Кёко Хаякава

Синдзи Ито's girlfriend lives in Chiba and attends the Seiran all-girls school. She appears very feminine, gentle, and naive, though she was once a delinquent and the leader of a female gang. She is constantly worried about Shinji and asks him to stop getting into fights, but in difficult situations, she always lets him go help his friends and never stays on the sidelines herself.
