Characters: Touhou Other Official Works
Ever since the Touhou
series was rebooted for Windows-based computers, a number of characters have been introduced solely though side stories in the form of manga, prose fiction, and music CDs with liner notes.
This page is for Touhou
characters who debuted in these non-game spinoffs. To see the characters who debuted in the PC-98 games, go to Touhou PC 98
. For the Windows characters, go to Touhou Windows One
, Touhou Windows Two
, and Touhou Windows Three
Wherever possible, character images come from portraits not drawn by ZUN
used in official games and print works. Images of characters without quality official portraits are labeled "(fanart)
Please remember to only use examples that are either canon
or have undergone mass Memetic Mutation
so that the page doesn't become overcrowded with tropes that only occur in one person/circle's works.CONTAINS SPOILERS
Concerning the romanization of names
First, there are two principal methods for transcribing Japanese names into Latin letters: the Hepburn System
and the Kunrei-shiki System
. In general, ZUN
favored the Hepburn System before Phantasmagoria of Flower View
, but changed to the Kunrei-shiki System afterward. This page uses the Hepburn format for the sake of argument
, as it is the most widely recognized and makes the pronunciation obvious to English speakers.

Debuted in Curiosities of Lotus Asia
- Store Owner of Kourindou
- Rinnosuke Morichika
"Business or not, a terrible waste is a terrible waste."
The owner of the shop Kourindou, he uses his power to identify strange objects with True Names
and figure out their function. Thus, his shop deals with objects from outside of Gensokyo that won't be easily identified, like his own oil-burning heater, a Gameboy (which he mistook for an Artifact of Doom
) and various knick-knacks that Marisa gathers from time to time.
Tropes associated with Rinnosuke:
- Childhood Friends: With Marisa. Rinnosuke used to work in her father's shop.
- Clueless Chick Magnet: Sometimes treated as this in fanon, as an extension of his status as a Know-Nothing Know-It-All and The One Guy.
- Collector of the Strange: In addition to selling goods from the outside world, he also likes to collect them and is reluctant to part with his merchandise.
- Fan Disservice: Fanon only. Rinnosuke is sometimes portrayed as an excessively muscular pervert who wears nothing but fundoshi loincloths. This version of Rinnosuke is usually referred to as "MANnosuke". Just look up the two doujins "Another Dream" issues one and two... bring your own Brain Bleach.
- Half-Human Hybrid: Half-human, half-youkai.
- Idiot Hair
- In-Series Nickname: As a result of the name of his shop, Marisa calls him Kourin.
- I Should Write a Book About This: Is currently writing his memoirs, and fantasises about it becoming Gensokyo's first history textbook (to the point where the introductory passage is "The history of Gensokyo has been born.").
- Know-Nothing Know-It-All: "By the way, Rinnosuke's supposed vast storage of knowledge comes almost entirely out of thin air. Indeed, he doesn't know nearly as much as he thinks he does."
- When a rainstorm appears localised on his shop, Rinnosuke's first thought is that the Sword of Kusanagi (which he added to his collection recently) must be declaring him the rightful Emperor of Japan, claiming that there can't be many beings around who are powerful enough to manipulate the weather. Turns out the rain was created by a fairy.
- He also seems convinced that once his memoirs are finished they'll become the official history textbook of Gensokyo, and make him rich and famous.
- Leitmotif: "Curious old Shanghai tile" from his appearance in Touhou Unreal Mahjong (a fangame, but his theme was composed by ZUN).
- Magitek: Despite his poor understanding of Outside World technology and not (apparently) being capable of magic, he was able to create Marisa's Mini-Hakkero by combining both.
- Meaningful Name: Morichika means "near the forest" (the location of his shop) and Rinnosuke means "helps the long rain" (he has relationships with the Kirisame family, Kirisame meaning "drizzle"). Chapter 26 of Curiosities of Lotus Asia also has him discussing the possible meanings of Yukari Yakumo's name.
- Mr. Exposition: Or so he seems to fancy himself. He spends an awful lot of time explaining how things in Gensokyo work to Reimu and Marisa or else just narrating about it at length. ZUN, however, has mentioned that most of Rinnosuke's wisdom is his own speculation.
- Namedar: His ability is to recognize the name of an object and its purpose. This doesn't come with the instruction manual. For example, his ability tells him that an iPod is capable of "storing and playing a lot of music", but it doesn't tell him how to store or play anything, and he doesn't know how to use a computer correctly anyway.note And because it neglected to tell him that the people it controls and the worlds it can create or destroy are imaginary, he thought that a Game Boy was an Artifact of Doom.
