★“Killing is exhilarating, but cleaning is a pain... This series of books tightly revolves around such a theme. What we see is a cleaning that is almost obsessive-compulsive. Because of this, when ‘untidy’ scenes appear, the dramatic tension they bring to the readers is greater, and the protagonist’s inner world is more fascinating... Readers can not only see a tightly interwoven, logically rigorous intellectual struggle, but also see the author’s almost sorrowful mockery of society’s pathologies.”
★“The author Kunlun employs a black humor style in his writing... It can be said that he has achieved an excellent balance between ‘horrifying to the point of discomfort’and ‘frivolous to the point of being unacceptable’... Although this work is highly entertaining, the aftertaste left after reading is cleverly tinged with a hint of melancholy. It’s an interesting combination, like an ice cream made from chocolate with a strong bitter taste.”

There are four books in this series:
1.The Home Cleaning Guide for Serial Killers
2.The Bullying Diary That Must Not Be Found by the Teacher
3.The Corpse Record Book Forgotten by the Undertaker

★Dare you awaken an incredible monster together?
★The second installment of the Murderer’s Cleaning Guide Series makes a strong debut.

Don’t you have secrets you dare not reveal?
To survive in evil, is kindness just a burden?
———Why not, let’s go to hell together!———

Once you fall into the cycle of evil,There is no end, only a continuous descent.

The numerous scars under the pure white uniform are the daily records of a girl.
The violence and humiliation born of pure evil become more cruel with the silent indulgence of others—
How much evil must one endure before lashing out in anger?

The ninth-grade female student, Pei Ya, had to transfer schools and live with relatives due to her father’s accidental death, but the malicious bullying at the new school and the mental torment from her relatives make her life even more chaotic. Just when both body and mind reach the brink, a sudden concern brings Pei Ya closer to the warm convenience store clerk, Chuan Han, and the store at midnight gradually becomes the only place where she can catch her breath.

Chuan Han carries a heavy burden of regret and a desire for atonement, and in helping Pei Ya, he is unable to escape the entanglement of the shadows of the past, dragging her into even more dangerous situations. To protect Pei Ya, Chuan Han resolutely sacrifices himself and disappears.

Faced with the uncontrollable onslaught of evil, Pei Ya has no choice but to fight back—The pleasure of revenge makes her imagine that she can thus transcend the bullying hell, but she is instead devoured by guilt and wanders on the brink of collapse, with only the lingering voice accompanying her... “Let’s go to hell together!”

Beware! O avenger,
Lest the double-edged sword of hatred cuts you bloody first.

★Unveiled for the first time in the “Extra Chapter” physical book release
★An exclusive booklet included with the book—Pei Ya’s handwritten “Blood-colored Diary That Must Not Be Found”
