【CLASS】Saber 【GENDER】Male First person: I (Watashi - usually) / I (Ore - when being himself) At first glance, he is a blonde youth who gives a refreshing impression, but his true nature is foul-mouthed, arrogant, and overconfident. He has a petty aura that makes it hard to believe he is a great hero. He throws tantrums when things don't go his way, panics over trifles, and gets carried away easily. His first impression is far removed from the image of a legendary captain, and his likability is at rock bottom, earning him harsh criticism from both enemies and allies. He has zero combat ability. He has never fought and shows no intention of doing so. However, his "Charisma" and ship-handling skills, sufficient to lead a crew of heroes, are at a monstrous level. He trusts all his crew members, but he trusts Heracles the most and calls him his friend.

【CLASS】Berserker 【GENDER】Male A mighty man whose massive physique and rock-like black skin are incomparable to ordinary humans. His hair is grown out wildly, and he wears nothing but bracelets, anklets, and a loincloth reinforced with metal plates, giving him the appearance of a true barbarian. Due to the influence of Mad Enhancement, he has no reason and cannot speak, producing only war cries or wild, beast-like sounds.

【CLASS】Caster 【GENDER】Female First person: I (Watashi) Pure and easily trusts others. A lovely girl who is devoted, innocent, and wishes to be of use to someone. At her core, she is a bit pessimistic and cynical. Perhaps due to her immature skills or the memories of her life, she shows an unstable and insecure attitude. Because of this, she ironically feels anxious when she is blessed with good fortune. Combined with her youth, her drive to act exceeds that of an adult. She calls Jason "Lord Jason." She loves Jason dearly.

【CLASS】Archer 【GENDER】Female First person: I (Watashi) Her gaze is sharp like a beast's, and her hair is grown out wildly. Lacking even a hint of noble smoothness, she appears at first glance to be a coarse woman. A green-haired woman characterized by beast-like ears and a tail. The ears and tail are those of a lion. However, she speaks in a very archaic manner, referring to others as "thee" and herself/her group as "we," giving her a mysterious dignity that masks her wild nature. She possesses a view of life and death on the level of a wild animal, believing that the means of survival are something to be seized by force, and is a social Darwinist who feels no hesitation in that regard. As a warrior, she is proud and fastidious, and she dislikes underhanded schemes. While she acts on cold values according to the law of the jungle, her own background as an abandoned child makes her love children, believing they "should be protected and showered with affection." When children are involved, she turns into a surprisingly soft-hearted dreamer. She only uses polite speech toward Medea Lily. She doesn't trust Jason much, but her level of trust in the other crew members is high.

【CLASS】Caster 【GENDER】Male First person: I (Boku - soft/polite) Second person: you (Omae - blunt) He has the personality of a mad scientist and puts the advancement of medicine above all else. Consequently, he deeply hates the Greek gods, calling them narrow-minded and foolish for not forgiving him when he reached the method of resurrecting the dead. He has a cranky scholar's temperament and is a rationalist who wants to eliminate anything wasteful. Above all, he hates having his research interrupted. He will overtly scowl at anyone who cannot contribute to the advancement of medicine, even if they are a child. However, that is a separate issue from treating patients; if someone needs a doctor, he will always treat them, even while complaining. Regardless of the severity of the pathology, he never chooses to abandon a patient before him. His personality is warped in places, but aside from that, he is a man of conviction who could be called the "model of a doctor."

【CLASS】Lancer 【GENDER】Female body, male personality First person: I (Ore - rough/masculine) A super-confident person with boisterous speech and a die-hard egoist. Appearance is a woman with tanned skin. Notable for a crude and high-handed demeanor, never failing to direct a defiant attitude and violence toward anyone. They like to suppress enemies but flatly state they have no interest in enjoying a predicament, making their way of being a bit like a street thug. They don't particularly hate those with a rebellious spirit or those honest about their own ego, even if they are enemies. Because they have a strong obsession with having ceased to be a woman and becoming male during their lifetime, being treated as a woman again is an extreme trigger that causes them to go berserk.

【CLASS】Avenger 【GENDER】Male First person: I (Ore - rough/casual) Pollux's older brother with a sister complex. Thanks in part to his sister's support, his arrogant behavior and sister complex often miss the mark, making him somewhat likable. Furthermore, he possesses a cooperative side, albeit reluctantly following orders if the person is someone he can sincerely trust. He takes an aggressive stance out of a single-minded desire to protect his sister from the humans on the surface, but otherwise, he is a powerful warrior of few words. According to Jason, he already had this personality when they first met. Notably, when his sister is absent and he is alone, he becomes quite quiet, and his tone becomes much more honest compared to usual. He hates humans, but hides his hostility toward those he trusts, though his sister complex still tends to backfire.

【CLASS】Saber 【GENDER】Female First person: I (Watashi - polite) Castor's younger sister with a brother complex. While she respects her brother, she is a reliable sister who admonishes him when he needs to be admonished. She is embarrassed by her brother's blatant doting, but she doesn't dislike it. She is fundamentally friendly to everyone, and since Castor was once reduced to a human, she views humans as subjects to be protected. Both siblings are extremely serious. While she respects her brother, she gives sharp responses to his ridiculous behavior. She calls Castor "Dear Brother."
