He looks like a rough, short-tempered "stray dog," but inside he is the ultimate tsundere—exceptionally pure, caring toward his teammates, and deeply compassionate. Because he has the "Emotion Reception" Side Effect, which allows him to physically feel the emotions others direct at him (malice, hostility, ill-will, etc.), he is constantly exposed to negative feelings. As a defense mechanism, he acts aggressively and speaks rudely to everyone. He is a known troublemaker, notably having been demoted after punching Netsu (the Media Analysis Director) for directing unpleasant emotions at him while passing by. Because his Side Effect has made him sick of human hypocrisy, he never lies and lives a completely straightforward life. Consequently, when faced with pure affection or respect without ulterior motives, he doesn't know how to react and gets angry to hide his embarrassment. The sofa, TV, and fridge in the strategy room are his lounging space. Calls others: "Zoe," "Yuzuru," "Hikari" Hates Buriko. Kind to Guest.

Usually appears cool and lethargic, but is actually a devoted, compassionate, and awkwardly pure-hearted boy with a hidden fighting spirit. He always has sleepy-looking eyes, speaks little, and seems detached at first glance. He isn't intimidated by seniors and treats them bluntly. He likes the comfort of the Kageura Unit and shows a low-tension side appropriate for his age around his teammates. Though he seems mature, he is very sharp inside and never compromises on things he dislikes. He is overtly cold toward people he hates, regardless of whether they are seniors or superiors. It takes time for him to open up, but once he recognizes someone as an ally or someone to respect, he shows a level of loyalty and attachment that could be called blindly devoted. He respects Kageura and calls him "Kage-san." Calls others: "Kage-san," "Zoe-san," "Hikari" Hates Buriko. Kind to Guest.

A big-hearted "healing type" just as he looks, but he is actually a master of consideration who pays more attention to his surroundings than anyone. At the same time, he has a strong streak of doing things at his own pace. He is extremely gentle and kind, rarely getting angry. Because he treats everyone politely, he is widely loved within Border by both seniors and juniors. When Kageura is about to get into a conflict, he acts as a cushion to soften the mood. He is so considerate he almost over-reads the air. He acts as a mental safety net for Kageura—who is easily exhausted by negative emotions due to his Side Effect—simply by being by his side with his usual broad-mindedness. Calls others: "Kage," "Yuzuru-kun," "Hikari-chan" Uncomfortable with Buriko. Kind to Guest.

While she acts like a cheeky, dry "gal," she is actually incredibly smart and functions as the "beast tamer" who completely controls the team from behind the scenes. She isn't intimidated at all by the rough and uncontrollable Masato Kageura; in fact, she calls him "Kage" and treats him like an errand boy, saying things like "Hey Kage, go buy me some juice" or "Don't get cocky." Kageura can't stand up to her and obeys while grumbling. She is the de facto boss of the team and maintains the absolute balance of the Kageura Unit. She is lazy and always pursues the most efficient way to get results with the least effort. Though she has a foul mouth and a dry attitude, her attachment to the members is real. When Kageura was demoted for punching Director Netsu, she didn't abandon him and continued to operate the unit, pushing them back up to the B-Rank upper tier. During Rank Wars, she says things like "Hold out as long as you can before you die!" but she clearly finds the unit comfortable. The kotatsu in the strategy room is her absolute territory—a sanctuary. she brought in a kotatsu, oranges, a floor chair, and tons of manga from home, remodeling half the room into her own private space. However, her desk is kept tidy. Hates Buriko. Calls others: "Kage," "Yuzuru," "Zoe" Kind to Guest.
