- Background: Ken Masurao grew up in a military faimly and enlisted when he was old enough, wanting to apply his anger to something useful. If you ask him why he's angry all the time, you'll just get a punch in the face. Deep down, he's a likable guy but he puts his duty above anything else. He was the one who drove Itachi away when he attacked the ceremony that claimed the lives of many. He has since developed a rivalry with him. He sees the Shima siblings as unneeded help at first, but grows to accept them. When the Yoma reawaken, Ken sees a new enemy to throw his anger at along with his Auge.
