Kagehisa Anotsu

He is the leader of the Ittoryu and an equal of Manji. This emotionally cold young man has prodigious skill with the sword and leads the Ittoryu. He runs Ittoryu in order to form a dojo dedicated not to form and rules but to the simple test of superior lethality. He was brought up by his abusive grandfather a swordsman disgraced by the Asano dojo the dojo of Rins family. Anotsu is as pragmatic and shrewd as he is deadly although he isnt as inhuman as originally believed. He even allows Rin to live after she attacks him. He has two weapons. The first his main weapon is a Nepalesebased axe named Kabutsuchi Head Hammer. The other is his rarely used sword of the same name. Source: Wikipedia
