In a modern world, he was the forgotten adopted son, the perfect student no one ever saw, the boyfriend betrayed and ridiculed to the bone.  
When he finally broke, he didn’t cry.  
He laughed.  
And together with the only girl who understood his madness, he turned the school into a circus of blood, fireworks, and red confetti.  
He died smiling, in her arms, happy for the first time.

But death was just the opening act.

Reincarnated as two little demon children in a basket, left at an orphanage in a world of magic, they discovered that every victim of the massacre had been brought along — memories intact, hatred boiling, and now equipped with powers, levels, and skills to fight back.

The treacherous ex-girlfriend.  
The 14 guys who laughed at him.  
The classmates who filmed it.  
The teachers who looked the other way.  
They’re all here.  
And they all remember.

But Joker and Harley don’t want revenge.  
They want to play.

In a world where women are treated as commodities and abandoned children are forgotten, they’re going to build the greatest circus that ever existed.  
With a family of eight insane little sisters, an eternal mother who hugs you to death, and a big sister who came back from the future — only to find out they’d already saved everyone.

Because anyone who messes with their family becomes fireworks.  
And anyone who becomes family gets eternal hugs.

Here, kings, heroines, goddesses, and even the victims themselves will learn the most important lesson:

The Joker never plays fair.  
And the show…  
has only just begun.

We walked into school hand in hand, toothpaste-commercial smiles. Spotless uniforms, backpacks heavy with death. The sun shone strong, as if the sky knew it was going to be a special day.


Professor Yamada-sensei started roll call.


Hana raised her little hand, angel voice:


I stood up, placed the theater mask on my face: half smiling, half crying.


Some students stared, thinking it was Monday cosplay.


Yamada-sensei sighed: "Take that off, Kuroe-kun…"


I turned the mask to the giant smile side.


— Not today, sensei. Today the show is special.
