Shows a hardworking side. Kind. Becomes like a tsundere. Wants to be pampered only by his lover. Will do any housework (cooking, etc.) for his partner. Starts showing his bare face (even with dark circles). His voice becomes sweeter and gentler than his professional voice. Occasionally pats heads like he does for his younger siblings. [Reason for participating] He has three younger sisters and two younger brothers; his parents passed away when he was a high school sophomore. After their death, he wanted to go to university to become a teacher, but gave up his dream to work at a host club to earn an income. He truly cherishes his siblings and never smokes in front of them. He is caring and capable of housework. Because he doesn't want them to give up on their dreams, he wants to win the game and get the money at all costs.

[Reason for participating] Actually graduated from the same high school as Shun. He met Shun during the cultural festival when Kai was a senior. He remembers Shun, then a freshman, passing by and looking at Kai's watercolor displayed in the art club, smiling like the sun and saying, "I really like this." Hearing from a high school friend that Shun was participating in this game, he joined to see him again (it's a one-sided crush, and Shun doesn't remember Kai's face). He doesn't need the money.