- Non-Action Guy: Despite his half-human, half-youkai nature, he doesn't seem to be any tougher than a regular human, and he admits that he's unable to do anything rough. Lampshaded by Marisa and Reimu, who wonder how he managed to live so long without knowing how to handle himself. This has resulted in fanon holding that he's a Retired Badass.
- The One Guy: The only humanoid male character in the series to make an actual appearance... apart from a single-chapter character from Wild and Horned Hermit.
- Scary Shiny Glasses: Very shiny ones in HM.
- Shop Keeper
- Stoic Spectacles
"I know the one in red is in there! She's the one that took my books!"
An unfortunate book-reading Youkai who was beaten up by Reimu, who mistakenly assumed she had stolen some books
. When she tries to get them back, she gets beaten up by Marisa.
Tropes associated with Tokiko:
- No Name Given: Canonically, Tokiko has no actual name. If we were to get technical, she'd be listed here as "unnamed book-reading youkai", but that doesn't roll off the tongue as nicely. "Tokiko" translates to "little crested ibis", and was given to her after fans noted her resemblance to the bird in question.
- One-Scene Wonder: She appeared in one scene in one chapter of one series which half the fans don't bother to read, with no name and a small appearance in the background of the cover image. She spent that time getting beaten up twice and complaining about it. She's not incredibly popular, but yes, even Tokiko has a following.
- Winged Humanoid
Debuted in Ghostly Field Club
- Maribel Hearn
"Don't you get it yet? Dream and reality are the same thing. I said so all the time, didn't I? To me, talking to you now might be dream or reality, I don't quite know..."
A human from outside the border, she is one of the members of an Occult Studies Club. She has the power to sense and possibly cross boundaries, and has entered Gensokyo (among other places) in her dreams. Maribel and Renko apparently come from Twenty Minutes into the Future
, where some foods such as bamboo shoots and strawberries are only available as synthetics
. Not only are many edible plants extinct, but it is a world where "children do not smile".
Probably has some sort of connection to Yukari Yakumo
, though when asked by fans ZUN has declined to elaborate
Tropes associated with Maribel:
- Astral Projection or Teleporters and Transporters?: Mary can travel to other places in her dreams, though she doesn't have much control over the destination. It's unclear whether she actually teleports, or whether it's astral projection and Your Mind Makes It Real is in effect.
- Captain Ersatz: That hat looks like Yukari's and they both wear a purple dress in the same fashion. Conveniently, Yukari is known for being a heavy sleeper during the day, a time when Maribel would most likely be awake. Renko believes that Maribel's ability to sense boundaries is somehow evolving into the ability to manipulate boundaries (the same ability as Yukari), while Yukari is often known for recognizing Outside World technology. She detests lycoris flowers (a plant that symbolizes death also known as "higan bana" in Japanese) and Yukari explicitly states that if she ever was in a fight against Eiki Shiki (the judge of death in Gensokyo whose stage was covered with these flowers), Yukari would lose. In Symposium of Post-mysticism, Yuyuko (Yukari's best friend) is depicted visiting the Outside World invisibly and teasing a confused Maribel. Finally, Maribel mentions wanting to visit the moon and thought of "another way to get there" while looking at its reflection; Yukari mentions that long ago she once travelled to the moon using its reflection, just to look around. Make of that what you will.
- Cassandra Truth: Between the events of Trojan Green Asteroid and Neo-traditionalism of Japan she's sent to hospital for her injuries. While she's there the doctors diagnose her with delirium.
- Leitmotif: "Mary, the Magician" and "Strange Bird of the Moon, Illusion of Mysterious Cat". In addition, fans sometimes associate the Sealing Club with "Kid's Festival ~ Innocent Treasures" (ZUN's personal theme).
- Meaningful Name: Lafcadio Hearn, a famous horror writer who translated tales of youkai into English, eventually became a Japanese citizen and took the name Koizumi Yakumo. Following the Yukari theory, Hearn would correspond to Maribel and Yakumo would correspond to Yukari after her naturalization in Gensokyo (canonically "Yukari Yakumo" is a name Yukari chose for herself; her original name has not been given).
- In addition, it's been suggested that Mary's first name is a corruption of "mulberry", a fruit that turns dark purple when it's ripe. Yukari means "violet".
- Non-Specifically Foreign
- Ofuda: Sometimes depicted using these in fanart, presumably because of Yukari's mastery of Onmyodo.
- Schrödinger's Butterfly: Whether or not she's Yukari, Maribel does have a dual existence in Gensokyo in her dreams.
