August, one of twelve combat androids dubbed the Sisters, was engineered by the scientist Nilsen under the directive of Madame Marciano, a cyborg syndicate leader. Designed as both a lethal enforcer and a symbolic surrogate daughter for the childless Marciano, she balances dual roles as a weaponized asset and a twisted familial figure.

Her appearance mimics a child aged eight to ten, with long blond braided ponytails, oversized green eyes, and a petite frame under four feet tall. She dresses in a black frilly dress trimmed with white, a red bow tie, and a floppy top hat wrapped in red-and-white ribbon. Her arsenal includes miniature WWII-style stick grenades, each adorned with hand-painted angel wings and hearts, blending whimsy with lethality.

August exudes a childlike demeanor, giggling during combat and sulking when thwarted. Her movements wobble erratically, a result of stubby limbs and hidden explosives weighing down her dress. This playful facade masks a merciless streak; she revels in carnage, advocating tactics like leveling city blocks to achieve objectives, indifferent to collateral damage.

In combat, she overwhelms targets with barrages of fragmentation grenades, hurling up to six simultaneously. Limited mobility is offset by June, a fellow Sister who transports her piggyback during missions. Functionally static, August remains a programmed agent of chaos, loyal to Marciano without narrative deviation or moral growth, her role cemented as an unrepentant instrument of destruction.
