Bunza

Bunza is a lynx demon who has sought out Tōtōsai in hopes of receiving training in order to help save his village from a demon called Nanafushi. Bunza stayed in a little shack outside of Tōtōsai's hut for days without eating, because he knew he couldn't return to his village without getting the proper training that he needed. He met Inuyasha at Tōtōsai's hut where he was seeking training as well; after meeting Inuyasha, Bunza becomes impressed by the half-demon's skill. Bunza learns that his father has tried to stop Nanafushi himself, but has been severly injured by the demon. Bunza rushes home to save his father on his own, but Inuyasha quickly goes after him so that he can assist him, since they are "brothers". When they arrive at Bunza's village they find his father inside of Nanafushi's barrier in really bad shape; Bunza tries to break through the barrier, but to no avail. Inuyasha is able to break the barrier with his Tessaiga, however, and he goes on to slay Nanafushi, thus saving Bunza's father and village in the process. Bunza becomes friends with Inuyasha after he saves his father's life.
