The story follows Masashi Tachikawa, a clerical worker employed by Death Brand, an evil paramilitary organization which aims to conquer the world. Although content to stay out of trouble and keep his head in the paperwork, everything changes when Masashi loses consciousness during a meeting with his superior, Ragulia, and awakens to find that he has been transformed into an inhuman monster with tentacles for hands. To Masashi's horror, Ragulia explains that, due to budget cuts and the expense of replenishing their combat force with outside soldiers, Death Brand have begun turning some of their non-combatant workers into combatants. If Masashi wants to become human again, he must defeat two magical girls, Mana Blue and Mana Red, in such a way that they will never interfere with Death Brand again...
