Killer B is a cheerful, eccentric, and incredibly self-confident ninja who is used to expressing everything through rap, even if those around him do not always understand his rhymes. He wears sunglasses, always speaks in a singsong voice, and seems frivolous, but behind this mask hides a sharp mind and deep wisdom. B went through the same prejudices as other jinchūriki, but chose a different path — instead of bitterness, he answered with a smile and decided to become the best host, so as not to let his brother the Raikage down politically. He holds no grudge even against those who tried to kill him, and is capable of forgiving sincerely and without unnecessary words. B possesses an amazing ability to feel another's heart through touch, most often through a fist strike. He is fearless but not reckless, and his loyalty to his brother and village does not prevent him from making independent decisions when the situation demands it.
