Vast in a city full of monstrous beasts and powerful villains, True North, the world's top hero, along with other heroes, use their inherited or gained abilities to fight for justice and defeat evil.
Haruki Amakusa, a mere student with no Variant whatsoever, gets home tired and exhausted due to the fact that he is now on a long-term vacation after middle school. He then sets his mind on one goal: he wants to be a hero. His father always discourages him, because Haruki has no Variant and his father wants him to have a peaceful life without facing the consequences of being a hero. Stubborn Haruki denies this fate and spends his time working out. After that, his friends, knowing he worked out, show him that even though he has trained, he must have a unique Variant to be a hero.
Sad, Haruki goes to his room and cries. Two weeks later, Haruki changes from an energetic young man to a cold, antisocial dude scrolling through his phone to look for the latest shoes.
Suddenly, an unknown account asks him a question:
"Do you want to be a hero?"
Startled, Haruki sees this as an opportunity to be a hero but assumes it's just a fluke.
Then another message pops up:
"It's not a fluke."
Haruki, now taken aback, wonders what to do. He then types:
"How?"
The unknown account gives him a link to open.
Is this a trap for malicious software? Haruki thinks in his mind.
"No, it's not," types the unknown user.
Realizing this might be his chance to be a hero and to shame all his friends, Haruki clicks on the link and disappears without a trace.
He is teleported to a new place within Kyoto, where a man is about to fall from a cliff.
Scared out of his wits and not knowing the change in his appearance but knowing he is now a hero he flies to save the man.
After that incident, instead of applause, the crowd stands in silence, watching Haruki strangely.
Suddenly, True North appears, seeing Haruki with the man.
"Look! True North! I…"
"Begone, you evildoer."
Haruki, after hearing those words, becomes silent, questioning why the great hero True North would say such a thing.
Suddenly, Haruki receives a punch from True North, sending him crashing into a building.
He suddenly sees his face reflected in a broken mirror as a villain and questions the system.
[Haruki stares at his villainous reflection, voice filled with disbelief.]
Why do I look like a villain? I was supposed to be a hero.
I worked hard. I believed.
Is this what the unknown user working for the system thinks how I would display justice should work?
What am I supposed to do now?
True North now enters the broken building where Haruki lies.
What troubling fate awaits Haruki? Or is this the system's cruelest joke of all?
