Ghost Bat is a ghost whose only motivation is to have fun at other’s expense. He has no regrets and any act is justified as long as he has fun.
Ghost Bat can posess any artifact at will, but he’s particularly fond of scary items and war artifacts that can be scary for humans.
His favorite things to posess are baseball bats, hence his name: Ghost Bat.
Wananeko and Dorobanii have quarrels with him all the time, as they think he’s way too noisy and draws too much attention to the other yokai. They both believe yokai should keep a low profile.
