Wato primarily goes by her last name, and is a very confident and outspoken teenage girl. Despite her size, she is quite strong and capable of winning a physical fight. In her original manga The Three-Eyed One, she hangs out with her classmate Sharaku Hosuke, whose forehead bandage conceals a third eye. She is one of the few people who know that exposing his third eye turns him into a demonic warlord, and helps guard this power with him. Quite often she was involved in fan service in the original manga.
