MARISA Marisa is an outgoing and informal person. Hieda no Akyuu states that her personality is condescending, but she has a sophisticated side to her that tends to be interesting. She socializes with many inhabitants of Gensokyo and is friendly to both human and non-humans individuals. She's quick to act if she hears or sees anything interesting, sometimes doing dangerous things to satiate her interest at the time like when she follows an eagle on a whim in the middle of a blizzard. She speaks in an informal manner and typically uses the sentence ending particle da-ze~ (ぜ). REIMU Reimu is defined as unusually easygoing, lacking any sense of danger, and being carefree. She is described as simpleminded, always showing her true feelings and acting on whatever ideas she thinks, She can also be emotional and noisy, and her presence is well known wherever she is, but she can also merge into her surroundings quite easily when necessary. She is portrayed as someone simple who passes her days sweeping the shrine grounds, drinking green tea and lazing about DAIYUSEI Daiyousei (大妖精 Daiyōsei) is a greater fairy who lives by the lake around the Scarlet Devil Mansion. Like other fairies, she is cheerful and mischievous, simple and emotional. And she’s cirno best friend CIRNO It an ice fairy. While she is described as a weak boss in the Touhou series, her powers are not to be underestimated, and that is implied to be so in Phantasmagoria of Flower View by Eiki Shiki. Her personality is childish and rather incompetent, as you and many others might expect from her appearance. Her intellect is not very developed. She's just a child. To Reimu and Marisa, she's nothing more than a plain idiot. She think to be the most strongest of Gensokyo but it very far to be the case She likes playing tricks and often toys with frogs. She freezes them instantly, then watches them revive as they thaw in the water. Youmu Konpaku is one of the stranger entities in Gensokyo, part human and part phantom at the same time. Her two halves are not intermixed like one would expect from a crossbreed, but actually exist in physically separate bodies. Youmu has a straightforward and focused personality, which complements her sword fighting skills well. However, her personality conflicts with that of her master, Yuyuko Saigyouji, who is very whimsical and playful in nature. Still, she serves Yuyuko as best as she can, tending to the gardens in Hakugyokurou and following her orders. Youmu commonly wields two blades at once, having studied under her predecessor, Youki. The longer blade, called 楼観剣 (Roukanken) - Lookout-Tower Sword, is said to be able to kill ten ghosts in one swipe. The shorter blade, 白楼剣 (Hakurouken) - White Tower Sword, is able to cleave through a person's own confusion. However, not much is known about her particular style of sword fighting or about her parents. What is known is that Youki, also a servant of Hakugyokurou, had begun training a very young Youmu possibly as a child, when he suddenly disappeared one day, leaving her style incomplete and presumably causing her to teach herself. No one currently knows his whereabouts. YUYUKO Yuyuko Saigyouji is the ghost princess of Hakugyokurou, the netherworld of the "formerly-living", but was once a living human. Long ago, after her death from suicide, her body was used to place a seal on the Saigyou Ayakashi, a dangerous youkai cherry tree, to stop it from killing innocent humans. She has the power to invite mortal souls to death, and those souls who perish this way wind up in Hakugyokurou rather than Heaven or Hell. Though it might seem dangerous for such a whimsical, seemingly impulsive personality to wield such a terrible power, Yuyuko appears to have a strong sense of responsibility regarding her power, and never uses it recklessly or out of spite, nor does she use it as a weapon. Ironically, it was this power that drove her to kill herself in the first place. Humans fear Yuyuko because of her fearsome power and a general fear of the supernatural, but she is very cheerful and friendly. Unlike many ghosts, she resembles a living human, and her playful, good-humored personality, otherworldly beauty, and courtesan charm can have a disarming effect. She often makes bizarre and apparently nonsensical remarks and sometimes seems to overlook the obvious, leading to her characterization as an airhead or a ditz. However, at other times, she will reveal an extremely cunning and perceptive side and will also sometimes display an extraordinary level of knowledge. She seems to never take anything too seriously, though, and she loves to tease her straight-laced and eager-to-please assistant, Youmu, who is her opposite in many ways. Probably originating from the term "hungry ghost", she is also known for her incredible appetite and seems to have a food-related metaphor for any situation. Yuyuko is truly "dead and loving it." REMILIA While she tries to cultivate the image of a mysterious and frightening vampire aristocrat, she is surprisingly polite. Her long lifetime has only served to make her prone to boredom and as a result she prizes anything she finds novel, frequently indulging her own childish whims in order to create entertainment for herself. In Silent Sinner in Blue she allows herself to be manipulated by Yukari Yakumo, simply because the alternative would have been boring. The other residents of the Scarlet Devil Mansion spend much of their time catering to Remilia's odd whims (including numerous parties), though she does make an effort to appreciate and respect their patience. Remilia is respected by most youkai of Gensokyo and so she's said to have a charismatic personality. However, in reality this is only because of the fear they have for her kind. While she can act in an overblown and grandiose fashion, she usually only does it during incidents or for important matters. Otherwise, she tends to exhibit childish behavior. She enjoys novel things and isn't above playing along in silly games FLANDRE In Embodiment of