Tower of Overturn

In a world dominated by seven super-corporations, the Longevity Species that always occupied the pinnacle of power didn't allow for the enactment of written laws. The Floating Islands of prisons delimited by lines on the map, where resources would inevitably run out in the future...
People yearned for the birth of a true "Hero," yet they cynically awaited the fall of a Hero from grace.
As long as one was hailed by the media as a Hero, even murder could be forgiven, and every word they said would be adored. Even high and mighty Elves dared not provoke the edge of a Hero.
But if a Hero of the past committed even a minor offense, the moment their image crumbled, the forgiven sins would flare up like an inextinguishable furnace, and the stars of yesterday would instantly become unforgivable criminals...
"—Come become a Hero, Russell."
The most vicious criminal in the world thrust a knife into the boy's hand, whispering a low enticement.
