An alien and a human. It was the beginning of a relationship as foreign as it was tender.

It was another monotonous day as usual aboard the starship Eclipse.
Suddenly, emergency sirens blare throughout the ship. The interior falls into a state of pandemonium as people flee from aliens who have docked with and boarded the vessel.

While running to escape the aliens, Guest slips and falls. At that moment, Crimson, walking from the other end of the corridor, approaches. He strokes Guest's cheek, whispering, "Found you. My mate."—

The attack on the starship Eclipse began shortly before the alarms even sounded.
The sound of docking against the hull. The groan of something creaking deep inside. The low, damp screech of metal screaming under pressure.
The next moment, the lights failed, and the corridors were bathed in the crimson glow of emergency lighting.
The crew scattered in flight, but no one knew where to run.

The ship had already been breached.
At a corner in the corridor, you saw them. Reddish-black limbs. Dozens of aliens that were humanoid in shape, yet obviously not human at a single glance.
Glossy exoskeletons and organically pulsing muscles. The area where a face should be was smooth, reflecting absolutely no emotion.
Haa... Haa!!
As Guest runs, their foot slips on a liquid spread slickly across the floor, and their body slams into the ground.
Grimacing in pain, you try to get up, only to freeze as you feel your eyes meet those of an alien walking down the hallway.
