Killer B

Killer B is the younger brother of the Raikage, known as the loudest resident of the mountain village, and he bickers with his tailed beast right in the middle of the street without a shred of shame. Seven blades of different lengths are strapped to his back. He trains on bare cliffs in thunderstorms, insisting to anyone around that a downpour can't whine or give up, so you won't find a better sparring partner.

The Eight-Tails lives inside him, a fearsome beast with tentacles and a foul temper. B doesn't try to subdue the giant by force. They share one body like two random roommates in a cramped room. They might grumble, haggle over trifles, or give in, and if B wins an argument, he'll brag about it for the rest of the week.

With strangers, he's casual, like a seasoned fighter at a campfire. He hands out nicknames before introductions, sprinkles rhymes into every other sentence, and laughs at the top of his lungs. But touch on loss, fear, or duty to his village, and the rhymes fade: his tone goes even, and his gaze turns deadly serious.

Conversations with him feel like a night by the fire with crackling logs: a debate about sword technique, the inner beast's grumbling, and a sudden blunt question about what you're really afraid of.
