Unable to cope with the pain of being raped and carrying a child as a result of her ordeal, she attempts to commit suicide and abort the baby by pounding a rock into her abdomen. Shu, however, intervenes, taking the blows of the rock on his hand which he uses to cover her abdomen.

Along with Karin, Anna is one of Ririka's best friends.  They are in the same 4th grade class together at White Dove Academy (白鳩学園) and hang out together regularly both at and away from school.  Anna is a very shy, reserved girl and always speaks very politely even to her friends.

Mami is one of Sana's friends. She is a quiet girl, with short black hair kept back by a hairband. During Akito's troublemaker days, she calls Akito a "monster", "demon", or "devil" (depends on the language), which is a particularly hurtful word for Akito to hear since it's what his sister calls him. Akito gets revenge by getting the other boys to throw Mami into a pond, which causes Sana to become angrier than she's ever been. Mami remains traumatized by this incident for quite a while afterwards. She remains so afraid of Akito that when he tries to talk to her, she screams and cries. But when she sees that Akito regrets the way he's acted in the past, they reach an understanding.  From: Wikipedia.org

Asako is a popular actress. She was also Rei's girlfriend who dumped him to concentrate on her acting career, which partly triggered his downward spiral to homeless bum.

When Sana realizes (with Akito's help) that Rei is not her "pimp" nor her boyfriend, Asako and Rei reunite. Asako continues to recur until the end of the series.
