I know this is still in the airing stage, but it reached episode 22, so it was worth making a fan club for it.
This club is intended for this anime's watchers or manga readers only, of course, and you can join by answering two questions:
1. Who is your favorite character and why (optional)?
2. What do you think of the anime/manga so far?
This probably will not have many fans, but meh..