Scarlet Devil, she is described as being quite strange and eccentric, which makes it difficult for others to understand her. She's also described as being "normally docile" and generally pleasant to be around, but somewhat of a loose cannon if left unwatched. In Bohemian Archive in Japanese Red, it's suggested that she isn't very good at talking to other people, though she can get rather sassy and uppity when talking with her sister. Her friendship toward humans is very low. In Foul Detective Satori, her attitude was particularly impolite and informal, speaking in a very casual tone and generally doing as she wished without consideration of consequences, although she stopped short of seriously injuring anyone. In Sunken Fossil World, she appeared to only care about "destroying the indestructible" when facing off against Yuuma Toutetsu, although she did display a willingness to work with Okina Matara, insofar as it let her have some fun. Until the time when she met either Marisa Kirisame or Reimu Hakurei in Embodiment of Scarlet Devil, she claimed to not have seen any humans other than when they were prepared for a meal, although it's left vague as to whether that was her idea of a dark joke. During the events of Sunken Fossil World, however, she left the grounds of the Mansion for an extended period of time of her own accord to fight Yuuma Toutetsu, marking her first major departure from the grounds of the Mansion since her introduction. Abilities As a vampire, Flandre possesses superhuman capabilities just like Remilia Scarlet, such as enhanced physical strength, with the destructive power of oni and the nimbleness of tengu, as well as a vampire's bodily and regenerative ability. She can swing an oversized sword, though not as quickly as she would like to. Sakuya personality seems perfect and elegant, being a fairly serious person overall, as befitting of a maid. Although due to the nature of the mistress of the house, it is arguable whether she serves the role of a maid or a babysitter. Sometimes she shows a more spaced-out and airheaded side, and can be surprisingly unreliable. She's polite and pleasant towards to her mistress Remilia Scarlet and those she's close with, such as Patchouli Knowledge, while being less formal with other people. REISEN  Reisen is described as changing her personality completely to match her circumstances. Ordinarily timid and sometimes showing a scatterbrained side, she can be both carefree and crazed, and is a different person in battle. Indeed, ZUN states that her uniform is to give the impression of an inconsistent personality. As she is not originally from the Earth, she has never been friendly and cannot get along with humans very well. Watatsuki no Toyohime, when commenting on Reisen's abandonment of the moon, states that that she was both self centered and cowardly, poor traits for a soldier in the Lunar Defense Corps. Eiki Shiki additionally affirms this by stating Reisen's sin is that of selfishness due to abandoning her allies, something Reisen states she is "earnestly trying her best" to fix. Later on in Forbidden Scrollery, she is seen peddling medicine for the Human Village, and invented a device to repel rats to assist with the Human Village's rat problem, without input or permission from her master Eirin Yagokoro. Reisen states that because her and the residents of Eientei are outsiders to Gensokyo, they should aim to be "productive members of society", as isolating themselves by aggravating others would be a bad idea. TEWI Tewi is described as being more like a fairy than youkai, with being childish in her way of speaking and acting; specially with Reisen, who is the target of her pranks and she hides from the moon rabbit to annoy her. Despite her childish appearance, she is one of the oldest Youkai in Gensokyo who has lived for more than 1,000 years before the first Gensokyo Chronicle was written (if she really was the White Rabbit of Inaba, she would have existed since the early of 8th century) and is very wise and cunning. It is also noted that she doesn't care about selling her own species to humans if she knows that they will abandon them; which would make the rabbits become youkai too.Tewi is a very lighthearted and playful youkai, and is known to lie at times. In Phantasmagoria of Flower View, she even tries to swindle Aya Shameimaru out of some pocket change. EIRIN Eirin Yagokoro is a genius of medicine from the Moon, and is able to create the Hourai Elixir. She is living in exile in Gensokyo after choosing to stay with and devote herself to Kaguya Houraisan on Earth rather than take her back to the Moon. She was a very well-known figure on the Moon, having not only been instrumental in the founding of Lunar society with Lord Tsukuyomi, but also being its leading medical mind and the person in charge of the Moon's emissaries to the Earth. It seems that now Eirin has begun using her knowledge of medicine to act as Gensokyo's premier pharmacist, selling medicines at Eientei ranging from sleep aids to various cures. She is generally a fairly pleasant person and is devoted to serving her best friend, Kaguya, but she does not suffer fools gladly, and because of her incredibly high intelligence, she can come across as conceited, impatient, and condescending at times to those not sharp enough to follow her explanations immediately. Story During the events of Imperishable Night, Eirin attempted to seal the passage between the Earth and Moon, which becomes open during full moons, by casting a spell that would seal the Earth inside a chamber (similar to a Chinese folktale about a paradise found inside a pot). She only meant to do this to protect both Kaguya and Reisen so that the emissaries coming from the Moon wouldn't be able to reach them, but this did not go unnoticed by the various Youkai in Gensokyo who enjoy the moonlight. Kaguya Houraisan (蓬莱山　輝夜 Houraisan Kaguya) is an immortal Lunarian who was once a princess of the Lunarians of the Lunar Capital on the Moon. She had Eirin Yagokoro