1. Kafuka: Scariest character I've ever seen. Manipulative, but keeps an absolutely cheery and happy facade that you'd barely suspect her, even more than Mayo.
2. Chiri: Her perfectionist attitude can lead her to do extremely scary things, especially with that shovel. If she weren't so proper and predictable, she'd probably be on the same level as Kafuka.
3. Chie-sensei: She gives creepy stares sometimes, and as someone who took Psychology classes, she creeps me out as a councilor.
