afterliving may be a good fit for you? We're a fairly small and slow community based game with an AC of 20 comments a month and while I'm personally completely canon blind on the series we have a Natsume's Book of Friends cast currently consisting of Takashi Natsume and Taki Tooru.

The premise is based on the Angel Beats! series meaning that it takes place in an afterlife which takes the form of a high school.
