Shion is a young girl with brown eyes and short curly hair (she is affectionately called pube head by the others due to her hair, something which she dislikes). She has a tan skin color, unlike most other characters and is often seen wearing her school uniform, but also her freetime clothes.
She talks to Hiro, and confesses after she witness him save Ando. Eventually after Hiro flees from the police, she picks him up, and lets him live with her and her grandma, while refusing to believe he is a murderer.
She eventually finds out he is the murderer, but somehow manages to convince him to become a good person. This last for a while, before the swat team shoots her and her grandma, leaving them gravely wounded. Though they reappear just fine, with them noticing that Hiro leaves money in their bank account.
