He is a calm man, he is mostly serious. He mostly will act as if he was a scientist commenting on things in a scientific way. He is very observant, often commenting on an action or emotion that his opponent his doing. Like Takashi he is very loyal to Sentonara, doing anything that he is ordered without question.

He has a great love to experiment with different forms of kido and spells. Including healing and many other dark spells, he even studies the immortality spell that Sentonara uses.


Original from the 12th division of the Gotei 13 as a seated officer, he was exiled because of his personality and ethics. He had a great lust for becoming immortal, so he developed a spell that would allow him to drain the life out of people and add it to his.

He was founded out and exiled from the soul society, wanting revenge for his exile he plotted to get back. Then he met Sentonara, making a deal with him to serve him. He will be able to get his revenge on the soul society. He then became a Kozuki Agent and now is believed to be working somewhere in either the world of the living or Hell.
