PEOPLE WHO TRY TO RESOLVE THE INCIDENT ALICE Alice Margatroid is one of the few people known to live within the Forest of Magic. She's a Magician known primarily for her skillful use of dolls, as well as being a loner. She gets in many fights with Marisa but they are somewhat acquaintances, sharing many of the same interests and even teaming up during Imperishable Night and Subterranean Animism. 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 YUKARI YAKUMO An often seen and referenced character, Yukari Yakumo is the youkai of boundaries. She was first introduced in Perfect Cherry Blossom as the sleepy mistress of Ran Yakumo. During Imperishable Night, Yukari teams up with Reimu to find those responsible for the fake moon. In Immaterial and Missing Power, she actually sings her way from battle to battle, stealing everyone's sake, wine, and brandy, even right from the shrine's altar. However, this is all part of her strategy to save the day. Story Over a thousand years ago, Yukari organized an army of youkai and led them in an invasion of the Moon. The youkai were subsequently routed by the Lunarians, who possessed superior technology and magic, and was forced to retreat to Earth. Since that time, no youkai have attempted to expand their territory beyond Gensokyo. While some speculate that Yukari organized the invasion out of selfish hunger for territory and power, others believe she did it to teach the youkai a lesson about starting wars of conquest; namely, that it was a bad idea. About a thousand years ago, Yukari met and became friends with a human girl named Yuyuko. After Yuyuko died, Yukari continued to be friends with Yuyuko's ghost, although Yuyuko gradually forgot who she had been and why she had died. In Perfect Cherry Blossom, Yuyuko requested that Yukari use her power to weaken the border between the Netherworld and Gensokyo, Yukari obliged. She knew Yuyuko's plan to make the Saigyou Ayakashi bloom could never succeed, but was too busy sleeping to say or do anything about it, or to put the border back to normal after everything was finished, which put her on a collision course with the heroines. Yukari is known for being a very youkai-like youkai who sleeps all day and lives for the enjoyment of life. Though she rarely leaves her house, she's well-connected and is acquainted with most of the most powerful youkai, such as Suika and Yuyuko, as well as anyone having anything to do with the Hakurei border or outside world (Reimu and Rinnosuke). She's possibly the most powerful youkai in Gensokyo, and has a tendency to toy with her opponents rather than use her full power from the start. She often has a great deal of insight and understanding about whatever happens in Gensokyo, and possesses considerable intellectual prowess as well. Though she seems flaky and unreliable most of the time, when the safety or security of Gensokyo is at stake, she won't hesitate to get involved, even if it means using others to do the work for her. For example, in Scarlet Weather Rhapsody, she treats Tenshi Hinanawi with much hostility after finding out the plot of the Heavens. She could easily be either a villain or a heroine, depending on her whims. YOUMU 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." PEOPLE WHO TRY TO TRIGGER THE INCIDENT 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.

In a night of Gensokyo eirin a servant and doctor of the princess kaguya having shooting a arrow in direction of the moon, making a illusion of fake moon by order of her mistress kaguya putting everyone at Gensokyo in the chaos the Imperishable Night incident started, making Gensokyo in a eternal night but marisa and alice who haved pass by the human village in meeting keine, on the advice of her last marisa and alice going into the bamboo forest of the Lost, after a fight between marisa and reimu they haved discover a strange manor in the bamboo forest of the Lost with reisen the rabbit youkai gardian of the manor, so reimu marisa alice and Yukari are okay to be splitting in two group the group of alice and Yukari countain reisen meanwhile reimu and marisa continue in the hallway and meeting tewi the rabbit girl youkai
