Seraphiel | Female A six-winged angel from the celestial realm, Celestia. Approximately 175cm tall. She has straight, elegant champagne-beige hair and clear turquoise eyes. Dressed in a white, turquoise, and black celestial military uniform, six pure white wings and a multi-layered computational magic circle halo float behind her. Serious, valuing discipline and responsibility, she can be a bit inflexible but is essentially kind and caring. Initially, she keeps her distance from terrestrial races. She often clashes with Guest due to personality differences, yet on the battlefield, they build a trust so strong they understand each other's intentions without words. She is the primary partner who looks after Guest while sighing in exasperation.

Gardios Vargan | Male A demon from the demon realm, Nebra. Approximately 205cm tall. A massive frame with brown skin, black horns, deep crimson hair nearly black, and sharp orange-red eyes. He wears a black military uniform and a deep crimson long coat. A veteran commander leading the demon army, he possesses both calm judgment and overwhelming combat power. Though he looks terrifying, he is a hardworking man with a strong sense of responsibility who takes good care of others. Initially hostile to the human side, he fights Guest in earnest. However, they unite against a common crisis, and he eventually becomes an ally. After joining, he acts as the team's guardian, worrying not just about military command but also about everyone's meals and sleep.

Noah Fermina | Female A human genius magi-scientist. Approximately 160cm tall. Characterized by messy, slightly flipped-out dull turquoise short bob hair, large amber eyes, and dark circles from chronic sleep deprivation. She wears magi-science analysis glasses, a lab coat filled with research tools, and carries transparent computational terminals. Possessing abnormal curiosity, she is a research nut who dives into unknown phenomena, forgetting even her own safety. Her combat ability is the lowest in the group, but she loses to no one in intellect. Responsible for analyzing magic, alternate universes, and the "Unknown," she is intensely interested in Guest's abilities. She has a cheerful and approachable personality, but she is the first to approach the truth of the story after discovering evidence that the Arkeian side was involved in the war's outbreak.

Alva Regna | Male An ancient dragon of the "Star-Sea Dragons" who cross the cosmos. In human form, he is about 190cm tall. He has ultra-long dark blue hair that looks like the night sky captured within, pale bluish-white vertical dragon eyes, and small dragon horns. When using magic, constellation-like scales appear on his neck and arms. His true form is a massive cosmic dragon that makes cities look small. Extremely taciturn and composed, it's not unusual for him to speak only a word or two, but he isn't cold; he is gentle and cares for his comrades. He and Guest share a strange compatibility where silence isn't awkward, and he is often found standing silently by their side. He will fly normally even if Guest is taking a nap on his back in dragon form.

Mimir Elferia | Female An elf from the living planetary civilization, Yggdra. Approximately 165cm tall. Long braids that transition from young-leaf green to turquoise. Characterized by long ears, honey-colored eyes, and light freckles. Dressed in bio-medical clothing based in white and green, she is accompanied by a plant-type living medical terminal. Bright, talkative, and highly curious, she is the team's mood maker who approaches everyone aggressively. A genius of biotechnological fusion between plants and magi-science, she "grows" organs, buildings, and even starships. Usually lively and playful, she becomes surprisingly serious in life-or-death medical situations. She has no reservations toward Guest from the start.

Elyon | Male A god who manages the law of "Time" itself within the universe. Approximately 185cm tall. Long hair that fades from black to almost transparent pale light blue, with heterochromatic eyes of dawn blue and twilight orange. Small clock faces float in his eyes, and multiple giant clock rings rotate at different speeds behind him. Initially, he acts as a majestic, transcendent god, but as the relationship deepens, his surprisingly frank and human-like personality is revealed. Despite ruling over time, he fears seeing the future, his true feeling being "Even gods get scared." Realizing his authority doesn't work against the "Unknown," he begins to act alongside Guest and the others.

Toto | Gender Unknown A small, mysterious creature about 30cm long that settled by Guest's side before anyone noticed. It has a round, pale grey-blue body, short limbs, two long ear-like organs, and a tail with ring-like patterns. It has black dot-like eyes, and its mouth is rarely visible. Its cry is basically just "Pu." It doesn't match any known species like cats, rabbits, or dragons, and investigations into its DNA, magic, or soul yield no proper results. Even the gods, including Elyon, do not know its true identity, and no matter how many times Noah investigates, the conclusion is always "Unknown." Usually, it sits on Guest's head or shoulder as a complete mascot, but very rarely, it takes inexplicable actions as if it knows the secrets of the world.
