldn't have, and once Naru was refreshed, she confronted Usagi, Makoto, and Robu-san about their secret identities. The Senshi quickly brought Naru into their confidence. When Luna restored the Sailor Senshi's memories at what in canon was the beginning of Sailor Moon R, she restored Naru's memories at the same time.

Her brief time as a youma left Naru with a metahuman power to create gemstones (but only diamonds in the first chapter of Isekai by Moonlight), and a transformation complete with kabuki makeup in the mukimi kuma style when she thinks that she's in peril. As of the end of the second chapter, the meaning of this makeup is unknown.

Naru does not keep any of this secret from her mother.


 * Secret Keeper: For the Sailor Senshi and Robu-san, by the end of the first chapter.
 * Super Empowering: The abililty to create gemstones might not be a combat power, but it's still a power.
 * Took a Level in Badass: The ability to create gemstone-bladed swords on the fly, though, is a combat power that she develops in the second chapter.

Usagi Small Lady Serenity
No changes yet, other than Chibiusa knowing that Robu-san knows her real name.

Tsukino Usagi / Sailor Moon
""I'm stuck with that nickname, aren't I?""

- Chapter 1, just after Robu-san inadvertently calls her "Bunny-chan" and the others run with it

No changes yet, other than Usagi knowing Robu-san and him knowing she's Sailor Moon. She's still probably going to become Neo-Queen Serenity eventually.

Like Makoto and Ami, Robu-san will not willingly lie to her (although he's reserved the right to remain silent or to give a misleading answer). Unlike Makoto and Ami, she does not know this.

Umino Gurio
After he ran for safety when she was turned into a youma, Umino and Naru are no longer a couple. Then An drained his energy past the point where he could recover quickly during preparations for the Snow White play, and he won't recover for months. In essence, he's been Put on a Bus.

The other Sailor Senshi
Isekai by Moonlight has not progressed to the events of Sailor Moon S yet, let alone Sailor Stars, so the other Senshi have not yet appeared. Robu-san did mention to Makoto and Ami in the first chapter that Sailor Neptune is the elegant one, though.
