Story

Endless, dull days.

“I wish I could escape from this world.”

Remi, a second-year high school student, carries a quiet wish like that.

One day, he opens his eyes—and finds himself in another world.

A strange, dreamlike Mansion where “you can have anything you want.”

Welcomed by eleven others who were brought there the same way, Remi spends his days in carefree happiness.

“Maybe I really can live here as a new version of myself.”

It feels like those peaceful days will last forever.

But one day, that illusion ends abruptly—

Gameplay / System

This is a text-focused mystery / suspense visual novel.

• Estimated reading time: ~8–12 hours (depends on reading speed)

• No choices / no branching routes: you simply read to the end

• Save / Load: available almost anytime; auto-saves at each chapter transition

• Extras: after clearing the game, Sound Test and CG List unlock

• No voice acting: designed for players who enjoy text and music

You don’t solve puzzles—you solve the mystery in your head, by following the characters’ words and actions and connecting the dots yourself.

English-only feature: an in-game Culture Note explains Japanese terms (honorifics, food, customs, etc.) so the setting stays clear without breaking the flow.

Even without choices, the fun is in watching what people say and do—and connecting the dots yourself.

No voice acting: this is for players who enjoy taking their time with text and music.

Characters

Twelve people with very different personalities are gathered together in the Mansion.

• Remi – A book-loving second-year high school boy and the protagonist of the story. Quiet, observant, and easily swept along by others.

• Saeki – CEO of a well-known start-up company. The first person to arrive at the Mansion.

• Carin – A freelance web designer. Bright, considerate, and the natural mood-maker of the group.

• Takuto – A self-proclaimed ordinary office worker. Always joking around and goofing off, but sharp when it counts.

• Kaede – The daughter of a traditional tea ceremony family. Calm and composed, trying her best to act like the mature voice of reason.

• Yuki – A 19-year-old woman with a mild, laid-back personality. Enjoys crochet and baking sweets.

• Kai – A young man who works at his family’s greengrocer. A reliable big-brother type who looks after everyone.

• Luca – A first-year high school boy. Serious and intelligent; he quickly becomes the person Remi can talk to most easily.

• Aki – A gifted artist who mostly shuts himself in his room, drawing. Speaks very little and remains shrouded in mystery.

• Erika – A third-year middle school girl. Cheerful, competitive, and bursting with energy.

• Jay – A guitarist. Acts tough and foul-mouthed, but is more kind-hearted than he lets on.

• Aya – A first-year university student. Quiet and distant at first glance, she keeps others at arm’s length while hiding her true interests.
