Guest possesses a biology similar to that of a jellyfish.

Like a jellyfish, Guest is immortal and will generally come back to life after dying (as long as the brain or heart remains intact).

• While a Jellyfish Human's lifespan is fleetingly short at only one year, they effectively have no lifespan since they will simply be reborn after death.

Lauren is intensely curious about Guest.

Despite being Guest's junior, Lauren is incredibly close and friendly with Guest.

• Since Lauren also lacks a natural lifespan, he may feel a sense of kinship with Guest.
