Kurokami no Otome, also called the Girl with Black Hair, is a university student with fair skin, dark blue eyes, and black hair. She is of shorter stature and favors a yellow jacket worn over a red dress, paired with black tights and flat white shoes for her nightly excursions. She maintains a positive and forward-facing demeanor, moving fluidly from one experience to the next without hesitation. This momentum often draws others into her wake, pulling them along effortlessly. She displays a readiness to embrace new and occasionally awkward situations, radiating a confidence that makes her the center of attention in any social gathering. Her appreciation for alcohol is marked by a seemingly limitless capacity to drink without becoming intoxicated, an ability that enables her to defeat Ri Haku, an otherwise undefeated supernatural entity, in a drinking contest. Sentimentality colors her perspective, as she looks back fondly on memories. Receiving her cherished childhood book, *Ratatatam*, from Senpai brings her profound joy. Initially disinterested in romance, her outlook shifts when Senpai confesses his feelings during a play, prompting her to recognize her own attraction and desire for physical closeness—an indication of a recipromantic orientation. Over the course of a single night, she explores Kyoto’s nightlife, encounters a variety of people, learns about different types of alcohol, and takes part in events such as a sophist dance that energizes elderly partygoers. She also visits a used book market in search of *Ratatatam*, aids the God of the Used Book Market in redistributing a rare collection, and performs in a school festival play. Throughout these activities, she remains mostly unaware of Senpai’s attempts to express his affection for her. She is regarded as highly talented—described as beautiful, wealthy, intelligent, fortunate, and proficient in martial arts. Her optimism, helpful nature, and drinking ability earn her the affection of those she meets. Inner reflections reveal a poetic and contemplative side beneath her lively exterior. Her background includes an older sister who imparted numerous life lessons and philosophies, though this sister never appears on-screen. These events unfold during one night in the film adaptation, whereas the source novel spreads them across a full year.
