Rei: looks like Satan in human form when she gets mad. Like, Jesus Christ the sports festival... Osoro thought they would die just fighting her.
August: not very scary but he carries around a riding crop.
Hino: horrifying because he's usually calm and sensitive. His breaking point is when someone hurts Rei's feelings, hurt Eve, or mess with Haruhi.
Haruhi: not that scary, usually to stupid to care
Eve: give her cookie or kneel to her feet.

Kirimina

Akane: tries to be scary but can't be

Iro: scary af, back up.

Miruhawks

Dove is scary when she's mad but not on Rei's level. She carries around a dagger in case she needs to use it, but she usually doesn't carry it.
