He was part of the Twelve Guardian Ninja, an elite group that eventually fractured when six members attempted a coup. He fought back alongside Asuma Sarutobi, Kitane, Nauma, Tou'u, and Seito—though only he, Asuma, and Kazuma survived the conflict.
After the group fell apart, he took over as head monk at the Fire Temple, a prestigious monastery known for housing monks with extraordinary abilities. Even during his Guardian Ninja days, he'd attracted serious attention from underground organizations—enough that someone put a 30 million Ryo bounty on his head.
