Tadakuni no Imouto

Tadakuni no Imouto is known for her volatile and unpredictable temperament. She frequently resorts to physical outbursts, often striking Tadakuni, Hidenori, and Yoshitake whenever they cross her boundaries. Her aggression is most notably triggered by the boys meddling in her private affairs, such as stealing her underwear, making her a feared presence during the group's antics.