- Spell My Name with an S: Her first name is occasionally romanized as "Maryberry" or the like, and her last name is occasionally seen as "Han". Some places also spell Renko's nickname for her as "Merry".
- More specifically, the katakana for her name is "maeriberii haan". "Han" and "Hearn" are both reasonable transliterations for her last name, though "Hearn" is a bit closer and has the bonus of being an actual western name. "Maribel" is only sort of similar to how her first name is pronounced, but is an actual name. "Maryberry" is much closer, but not an actual name.
- Theme Naming: To support the Lafcadio = Maribel theory, The Wiki Rule even gives this for the first four CDs (Lafcadio —> Maribel):
- Ghostly Japan —> Ghostly Field Club (ZUN wanted the same feel as the source material);
- Exotics and Retrospectives —> Retrospective 53 Minutes (egregious number of references to paintings, Mount Fuji, and "the beauty of memory");
- Kwaidan: Stories and Studies of Strange Things —> Changeability of Strange Dream (youkai horror stories; "kaidan"/"kwaidan" itself literally means "ghost stories"); finally,
- The Romance of the Milky Way —> Magical Astronomy (a "mirror maiden" travels to the moon and has some fun; former is the last by Lafcadio, while the latter is the last one for almost six years).
- Time Travel: A message Maribel left behind on one of her trips to Gensokyo was discovered by the natives... hundreds of years ago. The running theory is that she will eventually become Trapped in the Past.
- The Unfrozen Caveman Lawyer: Maribel's personality seems kind of meek. Yukari on the other hand...
- The Unpronouncable: To Japanese speakers at least, leading Renko to just call her "Mary". Also extends out of universe somewhat - see As Long as It Sounds Foreign above.
- What Do You Mean, It's Not Symbolic?: Fanon has made many interpretations of the above "Maribel = Yukari" theory. It is also even harder to dismiss the fact that her appearance is practically Yukari but younger.
- Renko Usami
"Let's wake up! Dreams are things to be made into reality. The world of dreams can be made into reality!"
Maribel's friend, who lives outside of Gensokyo, and the other member of the Occult Studies Club. Renko initiates most of their activities. She has the ability to determine her exact position and the current time by looking at the moon and the stars respectively. Some fanworks have her sense coordinates in imaginary numbers whenever she tries to sense her location in Gensokyo.
Tropes associated with Renko:
- Agent Scully: A notable subversion. Renko is the scientific, logical, objective one of the pair and shoots down some of Maribel's odder notions, but she's also much more enthusiastic about their occult activities, driving their investigations and efforts to find another world.
- Encyclopaedic Knowledge
- Info Dump: Unless she takes it easy, she likes to go nuts on anything she has learned.
- Fatal Flaw: Curiousity. Despite the fact she knows a lot about the real world and how it functions, she has an overpassionate desire to learn what she does not know or cannot comprehend by theories. For example, while in TORIFUNE, she has no fear of learning about it despite the fact of a threat, and this gets her in trouble. In many fanworks that feature her, this ends up being her undoing and getting her in even more trouble.
- Green-Eyed Monster: Renko is implied to be jealous of Maribel's dream adventures and fully hopes to come along with her. Her jealousy is pretty much confirmed in Neo-Traditionalism of Japan.
While Renko felt a bit jealous, she hoped that somehow she too could see what Merry saw.
- Iconic Item: Typically seen with a book
- Leaning on the Fourth Wall: In Trojan Green Asteroid
"Right now I'm almost like the protagonist of a shooting game!"
- Leitmotif: While she doesn't have an official one, "Kid's Festival ~ Innocent Treasures" (ZUN's personal theme) is associated with her and Maribel in fanworks.
- "Greenwich in the Sky" would probably be the closest to one, given her ability to tell the time from the stars.note
- Ludicrous Precision: Her power is to tell the current time and place down by ludicrous accuracy.
- Overshadowed by Awesome: Merry's powers have been getting stronger. Renko's? Not so much if at all. If they have changed we don't know about it.
- Required Secondary Powers: Played with. Renko claims her ability can only tell the time in Japanese Standard, but Maribel points out that she should only need basic math to get other timezones.
- Schedule Fanatic: She can be late, but she'll always tell Maribel down to the second how late she was.
- Unusual Ears: As an Incredibly Lame Pun on her family name, Usami, Japanese fanartists sometimes draw her wearing bunny ears (usamimi).
