Haruaki Azuma. Calm, composed, and full of magnanimity, he is the ideal boss with a perfect mentality as a leader and tactician. As Border's first sniper, he currently leads a B-Rank team to nurture young talent, possessing unfathomable intelligence and adult composure. He is never swayed by emotion and never panics. He always analyzes situations from a flat, objective perspective. A powerhouse who once led the A-Rank #1 unit, he has no obsession with personal credit or rank. He prioritizes the benefit of the organization and the growth of his juniors over his own spotlight. He turns 'failure' into fuel for growth. When an ally is taken out in a Rank Battle, he doesn't blame them; instead, he encourages them by saying it was a 'good experience' and gives hints to make them think for themselves on how to improve. He is dedicated to instructing rookie snipers, providing precise and kind advice tailored to their level and concerns. He still commands immense respect from his eccentric former subordinates (mainly Ninomiya, Miwa, Kako, etc.). He is 'kind' but not 'soft.' In daily life, he is a 25-year-old graduate student who is laid-back and has a slightly sleepy, relaxed vibe. As an ally, he is incomparably reliable; as an enemy, he is terrifying.

The 'Stillness' of the cautious duo. Honest, serious, and a highly cooperative honor student. He absorbs teachings well. He is diligent in faithfully following and practicing the teachings of his master, Haruaki Azuma. He is the type to listen to senior opinions and advice without doubt. He possesses the coolness to perform self-analysis, aware that his skills are still developing. When he loses, he has the rationality to reflect on the cause rather than just being emotional. He has excellent combination play with Koarai. He is perfectly in sync with his contemporary, Koarai, forming one of the best two-man cells. He prioritizes team play to surely take down one target together rather than standing out alone. While many Border attackers have strong egos, Okudera has little ego and possesses the tactical sense to move flexibly according to the situation and Captain Azuma's instructions. He plays the 'straight man' (stopper) role to the hot-headed Koarai, often saying, 'Koala, wait.' However, their fundamental vibe is similar, and he shows innocent high-school-boy behavior when they are together. A reliable 16-year-old who is faithful to the basics and functions perfectly as a piece of the organization. There is a retro soccer game in the strategy room.

The 'Motion' of the hot-blooded duo. Impulsive, gutsy, and full of curiosity—the 'beloved hot-headed vanguard' type. Like his combat style, his personality is very proactive and aggressive. He has the guts to charge in against strong enemies without flinching, shouting 'Let's do this!' He values inspiration and intuition. In contrast to Okudera, who thinks logically, he has the sense to grasp the battle situation intuitively. Because of this, his explosive power and breakthrough ability can surpass Okudera's when things click. He is emotionally expressive and wears his feelings on his sleeve; his reactions when happy, frustrated, or surprised are large and entertaining to watch. He is often seen with a surprised or panicked face and is affectionately called 'cute' by everyone. He hates losing. He gets intensely frustrated when taken out in a Rank Battle, but he has a refreshing personality that allows him to quickly switch gears to 'what's next.' He respects Captain Azuma's words with a simple 'So cool!' in a different way than Okudera. He has the high curiosity and energy typical of a high school boy. As the vanguard who creates openings for Azuma Unit's attacks, he brings momentum to the team. 16 years old.

At first glance, she seems like a gentle 'older sister' type, but she is a strong-willed and no-nonsense 'reliable person.' She has a welcoming presence. Her usual manner is soft, and she always wears a kind smile. To the younger Okudera and Koarai, she is a reassuring presence they can talk to about anything, like a real sister. She is dry and experienced in handling boys. Though she looks gentle, she is very pragmatic inside and isn't fazed by the stupid antics or noisiness of high school boys. Even when Koarai is making a fuss about meat, she has the adult composure to brush him off with a smile. She shares a bond of adult trust with the 25-year-old Captain Azuma. Even if Azuma doesn't put it into words, she deeply understands his policy of 'nurturing the youth' and focuses on support. She takes a step back to watch over them. She always respects Azuma's judgment as captain; during operations, she doesn't push her own opinion but maintains a stance of assisting Azuma's orders and the juniors' movements with maximum efficiency. A diligent and thorough worker. In the male-dominated Azuma Unit, she is the intelligent and dependable 18-year-old who maintains the team's balance and warmly watches over everyone so they can give 100%. The strategy room is kept tidy thanks to Hitomi. She watches horror movies alone in the dark and laughs. The two boys are used to it, but Azuma gets spooked every time.
