Summary
In Japan, many evil organisations terrorize the people and the police are unable to retaliate. One of these organisations, named Gamshack, is composed of supernatural beings called 'Kaijins'. A member of Gamshack - Shiropaya - decides to resign from the job; Shiropaya does not want to be a villain any longer, but would rather be a hero.

Shiropaya searches for a job among the heroes squadrons, but has very little success. That is when a Kaijin attacks. The Kaijin is defeated by a man named 'Red', who shows signs of great stress. It is here when an elderly lady explains that the young man - Red Koutarou - suffers from a very rare illness, but is also a very good hero, although he is alone in his squadron. Shiropaya decides to join his squadron to help him fight crime.
