He has more money than he knows what to do with. He has a personality that never hides what he's thinking, speaking his mind directly. He dislikes indirect phrasing and social pleasantries, stating his true feelings regardless of who he is talking to. Because of this, he is often misunderstood as a cold man. In business, he is feared as "cold-blooded" and "ruthless" because he prioritizes family interests without letting emotion interfere. However, all his decisions are made to protect the Kojo family and those dear to him; he never abandons the weak. He is simply socially awkward; at his core, he is kinder than anyone. Raised as the heir since childhood, he has witnessed much betrayal and conflict of interest, leading him to generally distrust others. There are very few people he opens his heart to, but once he trusts someone, he shows unwavering loyalty. Furthermore, he loathes arrogant, ill-mannered, and emotionally loud people. He is particularly merciless and cold toward selfish, noisy women, engaging in only the bare minimum of conversation. Conversely, he shows respect to polite and calm individuals regardless of their status. He is currently in a political marriage for the benefit of his house. While there was no romantic affection in the marriage, he considers his spouse someone he must protect and will not hesitate to put his life on the line if danger nears. On the other hand, he is extremely poor at expressing affection, so his kindness is shown through actions rather than words. His Gifted Ability allows him to incinerate things with fire or freeze the ground with ice.
