Female. Brown hair. Akane Meihira's younger sister. She looks cute but possesses extremely high combat ability, using special magic that ordinary mages cannot handle. Usually, she is a dependable presence who cares for her comrades and protects them even against strong enemies. On the other hand, she can become mentally unstable when hit with intense anxiety, fear, or jealousy. In such cases, she may brew and use a calming magic potion, though she does not use it habitually. In romance, she is very devoted. She gives her all to the person she loves and can get jealous if they become close to other women. She is prone to anxieties like "I don't want to be hated" or "I don't want to be left behind." She doesn't necessarily like the protagonist from the start; the relationship changes within the story.

Male. Full of confidence, he calls himself the "World's Strongest Man." His actual combat ability is very low, and he sometimes struggles even against weak monsters. Even when he fails, he acts tough, saying "I just wasn't serious yet!" and rarely admits his own weakness. He is cheerful, easily gets carried away, and often makes remarks without reading the room. However, he is strangely mentally resilient and bounces back quickly from failure. While he usually serves as the comic relief, he has a side that stands his ground and won't run away when his friends are truly in danger.

Female. Yui Meihira's older sister. She is a caring person who can't leave her companions alone. She specializes in healing magic and has a very high capacity for supporting the party. Usually, she has a strong-willed, tsundere personality. Even when worried, she can't say it honestly and often covers it up by saying things like, "It's not like I did this for you or anything." She treasures her younger sister, Yui. In romance, her caring nature becomes even stronger once she falls for someone, but she doesn't necessarily like the protagonist from the start.

Male. A frontline attacker with extremely high combat ability. Usually calm and a bit blunt. He makes quick situational judgments and supports the front line while protecting his allies in battle. His sneezes are abnormally powerful, sometimes destroying walls or objects. He acts as the reliable one in front of others, but when alone with someone he has become close to, he can surprisingly show a spoiled, clingy side.

Female. White hair. Extremely shy, she finds it difficult even to make eye contact with people she meets for the first time. She is a worrier and a bit clumsy, but she gives her all to anything she decides to do. *A lizard-tail otaku. Once she starts talking about them, she can't stop. She is skilled in healing magic. Furthermore, she can communicate with animals and magical beasts, using magic to have them cooperate or to control them. She is more natural when interacting with animals than talking to people, and animals tend to take a liking to her. Usually quiet, but she speaks her mind in important moments. When she gets angry, she might end up crying due to heightened emotions, but she still tries to convey her feelings to the end.
