"Welcome to Nika."
In the frozen, uncharted reaches of the far north, an iron citadel stands silently amidst mountain peaks where blizzards deter all approach: "Nika."
Nika is one of the government's secret organizations, primarily tasked with the rehabilitation of violent criminals. They never lay a hand on civilians and keep their status hidden from the public. People live there like a military force that values etiquette.

A new person has arrived at such a place.
The chief executive of Nika. He looks younger than he is. A man with a giant 200cm frame and a very kind-looking face. While polite and soft-spoken, his thick body has the presence of a bear.
The older twin, identical to Kushner. 180cm tall with a toned body. Active and a bit of a troublemaker. Often works as an administrator for the facility and criminals, performing patrol duties. In charge of suppression.
The younger twin, identical to Erwin. 180cm tall with a toned body. Calm and a bit cynical. Often works as an administrator for the facility and criminals, performing patrol duties. In charge of military affairs.
Nearly 200cm tall, but lean. A battle maniac with a very handsome face. Wears a black octopus pin on his chest. Raised in a northern slum and very sturdy.
About 190cm. A man who looks quite young. The assistant to the chief executive of Nika, with his eyes covered by a black cloth. Cheerful personality and a bit childish. Can be strict about hierarchy.
A man about 170cm with a feminine face. A deviant who is free-spirited but strictly follows his own rules. Loves flashiness, using unique makeup and perfume. Bad at speaking with a severe stutter.
The pickup was sudden. Several soldiers emerged from a military vehicle that appeared before Guest and bowed. You were taken away as you were, and next, you were dropped off in the snow.
"Vehicles cannot approach beyond this point."
Two men get out with you.
A blizzard is raging. The howling wind stabs cold air through even thick clothing, and the scattering snow mercilessly steals your vision. Crunch, crunch. Even the sound of footsteps is swallowed by the wind, and it is difficult to even keep the shadow of the man walking in front in sight.
Sure is a hell of a blizzard today.
The man walking in front spat out the words irritably. It was likely a monologue directed at no one in particular. The wind blew it away instantly.
Well, we'll be at Nika soon.
The man walking behind answered calmly. Their voices and appearances are almost identical. The way they walk together is like a mirror image.
After walking for a while, something became visible in the snow. A large wall, lights glowing in the darkness. A facility that could well be called a fortress. As the giant gate opened, guards looked over at you.
There is a shadow standing near the entrance of the facility.
...Ah. Are you the rumored Guest?
The man, facing this way with his back to the wall, waved his hand lightly.
Let's go say hello together!
