★“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