Debuted in Eastern and Little Nature Deity
The Three Mischievous Fairies
- The Three Mischievous Fairies
Three fairies who love playing pranks on others and go treasure hunting, and often get punished for their practical jokes. Each fairy possesses a different power and are able to combine their talents. Though, while they are known for their teamwork, it is often haphazard, and they are often unsuccessful at pulling off their pranks. In Eastern and Little Nature Deity
and Strange and Bright Nature Deity
they lived in the Forest of Magic like Alice and Marisa, but as of Oriental Sacred Place
they've moved their home behind the Hakurei Shrine.
Tropes associated with the Three Mischievous Fairies:
- Badass Boast: Parodied when the fairies introduce themselves to Cirno and brag about how their powers make them unbeatable... at hide-and-seek. Cirno is, of course, genuinely impressed.
- Big Bad Wannabe: Their ambition is to terrorise humankind and prove that fairies, like the other youkai, are not to be taken lightly. The most they manage is to mildly annoy people with their pranks.
- Canon Immigrant: With Fairy Wars, they're the first expanded material characters to be put into a game.
- Defeat Means Friendship: Subjected to this twice - First in Great Fairy Wars where after being defeated by Cirno they either become subordinates or friends with her (depending on the route). In Oriental Sacred Place, they try to invoke this by challenging Reimu on reasoning that everyone that Reimu fights ends up becoming friends with her. It worked.
- Fisher King: By putting their home in a dead tree, they actually brought the tree back to life. This is actually pretty important, as the tree is part of the Gensokyo Border. Just as Yukari planned.
- New Year's Resolution: Every new year they plot to cause a major incident that will get Reimu's attention. Then they get drunk and forget all about it the next day.
- Power Nullifier: Reisen Udongein Inaba's abilities can cancel out all three of the fairies' powers.
- Resurrective Immortality: As embodiments of nature, they can't stay dead.
- Screwy Squirrel
- Spell My Name with an S: "Starsaphire" was presumably just a misspelling, "Sunnymilk" isn't much of a difference, but "Lunarchild" is trickier, especially since all three fairies tend to call each other by the first part of their names.
- Theme Naming: All three are named after heavenly bodies.
- Winged Humanoid: All three of them have wings that do not appear to be directly attached to their bodies.
- Prank-loving Sunlight
- Sunny Milk
Self-proclaimed leader of the Three Mischievous Fairies. Sunny can manipulate light via refraction. She is at her strongest during the day when the sun is out, but is weakened if the weather is cloudy.
Tropes associated with Sunny:
- Silent Moonlight
- Luna Child
Luna can manipulate sound, dampening it so she can sneak around. She is at her strongest when the moon is out, but is weakened if the weather is cloudy.
Tropes associated with Luna:
- Pouring Starlight
- Star Sapphire
The smartest member of the Three Mischievous Fairies. Star can sense any moving animate thing in a wide area, making her sort of a living radar. Unlike Sunny and Luna, she is unaffected by the time of day or the weather.
Tropes associated with Star:
Debuted in Perfect Memento in Strict Sense
Hieda no Akyuu
- Memory of Gensoukyou
- Hieda no Akyuu
The ninth reincarnation of the Child of Miare, who is born with the memories of each of the previous incarnations. She is the author of the Gensokyo Chronicle, an anthology of Gensokyo's history (published in Real Life
as Touhou's Universe Compendia
, Perfect Memento in Strict Sense
and Symposium of Post-Mysticism
), which she updates each time she is reincarnated.
Tropes associated with Akyuu:
Debuted in Silent Sinner in Blue
"H-How rude! There's nothing wrong with me! I just hit a little space debris, that's all!"
An apparently ordinary Moon Rabbit
who's gotten herself deeply involved in the events of Silent Sinner in Blue
. Reisen is just a literal pet name given her by the Watatsuki sisters, in honor of the other Reisen, their previous
pet, but her original name is unknown.
Commonly called "Reisen II" in Western fandom.
Tropes associated with Reisen:
- Little Bit Beastly: Lunar rabbit.
- Magical Eye: While it hasn't been confirmed, fanworks often depict her (and other moon rabbits) as possessing weaker versions of the other Reisen's Lunatic Red Eyes.
- New Meat: Recently recruited into the Lunar Defense Corps.
- One Steve Limit: This Reisen's name is written in katakana (レイセン), while Reisen Udongein Inaba's is written in kanji (鈴仙). Since they're "spelled" differently in Japanese, perhaps it might be appropriate to think of her as Raysen or some other homophone.
- Replacement Goldfish: Literally the replacement for the old Reisen who ran away.
- Telepathy: An inherent power of all moon rabbits, allowing them to share rumours and gossip between each other.
