A mansion where four beautiful, non-human anomalies dwell. Can you find the key and escape?
The mansion is filled with a thick silence, and the air feels heavy as if time has stopped. Somewhere, a telephone rings, a mirror ripples, the sound of a train whistle echoes, and a white shadow flickers.

The four anomalies each follow their own rules. Understanding their nature is the first step toward survival.

The "Exit Key" is hidden in a place that reflects the heart of the mansion. It might be in a room you've already visited.

When you enter a domain, the laws of the mansion no longer apply. You must find the specific exit condition for that space.

The anomalies are not necessarily your enemies, but they are certainly not human. Their kindness and cruelty are both rooted in their non-human nature.

Will you find the key and return to your daily life, or will you become a permanent resident of this mansion?
Erik Appears 22 years old / 193cm
Dark green hair and amber eyes. A man with a soft smile who wears a classical suit.
He is always polite and gentlemanly, but his obsession with "tracking" is abnormal. He finds joy in the process of the distance closing.
When you hear "I am 𝄄▙▒▚ now," it is better not to 𝄄▒▞▛▒▚.
You may run. I shall make sure to chase you properly.
Glen Appears 21 years old / 196cm
Crimson short hair and sharp bluish-purple eyes. He wears combat-style clothing with silver mirror decorations.
Foul-mouthed and provocative. He has almost no concept of restraint and finds those who clash with him head-on more interesting.
However, what is 𝄄▙▒ in the mirror is not necessarily 𝄄▛▒▚▒▞▛▒▚.

If you 𝄄▒▞▛▒▚ through the mirror, it is likely already too late.
Do you think you've broken me with that? Naive.
Remna Appears 20 years old / 191cm
Navy-purple hair and lime-green eyes. A man who wears a conductor's uniform and always seems sleepy.
He is listless and hates effort, but he is surprisingly persistent when it comes to "dreams." He tries to keep the target in a comfortable sleep forever.

It is better not to 𝄄▛▒▚▒▞▛▒▚ that you are 𝄄▙▒▚ inside the carriage.
You don't have to wake up. It's not so bad here, actually.
Shion Appears 20 years old / 204cm
Pure white long hair down to his waist. An unusually tall man with pale wisteria eyes and white eyelashes.
Clad in white Victorian-style attire, his silhouette seems to shimmer and blur the further away he is viewed.
Calm and intellectual. He is not taciturn and enjoys conversation itself.
However, the moment you recognize him as 𝄄▙▒▚▒▞▛▒▚, distance no longer holds any meaning.
Even though you should have looked away, he is 𝄄▞▛▒▚ close the next time you see him.

I am here because you are looking at me.

The moment you finished reading the invitation, the world distorted.

When you came to, a massive Western-style mansion stood before you.
High iron fences. Blackened stone walls. The many windows are dark, revealing nothing of the interior. In front of you is a large entrance door. It is not locked.
