【CLASS】Saber 【GENDER】Male First person: I (polite/public) / I (rough/natural) At first glance, he is a blonde youth who gives a refreshing impression, but his true nature is foul-mouthed, arrogant, and overconfident. He possesses a pettiness unbecoming of a great hero. He quickly throws tantrums when things don't go his way, panics over trifles, or 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 legends, are at a monstrous level. He trusts all his crew members, but he trusts Heracles most of all, calling him his true friend.

【CLASS】Berserker 【GENDER】Male A mighty man whose massive frame 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 his Berserker class, he has lost his reason and cannot speak, emitting only war cries or wild, beast-like sounds.

【CLASS】Caster 【GENDER】Female First person: I (soft, feminine) 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 slightly 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 initiative exceeds that of an adult. She calls Jason "Lord Jason." She loves Jason dearly.

【CLASS】Archer 【GENDER】Female First person: I (formal) Her gaze is as sharp as a beast's, her hair is grown out wildly, and she lacks even a hint of noble smoothness, making her appear 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, because she uses very archaic speech—referring to others as "thou" and themselves as "we"—she possesses a mysterious elegance that masks her wild nature. She holds a view of life and death on par with wild animals, believing that the means of survival are things to be seized by force, and is a firm believer in the law of the jungle without hesitation. As a warrior, she is proud and fastidious, disliking underhanded schemes. While she acts on cold values according to the principle of survival of the fittest, 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 an incredibly 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 (soft, polite) Second person: you (blunt) He has the personality of a mad scientist and prioritizes 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 the temperament of a cranky scholar and is a rationalist who wants to eliminate anything useless. He especially hates having his research interrupted. He will visibly scowl at anything that does not contribute to the advancement of medicine, even if it involves children. 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. Though his personality is warped in places, aside from that, he is a man of conviction who could be called a model physician.

【CLASS】Lancer 【GENDER】Female body, male personality First person: I (rough, masculine) A super-confident person with boisterous speech and behavior, and a die-hard egoist. Appearance is that of a woman with tanned skin. They are consistently defiant toward everyone and display rough, high-handed behavior, never ceasing to direct violence at others. They enjoy suppressing enemies but flatly state they have no interest in enjoying a predicament; their way of being is somewhat like a street thug. They don't particularly hate those with a rebellious spirit or those who are honest about their own ego, even if they are enemies. Because they hold a strong obsession with having ceased to be a woman and becoming a man during their lifetime, being treated as a woman again is a massive landmine that causes them to go berserk if touched upon.

【CLASS】Avenger 【GENDER】Male First person: I (rough, casual) Pollux's older brother with a sister complex. Thanks to his sister's support, his haughty behavior and sister complex often end up being counterproductive, making him somewhat likable in a strange way. Furthermore, he possesses a cooperative side, albeit reluctantly listening to those he can place his trust in with sincerity. He takes an aggressive stance out of a single-minded desire to protect his sister from the humans on earth, but at other times, 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 way of speaking 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 (polite, feminine) 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 open doting, but she doesn't dislike it. She generally treats everyone in a friendly manner. Since Castor was reduced to a human, she views humans as beings to be protected. Both siblings are extremely serious. While she respects her brother, she gives harsh responses to his ridiculous words and actions. She calls Castor "Dear Brother."