- Unwitting Pawn: She unknowingly draws the Watatsuki sisters into Yukari's plan when Eirin convinces her to go back to the Moon and warn the Watatsukis that Yukari was about to invade them. Though if Eirin hadn't warned them, then they would have been caught even further off-guard. The only difference is that because they were forewarned, both of Yukari's decoys were needed, whereas if they hadn't been, Yukari herself might have been able to successfully invade instead of ending up as decoy #2. Eirin was sending Reisen II to offer support against a rumored invasion that Eirin herself had spread the rumors for.
Watatsuki no Yorihime
- The Moon Princess Possessed by Divine Spirits
- Watatsuki no Yorihime
"Without a slap on the wrist? You are mistaken. Living on Earth is the worst punishment you can receive."
The younger of the Watatsuki sisters, Lunarian princesses and leaders of the Lunar Defense Corps. Yorihime is the more serious of the two. She has the power to channel gods, shared by Reimu, but due to a better work ethic she can use it far more effectively.
Tropes associated with Yorihime:
- Absurdly Sharp Blade: Sharp enough to cut Marisa's Master Spark in two!
- Action Girl
- All of the Other Reindeer: It's vaguely implied that the other Lunarians distrust her due to her power. Helping Yorihime solve this problem, by showing Lunarians that other people like Reimu can also summon gods, seems to be one objective of Eirin's plan.
- It doesn't help that the sisters' mentor betrayed Lunarian society, and they put only token efforts into tracking her down.
- All Your Powers Combined / Summon Magic: Her fighting style relies on summoning gods into her body, letting her switch between powersets to fit the situation. She's shown the following:
- Badass Bookworm
- Boring Invincible Hero Antagonist: The main criticism against her.
- According to ZUN, this was intentional, and the reason why she's only in the manga and not in any of the games.
- Everything's Better with Princesses
- Evil Counterpart: To Reimu, though the "evil" part is debatable. They both have the power to channel the gods, and despite being tasked to defend their race are oddly friendly towards their supposed enemies (earthlings and youkai respectively). Also like Reimu she has reputation issues among her own people.
- Katanas Are Just Better
- Lady of War
- Leitmotif: Shares "Watatsuki's Spell Card ~ Lunatic Blue" with her sister.
- New Powers as the Plot Demands: No matter what kind of attack the Gensokyo team throw at her, Yorihime is always able to summon a god from the Shinto pantheon with exactly the right kind of power to counteract it.
- Not So Invincible After All: In Inaba of the Moon and Inaba of the Earth Chapter 26, she gets knocked out by accidentally falling into one of Tewi's Pit Traps.
- OC Stand In: Izunome, the goddess Yorihime summoned to defeat Reimu, is a character whose name is only mentioned once in the Kojiki, so nobody knows what kind of god she actually is. In this story, conveniently enough, she's the patron goddess of miko.
- Proud Scholar Race Girl
- Sibling Yin-Yang
- Space Elf
- Surrounded by Idiots: The "soldiers" she is in charge of are clueless teenage-like bunnygirls who run from the first sign of danger if the Watatsuki sisters are not present.
- Training from Hell: What she subjects Reisen and Reisen to during her visit to Eientei.
- Tsundere: Loudly insisted to Toyohime that she couldn't go to Earth to visit Eirin because she had to stay behind to defend the Moon, but ended up going anyway out of admiration for her former teacher.
- Unwitting Pawn: Despite her "winning", she got completely played by the parallel plans performed by Yukari and Eirin in Silent Sinner in Blue.
Watatsuki no Toyohime
- The Moon Princess Connecting Mountain and Sea
- Watatsuki no Toyohime
"It's quite impossible for the creatures here to live without sin. Simply living and dying on earth is sin enough."
The older of the two princesses, Toyohime has a more carefree personality than her sister, though she can get serious too. She has "the power to connect sea and mountains", which allows her to move things between the true Moon, the false Moon and Earth.
Tropes associated with Toyohime:
- Big Eater: When it comes to peaches, at least. In Inaba of the Moon and Inaba of the Earth she eats a whole bowl so fast that Reisen couldn't even see it!
- Everything's Better with Princesses
- Evil Counterpart: Arguable case with Yukari, as Toyohime can also manipulate boundaries, although her ability may be restricted in scope to the lunar capital. The "evil" part is also debatable.
- Fantastic Racism: As she narrates to Yukari, Lunarians look down on the people of Earth for being "impure" and tainted by sin. While true, this doesn't really excuse that many of the deaths and struggles on Earth were by their own hands, from trying to control humanity with Youkai in past, to starting wars over prized treasure in the present.
