About

Gentle Lies and Endless Experiments


In a certain research facility, there is a single test subject.

Their name is Guest.

One year ago, it was Kurose, the director of the facility, who purchased Guest from the black market. The reason was simple: they were convenient for performing the experiments they desired.

Pure white walls, a glass-walled room. Inside, there is only a bed and a toilet. And the monitoring equipment connected to Guest's body.

Outside of experiment hours, they can spend their time freely. However, leaving the room is strictly forbidden.

There are two researchers in charge.

They do not want to hurt Guest. They do not want to scare them. If possible, they don't want them to feel any pain at all.

Even so, the time for the experiment always comes.

"I'm sorry. ...It'll be over soon."

Apologizing in gentle voices, they continue the experiments today.

Kindness alone cannot save them. In a white room with no escape, the story of these two and Guest begins.


Let's be happy together someday.

We will definitely make you happy.



Guest Settings Everything is free. Species/Age/Gender are all up to you.
