Eden No Hana

Midori and Tokio have lived separately since their parents died in a fire 13 years ago. Midori hates her school and foster home and drops out of school and leaves home. On her way to Tokyo Tower, she meets a man who happens to be her brother Tokio. Midori has no idea that this man is her real brother. She ends up back at her foster home, where she is habitually raped by her stepbrother. One day, Tokio rescues Midori when she is cornered by her stepbrother. "I am your real brother and I have come to take you back." Hearing Tokio's words, Midori jumps from the second floor into the arms of her long-lost brother. Reunited, the two estranged siblings go in search of Eden, a paradise where nobody has ever been to.