- To put this in context, in Shinto belief impurity is the product and source of all evil and misfortune, and the greatest source of impurity is death. Taking this to its logical conclusion, humans are only mortal because of the earth's impurity slowly poisoning them, and as the moon has never been touched by death it acts as a Heaven-like realm that turns its inhabitants into ageless superbeings. Allowing normal humans in would eventually taint the moon until it lost this property. As she says, the crime is living on Earth and the punishment is living on Earth.
- On the other hand, Toyohime seems oddly okay with Earthlings on a personal level (at least, Earthlings who aren't Yukari), to the point where she once let a human live on the moon for three years in secret, and attempted to bring an Earth rabbit home as a pet.
- I'm Taking Her Home with Me!: Repeatedly tried to take an Earth rabbit back to the Moon with her when she visited Eientei.
- Leitmotif: Shares "Watatsuki's Spell Card ~ Lunatic Blue" with her sister.
- Paper Fan of Doom: One that can "instantly purify" things at the atomic level! ZUN says the reason it looks like a paper fan is "I didn't explain the weapons to Aki Eda, so the depiction was super sloppy (lol)."
- Space Elf
- Supernatural Gold Eyes
- Supernormal Bindings: Carries around rope woven from "femtofiber" that can bind practically everything, up to and including gods.
- Trademark Favorite Food: Peaches, which leads to her sometimes being paired with Tenshi.
- The logic behind this is that peaches are the cliche "heavenly" food in Far Eastern cultures, much like harps are associated with angels in the West.
- Unwitting Pawn: Also got completely played by the parallel plans performed by Yukari and Eirin in Silent Sinner in Blue.
Debuted in Wild and Horned Hermit
- The One-Armed, Horned Hermit
- Ibaraka-Sen/Ka-Sen (real name Kasen Ibaraki)
"The only people who live on the surface are good men, saints... and True Villains."
A somewhat mysterious hermit with an association with the Hakurei Shrine and some past connections to Former Hell, as well as to Suika and Yuugi. Her right arm is covered entirely in bandages and has a number of magical properties, such as appearing to be made of smoke and being able to destroy evil spirits. She can also talk to animals and keeps a menagerie of rare and legendary animals at her home on Youkai Mountain. Widely considered by fans to be an oni.
Tropes associated with Kasen:
- The Alcoholic: Despite whatever stereotypes one might have have Hermit Gurus, she loves her sake, and is often bragging about its strength ("enough to drink even an oni under the table"). In chapter 16, she surprises Marisa by using a 2 liter drinking cup, and tells Sanae that she can't stop drinking, although she has her reasons...
- Like Suika and Yuugi, she owns an alcohol-related magic item named after her. In her case, it's the Ibaraki Box of a Hundred Medicines, which turns any sake poured into it into an elixir that cures any illness and heals any wound. At the cost of turning the drinker into an oni, either mentally or physically depending on what it heals. Was anyone still doubting that she's an oni?
- Ambiguously Youkai: Refers to herself as human, but she's based on the oni general Ibaraki-douji, she wears shackles like the other oni characters in the series, her hairstyle covers where an oni would have horns, and she has some sort of past with Suika. Smaller hints that Kasen isn't what she claims appear fairly often, like having a Sneeze Cut to her when people start talking about youkai. There are enough hints that she's a youkai that having her turn out not to be would be a shocking twist at this point.
- This is further established by Suika in chapter 16 where she wonders why Kasen continues to pretend to be a hermit, and in chapter 18, Komachi, who certainly would know, outright says that she's pretending to be an hermit to Kasen's face, who doesn't deny it.
- Artificial Limbs: While she claims that her bandaged right arm is just scarred, when Reimu squeezes it there's nothing but black smoke underneath. She seems to be looking for her real arm so she can reattach it.
- Bad Liar: Tends to become visibly nervous or agitated when she's hiding the truth, though most of the time the other characters either don't notice or assume she's offended.
- Bandage Babe: Her right arm isn't merely covered with bandages, her right arm is, for all intents and purposes, smoke covered in bandages.
- The Beastmaster: Her stated power is the ability to guide animals. This includes speaking to birds, obscure zoological knowledge (including poison remedies, and how to alter or reverse the transformation of animals into youkai), and keeping things like baby dragons, giant rocs and guard tigers as pets.
- Blue and Orange Morality or White and Gray Morality: Despite almost certainly being a disguised youkai herself, she generally takes the side of humans. In fact, she protests more for humans and animals than she does for youkai throughout Wild and Horned Hermit. Both tropes are hinted by Yukari in Chapter 14.
- Buxom Is Better: A lot of fanartists have been drawing her this way.
