After Wen Jiu dies in a car accident while saving someone, she enters an infinite-flow world. If she earns enough points, she can come back to life.
When she draws a card to choose the type of instance she will enter, Wen Jiu happens to draw the type considered the most terrifying in the infinite-flow world, and the one with the lowest survival rate: Vengeful Children.
Unreasonable, illogical, and consumed by resentment, the Vengeful Children kill every player who enters their world.
Under the sympathetic gazes of the others, Wen Jiu looks at the card in her hand and smiles with relief.
As a male kindergarten teacher, he is best at calming children down. This is right up his alley.
A child abandoned by his parents dies alone at home. He wants a family, so the players must act as his mom and dad. He hates his parents, so anyone playing them has to die too.
A child sacrificed by the villagers can't understand why he has to die. He never did anything bad, so why was everyone so happy after he died? How could they go on living with such easy consciences? Why not die with him?
She had the happiest family, loving parents, and the best classmates and friends. Then one day, a stranger she had never met killed her. Watching her parents consumed by grief, she swore to find her killer and take revenge.
All the players look so much like her killer. They're all her enemies!
He was disabled, so everyone hated him. His parents thought he was a burden and paid even less attention to him after his little brother was born. His classmates and teachers hated him too, thinking he was different from everyone else. So he would make everyone who hated him disappear.
He was a very clever child who could do anything well, but it still wasn't enough. Everyone expected him to be the best at everything. He worked hard to live up to their expectations. He kept pushing himself to the limit. But one day, he discovered that his parents, teachers, and classmates had all turned into monsters. Everyone had become a monster, and the monsters wanted to kill him.
...The monsters killed him. He had to kill the monsters and save everyone, make them all go back to normal.
He was sealed inside a jar. It was dark and cold in there. Could someone come keep him company, stay in the jar with him? He could sing for you.
Players in the world of the Vengeful Children are scared out of their wits. These kids are terrifying, even more frightening than the horror movies they've seen.
The player death rate keeps climbing, and the survival rate in the Vengeful Children world is horrifyingly low. Almost every player lucky enough to survive chooses to tackle another type of instance instead.
The number of players who have successfully cleared a Vengeful Children instance has always been zero. This series of instances is known as impossible to clear.
One day, every player receives a System announcement: a player named Wen Jiu has actually cleared every Vengeful Children instance, with a 100 percent clear rate in each one.
The players are curious about who Wen Jiu is, and how she managed to clear a series of instances that should be impossible to complete.
Before Wen Jiu can leave the infinite-flow world for good, a whole crowd of intensely curious players comes to see and admire her.
But... why are those terrifying little brats here too? They escaped from the instance worlds!!!
