She's a great character. So tsundere.
One of my favorites was (legit spoiler inside for those who haven't watched)
Spoiler: Tsubaki "Sixth" Kasugano. Then I saw the scenes where it turned out she was ritualistically raped and that drove her to insanity. Still a cool character though, deserved more screen time.

Arise, romantic tendencies aside, is a cool character as well.
