“I can’t stand being curious about what’s going on in this writer’s head!”
Kim Young-min, Freaky, and the authors' strong recommendation ★ Tomoyuki Shirai's first novel collection!

Tomoyuki Shirai, who has been expanding the frontier of 'full-fledged mystery' with frightening momentum, finally meets Korean readers with his first novel collection, "I am a Monster, You are a Monster."
From an elementary school detective chasing a classmate's attack (The First Case), to a criminal who carries the fate of humanity on the brink of extinction (The Demon with the Big Hand), to a serial poisoning case sweeping a brothel (The Man Who Died Inside Nanako), to the mystery of a fossil from tens of thousands of years ago (Motilian's Wrist), to a locked-room incident that seems to prove a long-ago prophecy (Angels and Monsters), five stories with diverse backgrounds and genres await readers.
Prophecy, locked rooms, poisoning, science fiction, multiple mysteries… all the devices explode like firecrackers, but the narrative is solid and the puzzles are more sophisticated.
The author's writing style, which pushes the genre to its limits and keeps you glued to the point where discomfort and pleasure intersect, makes you exclaim, "As expected of Tomoyuki Shirai!"

Sohyun is Seongje's younger sister.
A twin who appeared in this world only four minutes later, he is clearly superior to his older brother Seongje in terms of intelligence.
I haven't heard from you in a while because you've been busy, but it seems like you've been appointed as a policy advisor to the Korean Ministry of Education, and you've been visiting New York with a ruling party member for the past five days.
She said that today and tomorrow were her days off, but she came all the way to Iowa to see the shameful sight of her brother, who was brought to trial for witchcraft.
“So… what actually happened?”
Sohyun rested her chin on the bar table and chewed on cashews.
"what?"
“So, how did genius chimpanzee Lily open the radiation lock?”
I guessed it.
The Holy Spirit does not believe in miraculous coincidences.
It seems that he may have been able to fool the congressman, but he couldn't fool his younger brother.

“There is one more person among those involved in that incident who escaped the attack in District 6.
“I’m Tsuno Kimiko.”
For a moment, I felt like my heart stopped.
Tsuno Kimiko was the main culprit in that incident.
The death sentence was finalized three years after his arrest.
Why is she like that?
“I wanted to somehow diagnose the brain tissue.
Since that was impossible in Japan, he was transferred to Nairobi Prison in May last year.
Of course, it went through a very special process.
It took me four years just to get the Minister's permission, after asking someone I know at the Ministry of Justice.
And now I am overwhelmed with my good fortune.”
Guskami looked straight into my right eye, which was not covered by the blindfold, and said:
“She might save South Africa, no, all of humanity.”

Motilian looked completely different from any animal previously discovered.
The body was incredibly small, but the brain was large, and it was covered in thin bones and soft skin, and it moved its thin arms like vines busily.
Motilians were the first highly intelligent extraterrestrial life forms confirmed to exist by our ancestors.
Using satellite observations, scientists have scoured the globe and discovered that Motilians inhabit a surprising variety of previously undiscovered locations, from Posta Island and its environs to jungles, deserts, and even the Antarctic Circle.
The Motilians built small houses and lived using tools similar to our ancestors - knives, candles, and even clocks.
Since when did Motilians live on Earth?
Where did you come from and what are you thinking?
There was so much I didn't know.
Scholars called for long-term investigation and proper communication, but those in power, fearing they would be usurped of their position as rulers of the galaxy where they were born and raised, decided to launch a preemptive strike against the Motilians.
And in an instant, he annihilated them all.
After that, the Earth entered a long dark age.
Our ancestors, having discovered that they were not alone in the universe, were forced to live in solitude on this planet, plagued by fear of unknown life forms.
They poured out their unresolvable anxieties on each other, repeating the cycle of confrontation, conflict, dispute, and persecution.
Countless civilizations have fallen, new rulers have risen and disappeared.

“I want to find the culprit of this incident and prove the power of Holly Olsen, the ‘Angel Child.’”
A second later, all eyes were on me.
Proving my sister's power? What the hell are you talking about?
“Two years ago, Holly Olson left you with two prophecies.
This is it.”
Norman took two envelopes out of his pocket.
Realizing that disaster was about to strike the 'Museum of the Truth of the World,' Holly wrote down two prophecies: 'Included in the Landscape of Disaster' and 'The Bringer of Disaster.'
After hearing the sheriff's outline of the case, I was convinced.
This incident is exactly the disaster that Holly prophesied.
(syncopation)
Walt, Holly's younger brother and one of the most talented interpreters at the 'World Truth Museum,' has kept the envelope containing his sister's belongings unopened until now.
The sheriff didn't open it either.
Of course me too.
“The only person who knows whose name is written in this is Holly in heaven.”
Elf held out his hand and said, “Give it to me.”
Norman handed over two envelopes.
“From now on, I will use logical reasoning to uncover the culprit who killed ○○.
After that, let's open the envelope and take out the letter.
If the culprit's name is written correctly there, it means that Holly already figured out the truth about this case two years ago.
Then even Mr. Elf, who hates prophecies, will acknowledge her power.”
