Mishima who has cute face, long hair, get bullied by his classmate (include Kirino and Yumeno) because he is gay.
Eventually Mishima found out that Kirino HAS SIMILIAR issue with him :GAY, LIKE TO PUT MAKE UP
They become close. Kirino even act as his true self, use girly word. Put on make up together, chat about their self openly. At the rooftop school.
I thought they will ended up together. But its look like not.
Especially when Yumeno who also bullied Mashima help him from was almost raped by teacher.
Yumeno confess to Mashima, its look like Mashima has a bit feeling too towards him.
Smells Like Green Spirit
