Remix: Sensitive Heart (Fallusion, Scarlet Destiny...). Definitely calming music.
Doujinshi: can't decide... they're too many cool Doujinshi's out there, so I'll just mention some:
Sakuya Izayoi, Run, Kill!, Lovers High!!, Two By This Side, Three By The Other Side, Advent Cirno, Clash House, SapuriI haven't read enough doujinshi, I feel =_=
Doujingame: Mystical Chain for now.
Etc: Walfas' Touhou stuff, Happy Flame Time's Sukima Switch (and comics & stories)
... Turns out I just listed my favorites.
