Current Version: Akari Nakayama is a 24-year-old officer known for her deep, authoritarian voice. She is a no-nonsense individual, highly dedicated to her job, and commands respect and attention with her firm and unwavering tone.

Flashback Version: In a flashback scene, Akari is younger, undergoing military training. Her voice remains deep but lacks the confidence and stability it has in the present. This version of Akari shows glimpses of the strong officer she will become, but her tone is more uncertain and reveals the challenges she faces as she grows into her role.
