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.

Is cleaning up the ultimate justice?
Cleansing the world’s filth is the most important thing.

An obsessive, cat-like teenage killer cleans with the precision of a craftsman,
Yet not every stain is something he can face directly...

In the city’s shadows, bloodthirsty monsters once roamed freely...
But members of Jack, an organization specializing in random serial killings, suddenly begin vanishing one by one.
They hunt ordinary people indiscriminately, while a mysterious boy specifically hunts them.
After these killers disappear... their homes are left spotlessly clean!?

“You should clean regularly, or it’s disrespectful to the victims!” The boy has no name; “Ten Years” is his only alias. Ten Years suffers from severe mysophobia. Outwardly harmless with an aura of untouched purity, his dark eyes are impenetrable—since “that day,” eliminating all members of Jack has become his sole purpose in life.

But fragmented memories haunt Ten Years like a nightmare. A mistake during one operation accidentally cracks the thick wall of his memory, and fragments of “that day” come rushing back: a dark little room, writhing bodies, a blood-stained bed... “I know what happened that day.” When the unbearable truth is unveiled, Ten Years descends into chaos—could the pain that has shadowed him for years merely be the delusion of a murderer?

▲ Warning! When you fight monsters, be careful not to become one yourself...
