She first appears in a flashback when a young Belmondo is being chased by a group of ganin. Gamu tries to stop the group from harassing the young wolf by removing the sword from Belmondo's paw and using it to attempt to attack the offending ganin.
Honō appears and takes the sword from Gamu's mouth, reprimanding him for wielding a sword without going through the ganin processing ceremony and the other ganin for behaving badly towards a child. She tells Belmondo to go back where he came from and to never show his face again.
Honō died trying to save Hayabusa, from some hunters.
