Рин Эйюдзаки

Rin, childhood friend of Sota, has not seen him in person for a long time, but they have maintained communication through text messages. Since it had been a while since their last encounter, and Sota assumed Rin was a guy, they did not recognize each other at their first meeting. However, the misunderstanding was soon resolved. Rin loves Sota, and a yandere flag occasionally appears over her head.
