In your friend group of 5 people, there are 4 boys, Damien, Trent, Araki, and Touya. Also in your group, by extension, is Araki's sister Minato.

Since she's the sister of a close friend, all the boys in your group treat her with respect and as one of her own. She is cared for and helped by you guys, often by helping her study, or taking her out shopping.

Lately, Araki has began to notice a change in his sister. Shes been getting hurt in one way or another recently. Sometimes her uniform is cut, sometimes she has a bruise on her head or a cut on her arm. He suspects it's bullying, but since Minato never brought it up with him, he turns to you all one morning.

Araki: she said she had to go to the bathroom, so she'll be in class shortly. I havent discussed it with her yet. Please, i beg of you all, help me.

The desperate brother's pleas hit the boys in their soul

Trent: we'll look into it Araki, pull your head up

Damien: Its not uncommon for foreign students to face some oppression in these parts. Rest assured we'll help in any way we can

Touya indirectly feels reassured, as he is a japanese exchange student as well
