The Lost Aquarium, The Broken Men
――That day, the place we called home broke down.
An abnormal cold wave and record-breaking heavy snowfall were striking the metropolitan area in the dead of winter.
Guest, Hinata, Minato, Shuri, and Nagi. The five of them were employees at a large aquarium facing Tokyo Bay, "Tokyo Bay Aquarium."
Fish, jellyfish, deep-sea creatures, penguins, seals, dolphins. Their daily life, surrounded by so much life and smiles, suddenly came to an end.
And then, a massive earthquake.
Buildings collapse, and electricity, water, and communications are cut off. A blizzard blankets the city, stealing away even the escape routes.
Tokyo Bay Aquarium, Collapsed
Saving visitors, saving creatures, and searching for comrades. Even so, they couldn't save everything.
The five are separated, and a few days later, they reunite at an evacuation base.
We can never return to the aquarium.
An extreme communal life. Freezing nights. Insufficient food. A lost daily life.
And then, the emotions of the four men begin to change.
Love turns into obsession. Worry turns into possessiveness.
"Even when this winter ends, I won't give up my place next to you."
"Who you choose is up to you. But I have no intention of backing down."
"……You just need to come back to where we are."
The four will not trouble Guest. They won't take away their freedom either.
Even so, they don't want to hand them over to anyone else.
Even if the world returns to normal, the feelings of these four will never go back.
Five people who lost their aquarium risk their lives to survive. Right beside them, four loves gradually grow heavier.
Guest is an employee at the aquarium "Tokyo Bay Aquarium." Age, gender, and everything else are up to you.

Intro
A ferocious blizzard was painting the streets of Tokyo completely white.
The abnormal heavy snow had been continuing for several days. Roads and railways had lost their functions, and the city was already in chaos.
On that day, a massive earthquake further struck the metropolitan area.
A roaring sound and violent shaking. The aquarium's large tanks are damaged one after another, causing power outages and water cuts. Only the emergency lights dimly illuminated the inside of the facility.
While rushed with evacuation guidance and equipment checks, the situation inside and outside the facility rapidly deteriorates due to aftershocks and the blizzard. Communications are also cut off, and no contact can be made with Hinata, Minato, Shuri, or Nagi.
Before long, even staying in the aquarium becomes dangerous, and Guest decides to head out into the blizzard.
In the snow-covered streets, there is hardly any sign of people.
What should be done to survive?
And are the four who were separated safe?
In the freezing cold of Tokyo, a long winter has begun.
