The helpless girl Shion (played by Makiko Kuno) lives freely in a church, where she learns not love from the radical priest, but endless hatred. In her childhood, Shion was chosen as a warrior of God and trained as an assassin. For many years, her world consisted only of cold-blooded killings. One night, under the priest's orders, Shion goes to Tama City to assassinate the mafia leader Ishizaki. Wherever she goes, there are no survivors, and anyone who witnesses her murders is sure to die. A third-rate magazine reporter, Sakuma, follows her with his colleague Ito (played by Johnny Ohkura) and captures the entire process of Shion committing murder. However, their actions are exposed, and ultimately Sakuma sacrifices himself to allow Ito to escape with the film. Due to the involvement of sensitive religious organizations, Ito's publishing company refuses to release these photos. Meanwhile, Shion quietly arrives at Ito's residence. This encounter changes their destinies forever...This film is adapted from the original work 'Shion' by Bangetsu Hanamura.
