Senkuu Ishigami 石神千空
Height 171.4cm (5'7") Senkuu is a genius with a vast amount of scientific knowledge. He is able to invent various kinds of tools and gadgets in a short amount of time with ease. As a child, he designed and built a functioning miniature rocket ship. Senkuu also possesses an analytical mind, being able to correctly discern the situation he is in. Even in his pre-teens, he was intelligent and sharp-minded enough to create advanced machines. Senkuu's physical abilities are very low and he would lose against someone like Kohaku in a brawl, something he himself admits.
