OVA
Description
Ayumi Mizuchi functions as a secondary antagonist in the source material's initial story arc. She is the middle sister of Remi and Emi Mizuchi within the Mizuchi crime family.
Before the main narrative, Ayumi collaborated in her eldest sister Remi's scheme to murder 76 classmates from Takanoha Gakuen High School. This involved attaching gas tanks beneath school buses, inducing unconsciousness in drivers and students before vehicles crashed off a cliff. The massacre enabled new student enrollment, allowing their father Gozo Mizuchi to exploit families for political and financial leverage.
At Takanoha High, Ayumi enforced control through intimidation, supported by her four bodyguards, the "Four Devas." She systematically bullied students into surrendering money, augmenting her wealth via drug trafficking and paternal donations. When Saki Asamiya arrived, Ayumi identified her as a threat and commanded the Devas to test her. After Saki intentionally lost their first clash, Ayumi dismissed her capabilities.
As Saki's influence grew, students defected from Ayumi's allegiance. Following Saki's effortless defeat of the Four Devas and public humiliation of Ayumi on campus, Ayumi swore vengeance. Her younger sister Emi denied aid, but Remi supplied a shotgun to assassinate Saki. Ayumi tracked Saki and fired, only for the weapon to explode, inflicting mortal wounds. Dying, Ayumi recognized Remi had sabotaged the gun to eliminate her and seize her hidden fortune within a woodland base.
In the manga continuity, Ayumi's aggression toward Junko Yuina diverges: she orchestrated motorcycle thugs to run over Junko's hand, crippling her artistic skills, and later enabled the murder of Junko's mother. Ayumi additionally sowed doubt in Emi about her artistic talent, indirectly fueling Emi's jealousy toward Junko. Ayumi's gang directly caused Junko's death in the manga, staging it as suicide despite venomous snake bite evidence indicating homicide.
Her demise remains consistent across media: Remi's betrayal via the rigged shotgun results in Ayumi's death. The manga further specifies that despite her greed and drug trade involvement, Ayumi demonstrated loyalty to her family and was deemed the least morally corrupt Mizuchi sister.
