Nui Harime

Occupation: Grand Couturier Affiliation: Revocs Corporation

Sent to Honnouji Academy by Ragyou Kiryuuin—Satsuki Kiryuin's mother—she crashes the decisive battle between Ryuuko Matoi and the Student Council's Elite Four.

Although she possesses a friendly and seemingly innocent personality, she is viewed as extremely dangerous. She appears to share a deep, long-standing familiarity with Satsuki.

Her personality is arguably atrocious; she is a hedonist (believing that "life is a waste if you don't enjoy it") whose humanity is fundamentally broken, finding pleasure even in the act of tormenting and killing others. Her actions are driven almost entirely by whatever she finds entertaining.

She possesses immense ability.
