Hina is a classmate of Yui and Hachiman, who is a quiet girl and hangs around Yumiko. She is a fujoshi, which is why other boys from her class are always avoiding her. During the school trip, she asks Hachiman in a roundabout way to prevent Tobe's confession. This leads to Hachiman making a fake confession to her in front of everyone including Yui, Yuki and Tobe, she rejects him and indirectly rejects Tobe as well. Although she later thanks him for taking the hit, she confesses she's "rotten to the core" just like him, and tells Hachiman that she could only be in a relationship with someone like him.
