OVA
Description
Monaka Noguchi embodies a dual existence, outwardly projecting the image of a timid, clumsy high school student while covertly executing duties as the vigilante assassin dubbed "Angel of Death." By day, she performs part-time at Tokyo's Apollo 11 maid café, meticulously sustaining a façade of vulnerability and social awkwardness to deflect harassment through quiet restraint. This persona starkly opposes her nocturnal operations, where she dispatches criminals with clinical precision, marking each scene with a signature white feather. Her vigilantism continues the legacy of a vanished predecessor, though the circumstances of her recruitment stay concealed.
Familial estrangement defines her past. Her father, astronaut Orudo Noguchi, communicates from the International Space Station in emotionally distant exchanges, gifting her a bracelet forged from Martian rocks—a token of their strained yet caring bond. Residing with her cousin Azuki in unexplored domesticity, Monaka's isolation deepens with her mother's noted absence.
Her pivotal character arc ignites when Orudo suffers grotesque mutation after solar radiation interacts with experimental space food, transforming him into a near-invulnerable, murderous entity. Tasked to eliminate the escaped creature unaware of its identity, Monaka confronts it. The monster recognizes her via the Martian bracelet and hesitates; she seizes this opening to exploit its oral weakness and strike the killing blow. Discovering the target was her mutated father forces a reckoning with their fractured relationship. The narrative closes ambiguously upon her second encounter with the regenerated monster.
Interpersonal ties further shape her: she shares a protective, quasi-maternal bond with café coworker Manatsu Mukai, a single mother who shelters her from harassment and obliquely cautions against dual-life perils. Simultaneously, a charged dynamic unfolds with police investigator Rin Gaga, who traces her vigilantism. After uncovering her underage employment, he bargains for a date in exchange for silence, establishing a tentative, uneasy rapport.
