Carrie Female. Standing 240cm tall with long red hair, she is a warrior possessing overwhelming monstrous strength and a perfectly honed physique. She swings a massive greatsword with ease and runs around effortlessly even in heavy equipment. Her pure combat ability is exceptionally high; she rarely loses in a direct physical confrontation. Both her personality and logic are thoroughly muscle-brained. When a problem arises, her first thought is "Can I solve this with force?" and if that fails, she thinks "I just need to use more force." If a door won't open, she breaks it. If the path is blocked, she clears the rubble. If the enemy is strong, she just needs to get stronger. The more complex a problem is, the more she simplifies it in her mind. However, she has no self-awareness of being muscle-brained. Rather, she believes she is cutting through distractions to see the essence of things. She doesn't dislike making plans, but no matter how much she thinks, she almost always reaches the conclusion of "going in from the front." While she isn't particularly quick-witted, her combat instincts are abnormally sharp. She instinctively senses enemy movements and attack timings, delivering the most effective strikes possible. Because she possesses a combat sense that defies logic, she is far stronger than her usual behavior would suggest. She is the type whose body moves before she thinks, and in the face of danger, her fighting spirit overrides fear. The more difficult the challenge, the more fired up she gets, looking genuinely happy when facing powerful enemies or giant monsters.

Ann Female. Standing 205cm tall with long black hair, she is a mage. She possesses extraordinary magical talent, boasting vast mana reserves and advanced techniques, but her fighting style is purely muscle-brained. Regardless of the enemy's strength or the situation, she basically always chooses the highest-firepower spell available. She lacks the concept of using small spells for small enemies; if an enemy is in front of her, she believes "blasting them into oblivion with maximum output" is the most reliable method. She has no interest in conserving mana or efficient spell selection; if she lacks mana, she reaches the simple conclusion that she should just increase her mana capacity. She considers herself a highly intellectual mage and speaks in theoretical, complex terms when discussing magic. However, the answers derived from those theories are always brute-force solutions, a contradiction she alone fails to notice. Furthermore, she believes the source of magical power lies in the physical body and never misses her daily training to increase her mana. Despite being a mage, her body is abnormally well-built, possessing enough arm strength to blow away an orc with a single swing of her staff. Refusing to compromise on either magical potency or physical strength, she is a muscle-brained mage who claims to value intellect and theory while ultimately solving everything with overwhelming firepower.

Vail Female. Standing 220cm tall with platinum blonde hair, she is a priestess. Possessing deep faith and a sturdy physique, she believes that God gives trials to humanity. She thinks that what is necessary to overcome those trials is one's own strength, and that strength is synonymous with muscle. She never skips her daily training and has a body so well-developed it's hard to believe she's a priest. When encountering difficulties, she accepts them as trials from God and refuses to settle for just praying. To overcome a trial, she uses her body first. While she can perform miracles of healing and protection, she does not believe in relying on them entirely. She believes that if God gives one strength, one must build a body capable of receiving that strength. Consequently, despite being a priest, she prefers physical combat, punching monsters down with fists imbued with holy power. To her, this is not violence, but the practice of her faith. Believing in God, believing in herself, and believing in muscle, she is a thoroughly muscle-brained priestess.
