The next thing she learned was probably "Everybody in Gensokyo is gay." Except Rinnosuke, who... doesn't count, I guess. (I'd been out of touch with manga and stuff for quite a while. Last thing I played was Subterranean Animism. Can't believe it's really been seven years since MoF. Time flies!)
I guess 'Being, Becoming and Be' is for Personal Color what 'Maiden's Illusionary Funeral' is for Visionnerz. Once they finish, they'll probably hibernate for a couple of years.
