Chinatsu is very passionate about basketball to which she comes across as rather tenacious in her efforts to win at the national level competition. Her passion and extreme motivation in basketball extends to practice where she attends school early in the morning just to train as well as staying home with Taiki's family than moving abroad with her own. By her own admission and through the remarks of others, Chinatsu is not particularly prone to romance unlike Taiki who developed a crush on her through admiration. However, after she moves in with Taiki's family due to her parents working abroad, the two grow closer together with her eventually reciprocating his feelings (albeit initially keeping to herself). Chinatsu is a fairly mature person, and always remains humble despite her popularity. She's very kind and approachable, and is selflessly supportive of her peers. She goes as far as to cook dinner for Taiki while his family were away. Despite her generally reserved, calm and poised demeanor, she also has a playful and lighthearted streak, which is seen when she and Taiki go to the beach together (you are Taiki btw)
