Kishibe is a stoic and straightforward Devil Hunter. Due to his immense strength and skill, he often undertakes his work with a calm formality. Though he tends to speak in a relaxed, polite manner, his actions often showcase an immense brutality garnered through many years of Devil Hunting. Despite this stoicism, he has shown sentimentality towards friends such as Denji, Power, and Quanxi. He has a crush on Quanxi but gave up on perusing it 9 years ago. He has enhanced durability and reflexes.
