(the anime or the manga, though i only know the adaptation of the anime because i only own the first two volumes of the manga. also please no spoilers for traumend/season 2, i'm still watching it ^_^;)
what the title says. it's my favorite anime ever and so far the only one i've managed to watch all the way through. it's cute, it's funny, it's interesting, it's absolutely gorgeous visually, and just a little bit sad.
you might recognize this character if you were on the internet in the early 2000s, desu~
