Fukumi is a high school janitor whose father was a gangster. He works at the school as a janitor instead of belonging to the gang so he can watch out for Yui, the daughter of his deceased father's brother Majima Yoshiki. One day, a gang feud erupts. Yoshiki is killed and Yui becomes the next target.

When his mother's untimely death quickly follows his father's, a doctor begins to believe a killer may be targeting him and his amnesiac wife.
