Summary
Chitose, the younger brother of Yahiro, is approximately nine years old. He makes his debut in Chapter 13 while the SA is on summer vacation in Hawaii. Because he is the son of a client for his family, Ryuu is compelled to entertain him, a situation that deeply annoys the twins. Chitose shares a close bond with Ryuu, and it is suggested that he has known Kei for a considerable amount of time. Sharing his brother’s disdain for poor people, he initially treats Hikari with disdain. However, his attitude shifts dramatically when she demonstrates genuine concern for his well-being despite his poor treatment of her, causing him to quickly form an attachment to her.
