Unwavering devotion to her superior

Nio Hashiri blends seamlessly into Black Class under the guise of a bubbly, gossip-loving schoolgirl—a carefully constructed persona that conceals her true identity as Nio Kuzunoha, heiress to the ancient Kuzunoha assassination lineage. Her body is adorned with phoenix tattoos symbolizing her clan's legacy. Wielding authority over life and death as the class Arbiter, she commands mastery over illusion arts and lethal techniques, all while maintaining fanatical loyalty to the chairman. She stands as the crucial link between the shadowy power brokers and the assassins who carry out their will.
