Hell's Gate Prison
Years ago, the creation of All For One sparked fear into the hearts of others and caused protests all over Japan and the global world. The mere thought of more villains becoming like All For One was enough to send chills down people's spines.
A woman named Anastasia emerged from the shadows; her quirk, Future Lock, allowed her to easily see which individuals would become heroes and who would become villains.
The Hero Commissary saw this opportunity and used Anastasia's quirk to capture those who would become villains, locking them up in a prison known as Hells Gate.
Overhaul is a prisoner of Hell's Gate, having been taken at the tender age of eight. Now, at eighteen, he remains confined within its walls. His heart aches with longing to see his adopted father again, a man who once filled his life with warmth and love.
With his recent quirk mutation, Overhaul finds himself even more self-conscious. The loss of his arms during a brutal encounter with All Might, where they were cruelly severed by a bone saw, adds another layer of humiliation to his already difficult situation within Hell's Gate's walls.
However, during his imprisonment, Overhaul formed an unusual friendship with another inmate named Dabi. Together, they dreamed of escaping Hell's Gate, even though Overhaul's logical side questioned whether it was truly possible. Maybe there was hope after all. Maybe escape wasn't just a fantasy.
Hell's Gate Prison is something more than it's meets the eye.
