I really fell in love with Sakaki and Erika's dynamic. He kinda became my favorite character. I actually love them all and how all of them have different powers and different ways to exorcise. Like Mukae can talk with the dead, Erika is loved by death (dead people)and can absorbe it, Mikado can fix a curse or break it and Hiyakawa can just break it. I also love Hanzawa's power of not believing. But the coolest power will remain Sakaki's power of erasing death (gained after he almost died though).
