The Raijū (雷獣,"thunder animal" or "thunder beast") is the personal summoning of Hiroshi Kyoko. It takes the form of a huge beast (the mix of a cat, weasel and monkey) completely composed of fire. Since it's body is made up of fire, the Raijū burns any and all that come into contact with it. In addition, it can generate and create intense heat and aid it's summoner in using Fire Release techniques.