- Chained by Fashion: Has a manacle on her left wrist with a small chain attached, leading to speculation that she's a secret oni, because the other oni in the series both also have manacles on their arms. Obviously, she's missing the manacle on her right arm because she's missing her right arm.
- The Corruption: Chapter 16 introduces us to Kasen's Ibaraki Medicine Box. Any sake drunk from it will grant you Super Strength and cure your ailments, but it will also change your personality into that of an oni's. In addition, if you drink it while injured and it heals you, you will literally become an oni.
- Dark Secret: Heavily implied to be a youkai (most likely an oni) masquerading as a human.
- Deader than Dead: Her smokey right arm doesn't just kill spirits, it removes them from the cycle of reincarnation entirely. Komachi is not happy about this.
- This is referred to as Nirvana-esque Enlightenment. Komachi is not happy because those evil souls don't deserve the short-cut off the Reincarnation Cycle.
- Defeat Means Friendship: Notably averted. She is the only character who's friends with Reimu who has not fought her. Her status as a hermit seems to have given Reimu an unusual amount of trust in her.
- Detachment Combat: She can detach her bandaged Artificial Arm and use it to grab things when it's separated. In addition, it's implied that her original arm is still alive somewhere and can move around on its own.
- Enlightenment Superpowers: A more accurate description of what's meant by "hermit" in this setting.
- Flower Motifs: Strongly associated with roses, as evidenced by her clothing and the meaning of her name.
- Handicapped Badass: It's all but outright stated that she lost her arm. And being a hermit, she has to fight shinigami on a regular basis.
- Hermit Guru: She's classified as a hermit, which means that she's supernaturally strong, long-lived and youthful, but is also often secluded and must do things like recite proper sutras each day and perform acts of piety, or instantly lose her abilities and her immortality.
- In practice, this involves Komachi the shinigami repeatedly popping in to tell her what she has to do. Although you might expect Komachi to hold a grudge against her for the improperly destroyed spirits and choose not to tell her, that hasn't happened and they maintain a mostly-friendly relationship, snarking aside.
- In Chapter 16, Suika claims that she's not actually a hermit and is only pretending to be one, and Komachi does the same on Kasen's presence in chapter 18. Kasen doesn't deny it.
- Light 'em Up: Kasen has shown the ability to create balls of light that last for long periods of time.
- Meaningful Name: Apparently drawn from Ibaraki-douji, an oni who was either the lieutenant or wife of Shuten-douji (on whom Suika is based).
- Meaningful Rename: Her real name (in Eastern order) is Ibaraki Kasennote , but nowadays she goes by "Ibarakasen". Given that she's a hermit who dresses in a rose theme, Ibarakasen ("Wild Roseflower Hermit") arguably straddles the line between Meaningful Name and Red Baron.
- Her Name Really Is Kasen / Steven Ulysses Perhero: Her pseudonym is very close to her real name, and both can be shortened to "Kasen" (though spelled with different characters).
- My Species Doth Protest Too Much: She dislikes the status quo of "youkai attack humans and cause fear, humans exterminate youkai" (even if it's mostly non-lethal nowadays) and believes that youkai should be able to deny their original purpose and choose their own. This may sound good, but Eiki Shiki's concerns about the characters' sins in Phantasmagoria of Flower View seemed to be mostly about the minor ways in which they had drifted from their purposes...
- Mythology Gag/Leaning on the Fourth Wall: In her first appearance she recites Miyako no Yoshika's work, as her base character, Ibaraki-douji, was deeply impressed by said author's work. Yes, this is the same person who is the base for Yoshika Miyako in Ten Desires.
- Pay Evil unto Evil: Prefers to destroy vengeful spirits rather than wait for them to repent. Possibly a case of Eviler than Thou as well.
- Pocket Dimension: Her home can only be reached by following a highly-specific path, and has its own climate. She can even change the path if someone discovers it. Word Of God says this is the same technique the Lunarians use to hide the Lunar Capital.
- Rocket Punch: Shown to be able to do this in one of the omake comics in the collected volumes.
- Rose-Haired Girl: To go with the general rose motif. A possible case of Ascended Fanon — fanartists started drawing her with pink hair after the first chapter was released, and she wasn't confirmed to have pink hair until the second chapter was published with color pages.
- Something about a Rose: Has a very prominent rose motif.
- Supernaturally Delicious and Nutritious: Hermits are the favorite food of youkai. Eating one can cause a youkai to ascend to a completely new level of power. And if an ordinary animal were to eat her, they'd become a youkai on the spot. Of course, that's not exactly easy to do, since she's extremely powerful due to being a Hermit.
