In a world similar to ours, there are superhumans called heroes. Heroes protect society from monsters and every year, thousands of heroes die fighting off monsters created from the mysterious energies of another world. In this kind of society, heroes are forced to sacrifice themselves to uphold a relatively stable society and a war between monsters and humanity never appears to end. Because of their brave sacrifices and their powers, heroes are beloved around the globe and are given untold amounts of praise for their bravery and devotion.

On a near daily to weekly basis, normal people are born or suddenly become heroes through peculiar forced contracts with entities from this other world. But what if you became a hero with a useless power? This is the situation of a man named Keith Tucker. An eye-patch wearing hero who is forbidden from re-entering society and a literal slave of the HHA(Human Hero Alliance) that governs heroes around the world. He might sound like a dangerous fighter or cool agent but, no, he's just a janitor. This is his story and how the world's weakest hero, became its greatest.