create the Hourai Elixir with the help of Kaguya's power to control eternity which lead to her being exiled to Earth. After liking her life on Earth, she and Eirin choose to not go back to the Lunar Capital and resided for thousands of years in Eientei within the Bamboo Forest of the Lost that is now in Gensokyo. Kaguya first appeared as the true Stage 6 boss and one of the main antagonists of Imperishable Night. Personality She is also described as haughty and relatively wild, often sneaking out to visit the human village. She apparently is refined in the art of conversation, but her vocabulary is a bit dated. Abilities Manipulating eternity and the instantaneous Eternity is namely immutability, and it can be said that eternity rejects all change. Things that possess eternity indefinitely do not change, and also cannot be interfered with by things outside of themselves. By using her ability on everything in Eientei, she made it so that living things stopped aging, objects would never break, and food would never spoil.[5] Additionally, beginning from when Kaguya came to Gensokyo, she lived hidden away for a thousand years in the interior of the Bamboo Forest of the Lost without anybody knowing about her. Also, the pure Japanese-style mansion in Eientei can be seen not to have worn out at all, which can be said to have been due to this ability of eternity. After the Eternal Night incident, Kaguya removed the spell of eternity from Eientei, causing objects to break as normal, living things to age again, and food to spoil if not eaten in time. Incidentally, as the Hourai Elixir made by Kaguya's ability of eternity is something that makes the consumer have a "body that rejects all change," it can simply be said to be a kind of maximised, self-healing ability (due to this, it is said that the entire body can recover from just a single hair left intact, as shown in the case of Fujiwara no Mokou). In the last spell card "End of Imperishable Night" which used this ability, it destroyed Reimu Hakurei and the others' spell of eternity, and forcibly called for dawn (End of Imperishable Night -Rising World-, where "Rising World" was a homophone to "dawn" as "yoake" (夜明け)). On the other hand, Kaguya, in being able to manipulate the instantaneous, is able to alter the needed "instants" and make them her own time. However, whatever she gathers together—since it is made up of many "unrecognisable instants" that cannot be changed—has no means of being known about. For this reason, in manipulating the instantaneous, Kaguya is able to spend "time the same as others'" and "time different from others'" simultaneously. Hieda no Akyuu presented this as "having parallel timelines at the same time." In the nineteenth chapter of Silent Sinner in Blue, as the instantaneous is the smallest unit of time, time is able to accumulate countless instants. Watatsuki no Toyohime explained that to see time as continuous is due to the inability to recognise the instant. Since her ability can be said to be the ability to manipulate "complete stop = eternity" and "extreme speed-up = instant", Akyuu also summarised it as an "ability to manipulate time". This seems very similar to Sakuya Izayoi's "ability to manipulate time." Fujiwara no Mokou (藤原 妹紅) is an immortal human capable of manipulating fire who obtained immortality after drinking the Hourai Elixir over 1,300 years ago. After Mokou's aristocrat father was humiliated from being unable to fulfill Kaguya Houraisan's impossible request, Mokou stole and drunk the Hourai Elixir from an Emperor's men as a way to get revenge on Kaguya who had left it as a gift for the Emperor. Over 1,000 years later, she now protects humans from youkai and guides anyone outside of the Bamboo Forest of the Lost when they get lost in it, while also having a rivalry with Kaguya. Mokou first appeared as the Extra Stage boss of Imperishable Night then became a playable character in Urban Legend in Limbo and Antinomy of Common Flowers. Personality Perhaps due to being ostracized for so long, Mokou is a loner by nature and chooses not to socialize with humans or youkai. She escorts lost humans she finds within the Bamboo Forest of the Lost, giving herself a job similar to that of a bamboo forest guide, and even then after escorting between Human Village and Eientei, she departs without saying a word. Nevertheless, to those whom she's acquainted with, she speaks bluntly and with lively personality. In Imperishable Night's extra stage, for example, she was easily roused and goes on a rant about how annoying Kaguya is. Not much else is known about her as she doesn't really talk much to anyone. Her style can be described as masculine - she wears a dress shirt with suspenders and karusan (a type of hakama typically worn by men) tied at the waist, rather than above the waist as is standard for women's hakama. Although she used feminine speech patterns in Imperishable Night, beginning in Urban Legend in Limbo, her speech is typically masculine as well. She undertakes the duty of escorting people in the Bamboo Forest of the Lost. Although this may allow her a wider opportunity to socialize with other people, she still remains very reticent about herself. For example, when asked about her past, she doesn't answer with anything other than "I'm an ordinary health maniac who runs a yakitori stand" (it is unclear whether she truly does run a yakitori stand). However, she seems to happily listen to others' talking. Thus, even if someone doesn't lose one's way, it would be possible for her to be enlivened by a conversation. She presently seems to be very content with her life contrary to being commonly thought of having a pessimistic lifestyle. With an unaging, undying body, she and Kaguya Houraisan kill each other every day, and the text of Imperishable Night even emphasizes this with the line "and she is alive to enjoy it, how magnificent!"

After the Imperishable Night incident, Kaguya reisen eirin and tewi decide to create a festival for catching a mysterious youkai
