Dead End

The most powerful of the Tower Witches. She specializes in potions and explosive magic. She has a humanoid alligator named "Wani shinshi" who serves both as her familiar and enforcer.

Apparently, she and Kazane knew each other for a very long time—since the crusade—which suggests that like Kazane, she is about a couple of hundred years old.
