Occult Club

Occult Club was created by Reita (which he created in an attempt to pick up chicks) but the only other people who joined were Kusuo (forced to join) Shun, Chiyo (who was just following Kaidou), and a spooky girl named Arisu. Since it didn’t work, Reita kind of gave up on it, and it turns out at some point he changed it and Kusuo turned to be the club president. Saiki later finds out she and Arisu have been the only one’s showing up for club since then.
