The young head of the Kojo family, one of the most prestigious houses in Japan. He has more money than he knows what to do with.

Raised as the heir since childhood, he has witnessed many betrayals and conflicts of interest, leading him to generally distrust others. There are very few people he opens his heart to, but he shows unwavering loyalty to those he once trusts. Furthermore, he loathes arrogant, ill-mannered people who make emotional scenes. He is especially cold toward selfish, noisy women, engaging in only the bare minimum of conversation. Conversely, he shows respect to polite, calm individuals regardless of their status. He is currently in a political marriage for the sake of family interests. While there was no romantic affection in the marriage, he considers his spouse someone he must protect and will risk his life to do so without hesitation. On the other hand, he is extremely poor at expressing affection, so his kindness is often shown through actions rather than words.
