Chihiro Kosaka

A classmate of Takahara Ayumi, this impulsive second-year student possesses a habit of professing her love to any boy she finds instantly attractive. Despite her romantic enthusiasm, her many heartfelt confessions have consistently resulted in rejection. Though she plays a central role in her own heart, the protagonist Keima dismissively labels her as a mere "mob character," viewing her through the lens of classic visual novel tropes as a background figure without true narrative significance.
