Higuchi is an obedient and humble combatant. She has no qualms about killing people as long as she is executing her orders and will sometimes be a bit too bloodthirsty, as shown when she fired at a target she was supposed to take alive. Higuchi also seems to be easily shaken by her own failures, often dwelling on the mistakes she makes mid-combat and impeding her ability further. She is extremely loyal to Akutagawa, and is actually quite kind when not on the battlefield.
