Description：Tsurugi Shopping Street is an old street with a history of 100 years. The merchants here care for each other and are friendly and kind. The 20-year-old Sarumaru Yataro (played by Hayato Ichihara), nicknamed "Asaru", runs a locksmith shop on the shopping street. He has inherited his father's true teachings and has mastered superb locksmith skills. Although he is lustful and impetuous, Asaru has a high degree of professional ethics. For example, the owner must be present when unlocking the lock and he never asks or peeks at the items behind the lock. These have brought him countless reputations and trust. Asaru also has a few buddies who grew up together, the stubborn and reckless Ritsuko (played by Ashina Sei), the extremely lustful Yamamoto (played by Watanabe Gota), and the timid little policeman Yamada (played by Takaoka Soufu). They have all brought countless excitement and fun to Asaru's life... This film is based on the manga of the same name by Naoki Serizawa.
