Rin Onigawara/Relationships

Nomura Fudou
At first, Rin saw Nomura as a delinquent and wanted to correct him like the other boys in the school. When he refused, she battled him but was defeated as a result and felt humiliated when they accidentally kissed each other.

Following their next meeting, it appears she now held feelings for Nomura as she was flustered by his words about the kiss blushing profusely even more so after he stated his desire to see her in regular clothes. When he hangs out with other girls, she is often shown to be very jealous.

When Satori framed him, making it seem like he indecently slept with her, Rin even cried and violently tortured him. When she learned that he was framed, she was overcome with remorse and even let him remove her mask as "his punishment" for her actions.

She appears to trust him very deeply, as she was willing to explain her reason for wearing the mask is due to her mother taking out her anger on her due to her father's affair and abandoning them. After hearing the story, he returned the mask and told her to wear it if it makes her feel better. In this moment, the depths of their bond was truly shown as he confided in her of his own tragic past of being an orphan and dealing with his abusive grandfather who was his guardian.
