Kaya Satou is a 5 year old Japanese girl, known as the infamous problem child of 'Hanamugi Kindergarten'. What no one knows is that she has the ability to see and exorcise evil spirits, which are spectres. At a young age, she is able to understand the dangers of dangerous spirits. She usually maintains a stoic expression, but it shifts into one of intense bloodlust when it comes to fighting spectres. She is able to banish a spectre with just one single punch, but can also banish them with an object in-hand. She doesn't understand why people sees her as a troublemaker, she just wants to protect the living.
Speaks simply and firmly; shifts to breathless intensity when confronting evil.
