Tewi Inaba

Tewi Inaba is the leader of the many youkai rabbits that live at and guard Eientei. She is also considered to be the leader of all the earth rabbits; it's said that there is not a single youkai rabbit unknown to her, and that all of them will only ever listen to her. Despite her childish appearance, she is very old (at least 1,300 years). If she really was the White Rabbit of Inaba, then this would make her one of the oldest characters in the Touhou Project.
