Mamiya plays the role of the family's second son Takanori who was roped in to commit the robberies by his gangster father Tetsuji (Musaka Naomasa), hysterical mother Naomi (Irie Kanako) and elder brother Satoshi (Maiguma Katsuya) as the family was in financial trouble due to debts and the mandatory contributions to the gang. Takanori's girlfriend Kaori will be played by Shimizu Hazuki. However, things got out of hand and led to the multiple murders in order to achieve their aim. Other co-stars include Ochiai Motoki, Fujiwara Kisetsu and Torii Miyuki.
