Kamiazuma, Touka

守東桃香

Touka is the titular protagonist of the series and the child of Yumiko Kamiazuma. He possesses the sacred Stone sword within his chest. Some believe he is the reincarnation of Isabihiko, the former owner of the Stone Sword. In reality, he is a non-human replacement for Yumiko's lost daughter, who is also named Touka, and the Stone Sword is an integral part of his body.
Despite his cold attitude towards Momoka, they share a very close relationship, to the point where he considers her one of the most important people in his life. He also usually always gives in to Momoka's requests. It is later revealed that he does, in fact, have feelings for Momoka.
