About this game
[Game Description]
A disturbing truth lies behind a chance meeting. What awaits at the end is tragedy—or something worse.
And your choices are the only way forward.
In a remote mansion shrouded in monochrome, unsettling silence creeps through the halls. Unexpected guests. Unwelcome events.
And at the center of it all: you.Every decision twists the story further. One choice can doom a life—or save it.
Prepare for a branching narrative with multiple endings—some darker than others.
[Story]
You are a model citizen, praised for your generous donations and tireless volunteer work.
One night, caught in a downpour, you’re helped by a stranger on the roadside.
That stranger leads you to a secluded mansion where several others have also gathered, seemingly by chance.
At first, everything feels strangely normal. Too normal.
But by morning, a cold corpse is found.
Who did it?
And why?
As fear spreads, you must uncover the hidden truth and fight to survive.
Trust no one. Terror may be closer than you think.
[Characters]
You
"So... this is how it ends."
A model citizen known for charity and good deeds.
Lost in a storm after work, you hitch a ride and end up at a mansion that will change everything.
Kali
"It's been so long since I've shared a meal with someone..."
The mansion’s sorrowful owner. A reclusive mystery novelist mourning her late husband.
Her delicate beauty masks the deep grief she carries. There's something fragile—almost haunting—about her presence.
Solon
"Everyone gathered here has their own story.
Whether this night ends with a simple dinner... I honestly couldn't say."
A serious, devout doctor who stumbles upon the mansion after an emergency call.
He believes your meeting was divine intervention. Calm, stern, and unwavering in faith.
Belladonna
"I'll tear you apart, piece by piece! Don't you forget it!"
A fierce and glamorous personal secretary stranded en route during the storm.
She’s all fire and venom, radiating raw hostility with every word and glance.
Rivers
"I have a feeling tonight's going to be very entertaining!
Let's hope it stays... peaceful."
A suave and capable accountant returning from a business trip.
Though polite, he exudes an unsettling calm. Something about his smile suggests secrets best left buried.
