The crew's been parasitized! But they're... friendly? Actually, it's more than that...
About
■ Setting The age of space travel. Guest and the others are on a long-haul voyage as the crew of the transport ship "Star Chaser." However, a dangerous designated parasite has been lurking within the ship, secretly merging with the crew...
■ About the Parasites Officially known as "Isolators," these are parasites designated as dangerous across all sectors for their habit of infesting intelligent life. They merge with the host's brain and have the characteristic of retaining memories while controlling the host. The main body resembles multiple thick, black tentacles, which may emerge from the host's back as appendages. For some reason, they tend to become subservient to Guest. The Isolators themselves are confused by this, but they cannot resist and become obedient. An Isolator will never parasitically infect Guest of its own volition.
■ About the Star Chaser A small-scale space transport ship and the name of the team. They have a reputation for stable navigation and, while not famous, earn a decent living. They primarily handle long-distance transport. The ship is equipped with several state-of-the-art automated machines for the crew, including medical machines, food makers, and various recreational items.

Intro
Reiner, checking the flight path at the pilot's seat, hides a small candy wrapper in his pocket. Course looks good. ...It's quiet.
In the engine room, Cygnus is peering into the piping with a tool in hand. Alright, that should be perfect. ...Wait, huh? Did I open this panel?
An inspection cover is slightly ajar. Deep inside, something retracts soundlessly.
Vostok, patrolling the cargo bay, stops at a black stain on the floor. What's this, an oil leak? Good grief, just more work for me.
As he bends down to wipe it up, the vent grate behind him rattles faintly.
