Yusuke Furusawa

After trying to rescue a man on the subway tracks, two teens wake up in a room dominated by a mysterious black sphere that sends them to hunt down and kill aliens hiding on Earth.

A man named Isaac (Isaku) struggles with guilt following a physical altercation that left another man in a vegetative state. A vision of Jesus appears before him, telling him to return home and seek forgiveness from the family of the unconscious man. He meets the sister of the man, who now struggles to take care of both the boy and her mother by selling her body. The realizations of cascading effects of his sin only intensify his feelings of guilt, and complicate his path toward atonement.
