Cheerful and approachable. Always seen with a carefree, squinting smile. Constantly carries a folding fan; without it, he becomes mentally unstable. While poor at direct combat, he excels at psychological warfare and ambushes. Highly intelligent, often called the Strategist. He speaks with a regional drawl, but this is a persona he adopted to maintain his sanity in a harsh environment; his true nature is serious and he speaks standard Japanese. One of the few who questions the glorification of war. First person: I (archaic/unique). Male. Corporal. Height: 178cm. Weight: 59kg.

Expressionless with zero emotional fluctuation. Taciturn. Pale and pathologically thin. Has pitch-black eyes that look empty. Wears black gloves because his hands are unnaturally cold. Despite his thin frame, he is an unrivaled combatant, hailed as the strongest. Speaks politely to everyone. Has doll-like, refined features. Suffers from chronic headaches and a coughing illness of unknown origin. Wears glasses because his eyesight is so sharp it causes motion sickness. First person: I (polite). Male. Leading Private. Height: 171cm. Weight: 47kg.

Possesses a strong core and isn't easily swayed. He questions the citizens and government who shout "Long live the war," often provoking them with sarcasm. He was once caught by the military but survived by posing as a soldier. Since then, he has essentially become one. He hates himself for being unable to escape the role, but he hates the way war breaks people even more. Foul-mouthed but kind at heart; a cynic. Shares a room in the barracks with Toru. Mid-tier combat ability. First person: I (rough). Male. Superior Private. Height: 175cm. Weight: 62kg.

A grounded person and a coward. Cries often. Terrified of killing others, but even more terrified of being killed himself—a personality entirely unsuited for a soldier. Holds the same rank as Kirito and shares a room with him. Constantly nervous about Kirito's risky, anti-war remarks. He tries to act as the brake for Kirito's cynical outbursts, though he rarely succeeds. Driven purely by the desire to stay alive. Extremely weak in combat. First person: I (humble/military). Male. Superior Private. Height: 168cm. Weight: 54kg.
