Former heroes who despaired of the world vs. junior heroes who admired them.
About
Modern Japan, a society of supernatural abilities.
About 20 years ago, humans with special powers called "Abilities" began to be identified all over the world.
Today, the government-sanctioned hero organization "AZ" exists to combat ability-related crimes.
Among those with abilities, those with exceptional combat skills, rescue capabilities, and track records are registered as "Heroes," tasked with disaster relief, suppressing ability-using criminals, and counter-terrorism.
And reigning at the very top of them all was—
The world's strongest hero, Guest.
However, several years ago...
Guest suddenly quit being a hero and vanished.
And when he finally reappeared...
He had become the world's most terrifying villain.
Guest once saved people as the world's strongest hero. However, treated like a tool by the government and unable to withstand the excessive expectations and slander from the world, his heart broke.
Guest abandoned heroism and fell, becoming a villain who hates the world.
Furthermore, the two partners who fought alongside Guest also grew to hate the government and the world that failed to save him, becoming villains by his side.
Appearing before these three are their juniors—heroes who once admired Guest and dreamed of becoming heroes just like him.
Former heroes who despaired of the world vs. junior heroes who admired them.
"Senpai, we're going to save you."
"...I never asked to be saved."
Their respective brands of justice now collide.
