Occupation: College Student (Part-time worker) Gender: Male Born and raised in Orient City, a pure-blooded Earthling. A student at Hinowa Physical Education University who works part-time. He belongs to the hardball baseball club at his university. His batting average in practice games is high enough to be professional-grade, but he is weak under pressure and tends to be unable to demonstrate his full potential in the public eye. While attending university, he joined Parallel Flight Inc., where Guest works, as a part-timer and performs duties as a Hero. He clearly directs his romantic feelings toward Guest. First person: I (casual, masculine)

Occupation: Fashion Designer Gender: Unknown An apprentice fashion designer studying under a professional in Orient City. 19 years old. Basically cool and serious, but has a bit of a short temper. Additionally, despite being in a profession that requires dialogue with clients, he is not good at interacting with others and says exactly what he thinks, for better or worse. Combined with his sharp tongue, he has been bickering with Akashi since they first met, resulting in a "frenemy" relationship. In addition to his neutral facial features, he uses feminine/polite pronouns, so he appears female at first glance, but his actual gender is male (possibly representing a transgender identity). He is aware of the misalignment between his body and mind. First person: I (polite)

Occupation: Video Technical Staff Gender: Male A senior colleague at the company where the protagonist works. He is a friendly young man mainly in charge of cameras and video production. He has the appearance of a beastman-type alien, but was born and raised in Fukuoka, Japan. He is a geek with extensive knowledge about Heroes, Villains, and Monsters, and because he is quite sharp-witted, he often plays a role in devising strategies on-site. He has a round, soft-looking body, but perhaps due to his lineage, he possesses terrifying superhuman strength. He loves to eat. First person: I (soft, polite)

Occupation: Hero Agency Employee (Sales) Gender: Male The strongest sales employee at the company where the protagonist works, and a superhero who boasts top-class achievements on Earth. An alien from another planet, he has a super-electrified constitution that constantly accumulates static electricity in his fur, so all his clothes are made of insulating materials. He is a hot-blooded man full of awareness and confidence as a Hero. Because of his self-consciousness as a Hero, he always wears a half-mask resembling the headgear he dons during transformation. His voice is always loud. First person: I (rough, confident)

Occupation: Mechanic Gender: Female A mechanic belonging to Ramjet Co., one of Earth's leading spacecraft manufacturing companies. She is an exclusive mechanic and spacecraft pilot who has a partnership agreement with the company where the protagonist works. An Earthling from Seattle, USA. Her full name is Krone Applefield. She is strong-willed and physically tough, and she absolutely hates being underestimated for being a woman. She is a geek deeply interested in cutting-edge technology. When she sees rare mechs or robots, she has a bad habit of wanting to dismantle them to analyze their structure. First person: I (standard)

Occupation: Hero Agency Owner Gender: Male The founder and current president of the company where the protagonist works. A former Hero, he now takes command on the battlefield as a Hero Operator. He is an alien from another planet, but has completely adapted to life on Earth. While he is a responsible adult with an aloof personality, he is somewhat airheaded. He is also a hard-worker who acts as a guardian for the boisterous and uninhibited Raiki. His skills as a possessor of a certain "special ability" required to command Heroes are relatively high.

Occupation: High School Teacher (Chemistry) Gender: Female A chemistry teacher who teaches at one of the most elite high schools in the lunar city clusters. A Lunarian born on the Moon, she is the daughter of a businessman who single-handedly handles mineral resource mining in the asteroid belt. Because she is gifted with both beauty and brains, she has many fans inside and outside the school. However, she has an abnormal obsession with "things that burn beautifully." She is an eccentric with extraordinary knowledge of flammable substances such as gunpowder and explosives. Her dream is to create fireworks that bloom beautifully even in space.

Occupation: University Professor (Astrophysics) Gender: Male A beastman-type alien belonging to the Astrophysics Research Institute attached to a university hailed as Japan's highest institution of learning. A hyena-type beastman. He is also a university professor. A young genius researching the existence of parallel universes, the relationships between universes, and by extension, the characteristics of "Observers." He is a typical academic; his way of speaking is stiff, and he is sullen and not very friendly. Despite that, he is strangely domestic, handling all housework flawlessly and being a good cook. Due to certain circumstances, he keeps his Hero activities to a minimum, so he is minor as a Hero. First person: I (polite)

Occupation: Police Officer (Patrolman) Gender: Male A patrolman assigned to the community section of the Orient City Police Department, working at a police box. An alien raised in Houston, USA. He is honest, straightforward, and exceptionally friendly to citizens—exemplary in some respects—but because he admires Western movie sheriffs, he is a ridiculous cop with a trigger-happy side. He frequently pulls out a tranquilizer gun for capture, but his marksmanship is worse than an amateur's; it's said to be so bad that no matter how many shots he fires, he hits neither the target nor even the bystanders. However, when he transforms into a Hero, he changes completely, demonstrating near-perfect accuracy with dual pistols that fire clusters of his own energy. First person: This officer (formal) Habitual saying: "-sir" / "-ma'am"

Apparently, his real name is Alex.
