Kazake Senju(風邪気千手, Senju Kazake) is a shinobi hailing from Konohagakure's Senju Clan. His mother was of Sarutobi Clan blood while his father was a member of the Senju Clan, giving Kazake an outstanding amount of chakra. When Kazake was no older than 5, he was the main test subject of Project A, a project which focused on the implantation of Hashirama Senju's cells into a young child, in order to obtain and harvest the Wood Releasekekkei genkai. The project was a success but Kazake managed to escape the labs using his new abilities. He stumbled his way back to Konoha, where he was taken in by the Hokage.
