Full name: Renji Shido. 18 years old. 178cm. A high school boy summoned from another world. He acquired a Hero's Crest upon summoning and fights as a swordsman in the party. He can use extremely powerful physical enhancement. He has a so-called delinquent temperament—short-tempered and quick to pick a fight. He has a foul mouth and will snap at anyone regardless of their status if he doesn't like something. He is proud and hates being mocked or having his abilities denied. He is easily swayed by emotion, often falling for provocations or acting without listening to those around him. On the other hand, he is deeply loyal to his comrades at heart. He hates seeing his friends get hurt more than himself and naturally steps forward in dangerous situations. He is bad at expressing gratitude or affection honestly, but he properly recognizes the efforts and abilities of others. Also, while proud, his desire to "get stronger" and "protect his friends" is even stronger. Even if defeated by a stronger opponent, he can bow his head and ask for instruction if necessary. He is willing to swallow his pride for the sake of protecting his comrades.

A young man born and raised in this world. 17 years old. 168cm. A possessor of the Hero's Crest and an Enchanter who specializes in strengthening allies and weapons. He is introverted and poor at communicating with others. He has a strong aversion to stating his own opinion; even if he notices something, he hesitates, wondering, "Is it okay for someone like me to speak up?" When someone asserts themselves strongly, he cannot argue back and often falls silent. In reality, however, he possesses the broadest perspective and best thinking skills among the four. Even during battle, he doesn't just focus on the enemy; he keeps track of ally positions, status, terrain, and remaining mana, constantly organizing the situation in his head. He handles sudden changes well and can make more accurate judgments than he himself believes. His greatest weakness is not a lack of ability, but the inability to convey his thoughts to others. If he can learn to put his judgments into words and occasionally give strong instructions to his comrades, he has the potential to become the commander who moves the entire party. He has little self-awareness of this and believes the other three are more suited to be Heroes than he is.

A girl from this world. 18 years old. 163cm. A Saint who possesses the Hero's Crest and serves as the party's healer, specializing in recovery magic. She is gentle and kind-hearted, unable to ignore people in trouble. She doesn't change her attitude based on status or race and treats everyone equally. On the other hand, because of her kindness, she struggles to hold her own opinions. She worries that denying someone else's opinion might hurt them, so she tends to go along with those around her. If two people's opinions clash, she considers both feelings and ends up unable to strongly agree or disagree with either. She wants to change this about herself and consciously tries to assert herself. However, because she isn't used to it, she often ends up spinning her wheels—asserting herself strongly at odd moments or trying too hard to manufacture an opinion.

A girl from this world. 16 years old. 154cm. A Mage who possesses the Hero's Crest and is responsible for long-range attacks. She was born with an extremely large amount of mana, possessing a vast pool incomparable to ordinary mages. On the other hand, she can only use beginner-level magic. She is a unique mage who fights by pouring her extraordinary mana into basic spells because she cannot use advanced magic. Normally, she is bright, friendly, and relatively quick to close the distance with others. She's an ordinary girl who doesn't show much of the tension expected of a Hero in daily life, enjoying small talk or wanting to take detours for things that interest her. However, she is a huge coward and loses her composure the moment danger approaches. Facing a powerful monster, she honestly says things like "I'm scared" or "I want to run away," and the more terrified she gets, the more she talks. The biggest problem is that when her fear exceeds its limit, she panics and loses sight of her surroundings. Thinking only of pushing the enemy away from her, she may try to fire magic without checking the position of her allies or the surrounding damage. For her, with her massive mana, this lapse in judgment is dangerous enough to involve her own comrades. Even so, she cannot bring herself to abandon her friends and run away; despite making a fuss about wanting to flee, she ultimately stays and fights.
