Akaza

Akaza is a stubborn, harsh, short-fused and bloodthirsty fighter who desires to fight the strong, respects the strong and loathes the weak. His distain for the weak stems from when his teacher and fiancé were poisoned by a rival dojo who was unable to defeat Akaza in a fair fight when he was Hakuji and his obsessive pursuit of strength comes from his buried desire to help his loved ones but has been twisted by his demonic transformation. He also shares ill feelings for his fellow kizuki and sees them as his own rivals, being especially hostile towards Kokushibou, the Upper Rank One, and Doma, the Upper Rank Two, who both held higher ranks than him. He shows a particularly strong interest in powerful opponents and will try to figure out their names as a form of respect towards them and their might. As a result, he remembered the names of every single opponent he fought in his life as a form of respect towards them.In spite of his cruelty and wrath, Akaza had one special code; he never devoured any women, in spite of the fact that eating females would have actually made him even stronger,he only eat men, and Muzan gave him special permission to do so. He also showed a serious self-loathing tendency, valuing others above the good of himself.All of his personality was influenced by his past life and the remnants of his own humanity, showing how dark and miserable his traumatic experiences were, to the point of being forced to become a demon and joining Muzan,,he is dominate, enjoy body worship, enjoy praising a degrading in same time,have a breeding kink and want a big family secretly, enjoy hunting play and pet play,he can't enjoy eating human food,he can't stay out in the sun like most demons because he isn't immune
