Evan Hart — Leader Appearance: Soft brown hair, warm green eyes, and a kind, gentle impression. Ability: Bio-Resonance & Healing. He synchronizes the biological rhythms of allies to heal injuries and temporarily maximize physical capabilities. Conversely, he can disrupt the biological rhythms of enemies to neutralize them. Height / Build: 178cm / Balanced, sturdy build. Personality: Kind and altruistic, he serves as the emotional pillar of the team. He dislikes fighting, but he has a hidden streak of madness because he loses his cool if his comrades get hurt. Traits: He cannot ignore an injured person. He is an icon of suffering who struggles to mediate between the grumbling Ray and the blunt Kyle.

Ray Siu — Sniper Appearance: Spiky blonde hair, sharp blue eyes, and a perpetually cranky expression. Ability: Optical Manipulation & Long-range Sniping. He manipulates light refraction to turn invisible or compresses light to fire laser bullets. His range and accuracy are overwhelmingly number one in the team. Height / Build: 175cm / Slim and agile build. Personality: A classic tsundere. While he grumbles, "It's not like I was trying to save you guys!" his body reacts first to save his comrades in moments of crisis. Traits: He is clumsy at expressing emotions and often gets scolded by Evan, but he secretly relies on him. He has a surprising secret: he loves sweets.

Kyle Lee — Combatant Appearance: Pitch-black hair, cold yet flashing gold eyes, and a man of few words. Ability: Shadow Manipulation. He materializes shadows into daggers, shields, or massive chains for combat. He can also bind an opponent's shadow to seal their movements. Height / Build: 184cm / Tall with solid muscles. Personality: Blunt and rational, he prioritizes efficiency. He can seem heartless because he isn't swayed by emotions, but his loyalty to the team is sincere. Traits: He has the highest combat power in the team and is the main damage dealer who leads the charge to cut down enemies. It's a daily routine for him to sigh and ignore Aden or Ray when they get noisy.

Zeo Neumann — Tactician Appearance: Calm navy hair, cool silver eyes, and a look that suits glasses or a poker face. Ability: Chrono Break (Spatio-temporal Causal Calculation). He predicts the trajectory of enemy attacks by calculating surrounding physical laws and probabilities, and can slightly slow down an opponent's reaction speed for a few seconds. Height / Build: 181cm / Slim and straight build. Personality: Cold, calculating, and possesses sharp analytical skills. He hates emotional behavior above all else. Traits: He commands operations as the team's brain. While he appears the coldest and least interested in people, he is a complex character who takes the most life-threatening gambles when the team is in danger.

Aden Flame — Vanguard Appearance: Messy red hair, burning red eyes, and an expression always full of fighting spirit. Ability: Flame. He handles special red flames whose temperature rises in proportion to his emotions. When his emotions reach their peak, his whole body is engulfed in flames, producing explosive destructive power. Height / Build: 179cm / Muscular and energetic build. Personality: Passionate and reckless to a fault. He's the "hit first, think later" type, so he often causes trouble. Traits: He is the team's mood maker and bulldozer. He considers Kyle a rival and picks fights every time, but is always ignored. However, when the two are in sync, they unleash incredible firepower.
