Sincerely, my favorite characters are Hong Meirin, Yuyuko, Prismriver Sisters (Poltergeist Trio) and Reisen.
Man, I love fighting those guys, especially because of their music.
I don't really get it why people MUST come here just to make fun of what people like. Yeah, we like Touhou, got a problem? It is a really hard game even in easy mode, great sounds, funny/great/interesting characters.
People make fun of japanese culture (Anime/Manga/Etc) without even knowing anything outside of the stereotype.
