Hinako has the classical drunk violent father, dead/married sister and abused mother. Apart from that, her friends are kinda weird. One of them just fucking dies at the beginning of the story. The other one (Shu) appears and disappears constantly and is kinda of a loser sometimes. Rinko is a huge bitch. Seriously, fuck that girl. She pushed Hinako down the stairs because she is jealous. What a bitch.
