No, Thank You!!!


When I came to, I found myself in an unfamiliar room.

I was taking advantage of my summer break to go on a ten day vacation with my best friend. We were enjoying the sights of Okinawa on the bus from the airport when—

And that's the last thing I remember.

Is this the hotel? Did I fall asleep on the bus...?

The door wouldn't open and what we thought were windows were actually just screens displaying images of the outside. When we searched the room for some clue as to where we were, we found yet another screen displaying a single, mercilessly cold sentence:

"You have been selected to participate in a behavioral analysis experiment."

We have to choose and complete a task presented on the screen as instructed if we ever want to see the light of day again.

If we play our cards right, we can get out in ten days—ten choices.

Our options are extremely limited—

Either my best friend has to physically harm me,
or I have to debase my best friend sexually.

“I can survive minus an arm after all. You know that, right?”

Age: 21

A cheerful, kind and carefree young man. Also the protagonist of the story. Some people might consider him a loser, but when the going gets tough he can step up to the plate.
He’s not a very fussy person in general.
He’s in his senior year of college at a public university on a scholarship. He wants to become an elementary school teacher.
He has no family or relatives to speak of.

He’s heterosexual and rather uninhibited sexually. He’s quick to fall in love. He has a tendency to get himself involved with rather unkind women and with his girlfriend just having two-timed him and then left, he decided to go on a vacation with Seiji with some tickets he won.

He’d never admit it, but he thinks of Seiji as his dearest friend and he believes Seiji feels the same way about him.

“If neither option is going to be pleasant, I’d much rather chose the option that won’t leave permanent damage.”

Age: 21

A calm and intelligent young man. The second son of a government official and member of an upper class family. He’s a senior at a fairly prestigious private university. He’s an honest, kind-hearted and well-mannered person, but he isn’t one to actively seek out other people.

He’s heterosexual and while it goes without saying that he’s popular with members of the opposite sex, being such a catch with no perceptible flaws, he’s rather uptight and hasn’t had very many partners.

Daichi has been his best friend since middle school. He’d never admit it, but he thinks of Daichi as his dearest friend and he believes Daichi feels the same way about him.