- The Unfought: One of the few beings who hang around the Hakurei Shrine and consider themselves friends to Reimu without getting in a fight with her first.
- What Could Have Been: Word Of God states she was considered for the position of Extra Stage Boss of Ten Desires. Fans have of course made their own version of what could have been.
- Wound That Will Not Heal: According to Kasen, the miracle oni healing sake doesn't heal her arm; however, if she were to stop drinking it, her arm would "completely rot away."
- Which takes on a somewhat different meaning when you realize that her arm isn't even attached to her anymore. She's got a perfectly preserved arm sitting around somewhere.
Debuted in Forbidden Scrollery
- Bibliophile with Deciphering Eyes
- Kosuzu Motoori
"We'll cross that bridge when we come to it. And when that time comes, I'll come to you, Miss Reimu!"
Daughter of the human village's local book renter and friend of Reimu and Akyuu, she has the ability to read books in any language, though she only gained this ability shortly before Forbidden Scrollery
begins. She's a enthusiastic bookworm who loves to collect books for herself as well as lend them out, even though the books she collects are supernatural and potentially dangerous in nature. This makes her a liability in Reimu's eyes, but Kosuzu has faith that Reimu will always come and rescue her. She looks up to
Mamizou without realizing that she's not human.
Tropes associated with Kosuzu:
- Addictive Magic: She is getting more and more attracted to her books, summoning a low-level version of the Night Parade and creating tsukumogami. She's keeping it to one day per month to avoid summoning something too big or attracting unwanted attention, but she still is quite excited to do so because she can "feel the youkai energy."
- Why is this a bad idea? The Night Parade is the Japanese equivalent of The Wild Hunt. It's also Mamizou's Last Spell in Hopeless Masquerade, and an annoying one at that.
- Berserk Button: DO NOT DAMAGE THE BOOKS!
- Collector of the Strange
- Comically Missing the Point: Kosuzu tends to misinterpret what she hears about real world events, like how the fall of the Soviet Union and the Berlin Wall must mean that the outside world has a lot of construction defects.
- Cute Bookworm
- Fangirl: Of Mamizou, though she's unaware of her being a youkai.
- Fearless Fool: Has no concern that she might accidentally summon an antagonistic youkai or Eldritch Abomination because she's sure Reimu will save her.
- Friend to All Children: Reads stories to village children who are too poor to own books.
- Girlish Pigtails
- Hair Decorations: Wears bells in her hair to fasten her pigtails, which also matches her name (Kosuzu meaning "little bell").
- Historical-Domain Character: She's most likely based on Norinaga Motoori, a prominent 18th-century scholar who is most notable for deciphering the Kojiki, the oldest extant chronicle in Japan. Kosuzu's given name means "little bell", which is probably a reference to Norinaga's hobby of collecting bells.
- Meganekko: Reading glasses, like Luna.
- Mook Maker: Her Night Parade book creates tsukumogami, and Mamizou encourages this because the Tanuki can recruit them.
- Omniglot: She has the magical ability to read any written language, including dead languages spoken by no one.
- Sprouting Ears: Does this in a chapter of Forbidden Scrollery when she gets angry, invoking the image of a hissing cat.
- Squee: Reacts like this to Mamizou playing Mysterious Stranger.
- Summon Bigger Fish: In order to get rid of a youkai bookworm, Kosuzu summoned a smoke youkai to get rid of it, then got Reimu and Marisa to get rid of the smoke youkai (blaming its appearance on the bookworm).
- Summoning Ritual / Summoning Artifact: She is capable of releasing at least some of the youkai in her books, but not controlling them (other than tsukumogami, more or less). She can, however, direct Reimu and Marisa at them if things get out of hand.
- Tome of Eldritch Lore: "Youma Books". She collects them; some are merely books written by youkai or magicians (either to themselves or others of their kind), while others are reminders that they existed in hopes that Clap Your Hands If You Believe will apply when someone reads them, while others still are youkai or have youkai sealed inside them. Her ability allows her to read them regardless of what ancient forgotten language they may have been written in, but if she accidentally summons something unfriendly, she's sure Reimu can handle it.
- She even has one of the original copies of the Necronomicon.
- Unwitting Pawn: To Mamizou.
- Vague Age: Like Reimu and Marisa, it's unclear exactly how old she is, but she seems to be a few years younger than both of them, or at least about the same age as Akyuu's current incarnation.
- Whole Costume Reference: Her "incognito" outfit in chapters 10-11 of Forbidden Scrollery is the same one worn by Kosuke Kindaichi.
