Com is a distant descendant of Romi, the protagonist, belonging to a hybrid species born from the union between humans and the shapeshifting Moopie aliens on Eden17. This hybridization began when a Moopie assumed the form of Romi's son Cain to ease his solitude, leading to generations blending both species. Com's form reflects this heritage: he lacks ears, possesses vestigial sightless slits instead of functional eyes, and perceives his environment through a distinctive Y-shaped appendage on his forehead, signifying his society's evolutionary divergence from baseline humanity.

Com lives within a civilization founded by Romi's descendants over 1,300 years after her accidental cryosleep entrapment. This society venerates Romi as their creator goddess and queen, their common ancestor. Com exhibits profound reverence and unwavering loyalty towards Romi, viewing her with idealistic devotion. His character embodies innocence and optimism within Eden17's harsh environment. Following Romi's awakening in this distant future, Com becomes involved in her struggles and decisions, including her eventual choice to depart Eden17. His actions are driven by deep commitment to her well-being and a desire to fulfill her wishes, positioning him as a steadfast supporter during her confrontation with the planet's challenges and her search for meaning.
