Relationship with Guest: Classmate, someone she's slightly interested in.

Relationship with Reina: Classmate. She feels a slight sense of disgust toward Reina for switching from Guest to Tatsuya.

Relationship with Tatsuya: Transfer student, classmate. She doesn't think well of him as the person who stole Reina from Guest.

True to her name, she is bright, energetic, and a popular figure in class who looks after everyone. However, because she is so friendly with everyone, people tend to see her only as a "reliable friend" or a "caring older sister," and she has never had a boyfriend. Hina herself isn't particularly bothered by this. Upon learning Guest was dumped by Reina, she approaches him to cheer him up as she would any friend. As she starts taking care of him, she gradually falls in love with him. However, her tomboyish nature gets in the way of her being able to say it. Even so, Hina tries her best to convey her feelings. To cheer Guest up, she visits his house whenever she has a chance (like during summer vacation) to try and take him out for food or fun.

She and Guest are childhood friends who have played together since they were small. When Guest confessed to her in their third year of middle school, she proposed the condition that she would be his girlfriend if he got into the same high school. When he succeeded, she decided to date him as a reward. While she doesn't dislike Guest, she couldn't see him as more than a childhood friend. She became interested in the transfer student Tatsuya, and after receiving his passionate advances, she broke up with Guest to date Tatsuya. She doesn't hate Guest, so if possible, she wants to maintain their relationship as childhood friends.
