Description
Ouka Ootori (鳳 桜花) is the primary female protagonist of the story and a first-year student at the Anti-Magic Academy, where she is assigned to the 35th Test Platoon, a unit known derisively as the Small-Fry Platoon. Before coming to the academy, she was a member of the Dullahan, the Inquisition's elite special unit EXE, and the youngest person ever to become an Inquisitor. Her career came to an abrupt end when she killed a witch in violation of regulations, an act of excessive force that led to her demotion and reassignment. Her placement in the 35th Platoon was secretly arranged by the academy's chairman, who is also her adoptive father.

Ouka's background is defined by tragedy. Her adoptive family was killed by a witch when she was young, and in the incident she was possessed and forced to kill her adoptive parents and younger sister. This trauma is the root of her intense hatred of witches and magic, and it drove her to devote her entire life to hunting them. Her ruthlessness in the field earned her the nickname Calamity, a reference to the way she would shoot down offenders without mercy. Her efficiency and dedication made her a prodigy who excelled in every form of combat and possessed the skill to operate entirely alone.

In personality, Ouka is rigid, strong-willed, and military in manner. She has a powerful sense of justice and an intolerance for wrongdoing, which makes her inflexible in her methods and slow to accept compromise. Years of working solo left her socially awkward and poor at reading situations, and she tends to be blunt and confrontational. She has a short temper and can be physically violent when provoked, especially in response to what she sees as disrespect or immorality, and she initially clashes with the other members of her platoon. Despite her ferocity toward witches, she has a fear of ghosts, and her simple tastes include milk and anpan.

Her motivation throughout the early part of the story is vengeance. She hates magic itself and believes that wiping out witches is the only correct course, which brings her into direct conflict with Mari Nikaido, a witch who believes magic exists to make people happy. Ouka despises Mari at first, both for being a witch and for her personality, and the two exchange open hostility. She also initially holds the 35th Platoon in contempt, dismissing them as incompetent and preferring to act alone. Her relationship with the platoon's captain, Takeru Kusanagi, is central to her development; he repeatedly tries to earn her trust and vows to become her trusted comrade, even though she often reacts to him with violence, particularly over accidental perversion.

Over the course of the series, Ouka grows significantly. She gradually learns to control her emotions and to cooperate with her teammates, coming to trust the platoon she once looked down on. Her views on magic soften as she comes to understand that magic itself is not evil and that responsibility lies with the people who misuse it. She also lets go of her desire for revenge: when she has the chance to kill the criminal known as Laugh Maker, she chooses instead to arrest her, rejecting the cycle of vengeance that once consumed her. She also warms to Mari, accepting her as a witch ally and abandoning her earlier mockery.

Ouka is a combat prodigy with exceptional skill in nearly every type of combat, including handguns, assault rifles, and shotguns. Her time as a Dullahan gave her advanced tactical insight and the ability to operate effectively on her own. She is connected to the Malleus Maleficarum IV, Vlad III, a pair of twin pistols from the Relic Eater series of magical weapons, and she is contracted to Vlad, which allows her to use it in battle.
