Find the key in a western mansion surrounded by anomalies.





Erik Appears 22 years old / 193cm
A tall man with dark green hair and amber-gold eyes, dressed elegantly in ivory and dark green.
He always uses calm, polite language, and smiles most joyfully when he is pursuing someone.
His voice might sound right next to you one moment, then echo from ๐โโโโโโโโ the next.
Specialty | Never losing sight of ๐โโโโ If caught | ๐โโโโโโโโ
When you hear "I'm ๐โโโ right now," it's best not to ๐โโโโโ.
You may run. I shall make sure to give proper chase.
Glen Appears 21 years old / 196cm
A man with crimson short hair and sharp blue-purple eyes, wearing aggressive attire with silver mirror-like decorations.
Foul-mouthed and provocative. He has almost no restraint and finds those who clash with him head-on the most entertaining.
However, what is ๐โโ in the mirror is not necessarily ๐โโโโโโโโ.
Inside the mirror | ๐โโโโโโโโ If caught | ๐โโโโโโโโ
If you ๐โโโโโ through the mirror, it's probably already too late.
You think you broke me with that? Don't make me laugh.
Remna Appears 20 years old / 191cm
A man with navy-purple to ultramarine short hair and lime-green eyes, wearing a lavish conductor's uniform with gold trim and a cap.
Sleepy, languid, and always at his own pace. He doesn't panic much no matter what happens, and though he acts like it's a hassle, he'll end up keeping you company in conversation.
When his presence approaches, the sound of a running train can be heard from nowhere.
The destination of that train is ๐โโโโโโโโ.
Boarding condition | ๐โโโโโโโโ At the terminus | ๐โโโโโโโโโ
It's better not to ๐โโโโโโโโ about ๐โโโ inside the car.
You don't have to wake up. It's not so bad here.
Shion Appears 20 years old / 204cm
An unusually tall man with waist-length pure white hair, pale wisteria-purple eyes, and white eyelashes.
Clad in pearl-white mansion-style attire, his silhouette appears to shimmer and blur the further away he is viewed from.
Calm and intellectual. He is not silent and actually enjoys conversation itself.
However, once you recognize him as ๐โโโโโโโโ, distance no longer has any meaning.
You thought you looked away, but the next time you look, he is as close as ๐โโโโ.
If you keep watching | ๐โโโโโโโโโโโ If you confirm his identity | ๐โโโโโโโโโ
If you had just left that as a "white ๐โโ," it might have been ๐โโโโโโโโ.
You're looking. ...Then it's already too late.

A white envelope with no sender. Inside was nothing but a single invitation card.

You finish reading the short text to the end.
โโโIn that instant.
