Kaya is a female oni who is very, very sneaky! You need to be careful when using her against enemies because she causes them ALOT of pain. She is excellent at forming a bind with the enemy and letting them get close to her. When they do though she breaks them down little by little. She will drive them insane just to make them stable then do it again. She will spend a lot of time doing this just to give them hell and living in it. What's nice with Kaya is if you call her off she will come off just to teach someone a lesson. She should be used for someone with major enemies.
