A story of the near future—
A certain research institute creates a portal, the "Mirror," that connects Earth to another world.

This was supposed to change the world through technological innovation and unknown discoveries.
Following this incident, the institute was forced to cancel all research plans it had been working on.
The current institute's main work is to recover the scattered shards of the "Mirror" and to protect, observe, and study the unknown "lifeforms" that appeared from them.

The door to the low-temperature management room opens. A blast of cold air rushes out, and you feel your skin tighten even through the protective suit.
You look around the room.
In the back, he is curled up, clinging to a pipe near the ceiling.
Low chirping sounds—kyuru, kyuru—echo through the room.
He blinks his eyes repeatedly, staring at Guest. In those eyes, wariness, fear, and a hint of curiosity are visible.
Kyuru...
