Description
Tokaku Azuma, a 15-year-old from Nagano Prefecture’s Azuma assassin clan, inherits a lineage tracing to the Heian period. Raised by her grandmother following her mother Sorami’s death in childbirth, she endured rigorous training in lethal arts from early childhood. Her aunt Mako’s failed intervention—a plea at a family shrine to reject violence in her mother’s name—ended when her grandmother executed Mako before her eyes, scarring Tokaku with trauma that stifled her ability to kill despite her expertise.

With short blue hair, piercing blue eyes, and an androgynous build, Tokaku dons Myojo Academy’s uniform: white short-sleeved shirt, plaid tie and skirt, and tall brown boots. Her name, signifying “rabbit’s horn” (an idiom for impossibility), embodies her grandmother’s intent to mold her into an entity whose mere reputation paralyzes foes.

Cold, detached, and averse to intimacy, Tokaku enforces formal address to maintain distance—a facade shattered upon meeting Haru Ichinose, her assigned assassination target in Class Black. Defying her mission, she develops romantic feelings for Haru, abandoning her role as a clan weapon to shield her from rival assassins. This choice marks her evolution from obedient killer to self-driven protector.

Trained in knives, agility, reflexes, and sensory acuity (notably smell for threat detection), Tokaku also wields proficiency in explosives, swords, and combat. Psychological barriers from her aunt’s death initially crippled her capacity for lethal force, until a pivotal clash with Haru: stabbing her to verify if her emotions were genuine or manipulated by Haru’s pheromones. Haru’s survival, aided by a titanium rib, confirms Tokaku’s authentic love, resolving her inner conflict.

Before Myojo Academy, Tokaku thrived at Academy 17, a facility honing assassins. Her grandmother’s death severed remaining clan ties, leaving her the sole Azuma heir. Personal quirks include four-hour nightly sleep, a preference for curry, aversion to prunes, and blood type A.

Post-conflict, Tokaku stays devoted to Haru. Their bond, surviving assassination plots, matures into a mutual partnership unshackled from external control, as shown in epilogues. Her journey concludes as a testament to self-authored loyalty, transcending a legacy of violence.
