Mahiru Banba stands as one of the most tragically layered assassins within Myojo Academy's Black Class. The deep psychological wounds inflicted by strobe-light abuse during her childhood gave rise to two starkly contrasting personalities: the daytime 'Mahiru,' a soft-spoken, needle-wielding girl who finds solace in sewing; and the nocturnal 'Mayu,' a battle-hungry alter ego of extraordinary physical power. Her motivation for joining the assassination mission centers on eliminating Haru Ichinose and preserving her as a coveted 'relic'—a haunting obsession that mirrors the trauma buried within her past.
