Kurokami no Otome, known as the Girl With Black Hair, has fair skin, dark blue eyes, and black hair. She is shorter in stature and wears a distinctive outfit during her nighttime adventures: a yellow jacket over a red dress, paired with black tights and white flat shoes. Her personality is eccentric, free-spirited, and relentlessly forward-facing. She moves constantly from one experience to the next without pausing to look back, pulling others into her orbit through infectious energy and pace. This approach wraps up numerous people and events in her wake. She exhibits strong confidence and optimism, naturally becoming the center of attention in social situations. An inherent curiosity and enthusiasm for life drive her to embrace new experiences, even embarrassing ones. She possesses a notable fondness for alcohol and demonstrates an extraordinary capacity for drinking without becoming inebriated. This ability enables her to win a pivotal drinking competition against the supernatural entity Ri Haku, who had never lost such a contest. Her victory clears her father's debts. Beyond this, she displays sentimental tendencies, experiencing deep happiness upon receiving a treasured childhood book titled *Ratatatam* from her Senpai. Her romantic development unfolds gradually. Initially unaware of Senpai's persistent affections, she shows little interest in romance. Her perspective shifts during a guerrilla theatre production where she plays the lead role. Senpai's impulsive confession and embrace awaken reciprocal feelings, leading her to identify as recipromantic. This sparks newfound romantic attraction and a desire for physical closeness, like hugging her carp-shaped backpack. She consistently demonstrates a willingness to help others. She aids the God of the Used Book Market by redistributing Ri Haku's rare book collection into circulation, making literature more accessible. Later, when a mysterious cold spreads through the city, her immunity allows her to nurse the sick back to health, including Senpai and companions from her escapades, highlighting her nurturing side and sense of responsibility. A defining philosophy termed the "friendly punch" guides her navigation of life's challenges with resilience, kindness, and grace. She uses this outlook to deflect unwanted advances while maintaining composure. She views life through a lens of serendipity, believing in the interconnectedness of people and experiences—contrasting with Senpai's calculated attempts to manufacture fateful encounters. Her journey reinforces her conviction that everything unfolds through meaningful connections. Her immunity to the cold epidemic symbolizes her resilient, unifying role. The event culminates in Senpai giving her the *Ratatatam* book and suggesting a future outing to a used bookstore, which she enthusiastically accepts, signaling their blossoming relationship.
