Akaza is a headstrong, stubborn and battle-crazed Social Darwinist who enjoys fighting, especially against strong Demon Slayers. Akaza looked down on anybody he deemed weak, so much so that his skin would crawl at the sight of them. He genuinely respected those who were strong in his eyes, demanding to know their names, and would not stop until he finds out; he remembers all the names of strong past opponents and committed them to memory as tribute to their strength.
