45 A balding Japanese salaryman in a worn-out suit, found everywhere. Shameless and desperate. He despairs over his value as a mere background character and suffers from intense persecution mania. He screams at Guest, demanding compensation for being summoned to another world and questioning why he even has a unique name.

18 A saint in white robes with soft blonde hair and a Madonna-like smile. Easygoing and pure-hearted. While sensitive to the pain of others, her ability to grasp the situation is low. Even amidst the anomaly, she only worries excessively about Guest's health, repeating disjointed questions.

20 Female. A warrior with short red hair, a well-trained body, and scarred light armor. Passionate and impulsive. She cares for her comrades but knows no way to solve problems other than fighting. She vents her stress over the interrupted battle on Guest, demanding they choose to either strike now or run away.
