The author continuously plants suspense throughout the story... Each narrative thread intertwines with the others, and in the end, the author skillfully weaves them into a complete and logical picture, revealing the truth. —Writer | Chan Ho-Kei

Killing is thrilling, but cleaning up is agony... This book tightly revolves around such a theme, presenting an almost obsessive level of cleanliness. Because of this, when “untidy” scenes appear, the dramatic tension delivered to readers is even greater, and the chaos within the protagonist's inner world becomes all the more fascinating... Readers will not only encounter tightly-woven, logically rigorous battles of wits but also witness the author's almost sorrowful mockery of societal sickness. —Writer | Chang Hui-Tzu (Little Flower Mom)

Kun Lun employs a black humor style to handle the narrative... It can be said that a remarkable balance is struck between “being thrilling to the point of discomfort” and “being flippant to the point of unacceptability”... While this work is highly entertaining, the aftertaste it leaves is cleverly tinged with a hint of gloom. This is a fascinating combination, like ice cream made from intensely bitter chocolate. —Mystery Critic | Luna

An obsessive, cat-like teenage killer; an unlucky but optimistic office worker; a broken, vengeful girl; a corpse trader who has forgotten his name; an enigmatic and stunning psychologist; a sunny-smiling dessert shop owner; a mysterious, bloodthirsty organization of serial killers; and an elusive information broker—
Do you dare follow them into the dark abyss of your own heart?

This series consists of 3 volumes: A Home Cleaning Guide for Serial Killers, A Bullying Diary That Must Not Be Discovered by the Teacher, and The Corpse Trader’s Forgotten Record Book.

Don’t be too surprised to see the hunter become the hunted—
it’s merely an everyday scene in this dog-eat-dog world.

The counterattack is in full swing!
The hunters who seem to hold the upper hand—
will they be overrun by their prey?

▍Hell has its own cycles;
it turns out nightmares really do repeat themselves.▍

Among the corpse traders who obey the orders of “The Factory” and specialize in body disposal, a fierce new operative emerges. With no memory, he asks no questions about the past, seeks no future, and has no name—only the codename “Lion.” Lion repeatedly receives disposal requests from a certain girl who insists on meeting him, and she seems to recognize who he once was…

Has the killer Ten Years gone from hunter to prey!? This time, the Jack organization launches a hunting plot against him, striking back violently. Everyone around Ten Years—friend and foe alike—even the corpse trader Lion, is dragged into this chaotic hunt. Threats run rampant, closing in step by step. Who, if anyone, will make it out unscathed?

When the bloody farce temporarily subsides, Lion returns to The Factory to face an execution order, while Ten Years seeks out the mastermind behind it all. Both step into the ambiguous border between good and evil. Can they each reach a final resolution…

▲Friendly reminder! Mind your step—
you, standing on the edge of a nightmare, might bring it to life with one more move...▲
