Fuse

is a human male in SaGa Frontier. He is a patrolman for IRPO. As befitting his name, he has a short temper and gets cross with anyone who makes him angry. Fuse personifies the "bad cop" in the classic "good cop, bad cop" duo, with his former partner Ren being the "good cop". From what little is known, Fuse greatly respected Ren as an officer and acknowledged his partner's abilities. He excels in hand to hand combat and is generally geared towards learning all the Martial Arts moves in the game.
