Formerly a servant for his twin sister, was beheaded in order to save his sister and was reborn into the world of vocaloid
He is a patient kind loving android who loves to be doing things for the vocaloids. He is intellectual in all subjects but doesn't often use his intellect in circumstances that require little help. When things are major such as a fight, he often sacrifices himself for others.
