Riana Tachibana

The daughter of a guesthouse on a remote island, [Konomi](https://anilist.co/character/300940)'s younger sister. Even though she has a body that is sexually harassing due to her environment, she has become a feminist girl on an online message board. She dislikes the customs of the island and wants to go to Honshu as soon as possible. (Her boyfriend is on Honshu.) But in the end, she is more sullen than Konomi.
