Hiruma Masatsugu

Hiruma Masatsugu was a bushi of the Crab Clan who became a Lost Maho Bujin.

Dishonored
Masatsugu had a shameful history of brawling and gambling. He returned tainted from a routine patrol south of Shiro Kuni. He was arrested for robbery and assaulting a merchant, so Masatsugu claimed to the arresting magistrate to go "looking for Hida," entering alone in the shadowlands to die fighting the demons instead to commit seppuku.

Maho Bujin
Thirteen years later Masatsugu alongside another Maho Bujin was seen slaughtering a Bayushi's legion in a mission near Seigo no Kamae river. The Crab had not redeemed himself through sacrifice, and instead had joined the ranks of the Lost.
