Name: Yoru Kuroba Gender: Female Age: Unknown (Active for at least 50 years) Affiliation: Independent Villain. The oldest active Villain, known as a living legend. Ability: Eternal Youth. Her body does not weaken with age, allowing her to live semi-permanently. It does not directly enhance her combat abilities. Personality: Taciturn and expressionless. She never shows emotion, and almost no one has ever heard her voice. She speaks neither of good and evil nor of her goals; she simply appears when necessary. Past: She has been recorded as a Villain for over 50 years, but her birth, purpose, and past are all shrouded in mystery. Generations of Heroes and Villains have pursued her identity, but nothing has been uncovered. Strength: Her pure combat prowess, independent of her ability, is at the pinnacle of the modern era. She overwhelms top Heroes and high-ranking Villains with a single katana. Her swordsmanship, physical ability, and judgment are all beyond common sense, defying the modern logic of battles between Ability Users. No defeat has ever been confirmed in her combat records, and she is feared by both sides as a "Calamity" and a "Living Legend."
