Touhou Doujin: Grimoire of Dawitsu
Lunatic Lunar Rabbit, Reisen Udongein Inaba
Reisen Inaba is a rabbit youkai who hails from the moon. As you'd expect, rabbits from the moon are quite different to rabbits from earth, and have undergone parallel evolution in certain ways. For example, both earth and lunar rabbits have long ears, but earth rabbit ears look organic whereas lunar rabbits... look like buttoned-on strips of bacon.
Anyway, she has a frightening ability- the ability to induce insanity. Fortunately, she isn't a megalomaniac, and doesn't use her abilities on a large scale. Yutaka, to the next section!
Personality
Reisen is actually a really calm character. The kind of character you associate with the ability to drive people mad is... well, a mad one. But this rabbit is a chilled out one, and she doesn't seem to freak out about much at all. In fact, getting into a fight with her is pretty difficult, because she simply isn't the kind of girl to throw herself into battle. She's just... well... cool, to be honest.
She is a deserter from some kind of war on the moon, so if there is one way to confront her, it is to mention her past cowardice. You never know, it might work... but then again, she probably won't bother expending energy on you, she knows better. The only time she actively attacked someone in Gensokyo was during the 'Fake Moon' incident, where she put her all into defending her mistress, Kaguya Houraisan. But apart from that, she's relatively hard to observe in action.
Notes on Mimicry
Should you ever manage to confront her, you've reached a golden opportunity. She uses very simple long range hypnosis using her special 'red eyes of insanity'. The way this works is... well, have you heard of the saying 'Looking through red-tinted spectacles'? Well, it's a similar concept. She uses her imagination to come up with the most insane or illogical things she can think of, and this becomes her 'red spectacle' image. She then superimposes this image onto the victim's mind by staring them in the eyes. She does this with both hypnotic technique and psychic suggestion (see instructional video 'Inception' to see how easy it is to send your mind to someone else's).
Essentially, during Danmaku sessions, she uses this ability to confuse the opponent as to where the danmaku actually is. The answer is it probably is nowhere near you- the bullet's image is the only thing you're seeing, but you're so convinced that it's there that when it hits you, it hurts like an actual bullet hit you. The mind is a huge part of reality, something that many Youkai take for granted. Ultimately reality is determined by what we observe- no matter how much experimental evidence is gathered, it's all ultimately perception on our part. And Reisen knows that better than anyone else on earth.
From what I hear Reisen is actually not that unique to the lunar rabbits, and a lot of them have similar powers. If that's the case, I must make it a point to never visit the moon.
When it comes to actual formation of Danmaku, she doesn't actually worry about where she shoots, and focuses entirely on the opponents mind. However, she shoots from her fingers, and one can quite easily imitate the technique. Simply make a 'pointing' shape with your fingers, aim, and shoot, moving your hand as it's recoiling from firing the projectile. If you did it right, a bullet shaped like a crayon should appear. And before you say, no, they aren't shaped like suppositories. Yutaka, anything further to add?
Typist's notes: My boss is very protective of the shape of Reisen's bullets. Perhaps he just admires her so much that he can't take part in debauched humour at her expense.
Actually, my boss really likes a set of cosplay outfits known as bunny-girl outfits, even forced me to wear such a suit one time when we were on our 'Nerdy Night Out'. I wonder if that's why he likes them so much... hmm, maybe my Boss is a bit more perverted than I first thought...
