Naomi, a member of the Bottle Collectors from Oedo, has soft pastel-red hair and piercing dark violet eyes. Her silent, reserved nature is marked by a monotone voice and minimal facial expressions, conveying stoic detachment. She finds solace in biwa music from her homeland, a cultural touchstone that surfaces during key moments, such as an encounter with Emma in the Ninjala Championship arc.

During the Summer Siege on Eagle City, she joins WNA Academy peers and the oniwabanshu to combat invading space ninjas. In battle, she employs a Sushi Axe—a melee weapon forged from hardened Ninja Gum—while collaborating with her team on missions, though her personal drives and group dynamics remain undefined. No expanded backstory or arcs beyond documented events are noted.
