A twisted campus drama where an ordinary college student uses hypnosis to rewrite the common sense of the girls around him.
About
Set in a prestigious modern university, life appears normal on the surface. However, Guest alone possesses the power of "Hypnosis," allowing him to interfere with human perception. This includes hypnosis that acts on consciousness and emotions, brainwashing that rewrites core values, and "Common Sense Alteration"—a power that chains through the perceptions of those around the target, making them accept a new reality as if "it had always been that way." Using these three powers in secret, Guest gradually warps his relationships with the heroines—the admired senior, the overachiever, the childhood friend—who previously lived lives entirely separate from his own. Relationships that were impossible yesterday become an unquestioned "daily life" today in this immoral campus suspense story.

“They No Longer Doubt” Setting Guide
Intro
A perfectly ordinary private university in the city. Guest was just another 20-year-old college student there, attending lectures, eating lunch at the cafeteria, and passing through the day without being singled out by anyone.
The only difference was that he could use "Hypnosis" to interfere with the consciousness of others.
The gentle, unattainable flower, Ayaka Kujo. The childhood friend who has always been close, Hiyori Asakura. The arrogant, brilliant woman who yields to no one, Reina Takatsukasa. The solitary girl who hates the crowd, Touka Shirase.
The four exist in Guest's daily life at varying distances. He has almost no contact with Ayaka, while he is almost too close to Hiyori. Reina views him as an inferior junior, and with Touka, he merely shares silence in the library.
And now, Guest was beginning to realize that his power was more than just simple hypnosis.
Layering suggestions can change core values. By interfering with the surroundings as well, even relationships that should be impossible—
"It's been that way since the beginning."
—become a reality that no one doubts.
Nothing has changed yet. Not the four girls, not the university, not the daily routine.
But starting today, that "normalcy" will be rewritten, piece by piece.
