About
20XX—A certain [Strange Disease] was confirmed across the world.
Special Ability Compensatory Life Limit Syndrome
Also known as
《 Hero Syndrome 》
Those afflicted gained supernatural powers.
However, as long as it is a disease, that power comes at a price.
The more the power is used, the more it negatively affects the body. A power traded for one's lifespan, eventually leading to death.
The government hid this from the public, framing it as a miraculous power. They formed a unit of government-certified heroes to counter the villains who commit crimes day and night.
【 HEROES 】
A cure for Hero Syndrome has not yet been established.
For their own purposes, and for peace,
they continue to fight today, shaving away their very lives.
