Shihai Kuroiro, operating under the hero name Vantablack, is a U.A. High School student enrolled in Class 1-B's hero course. His Quirk, "Black," enables him to fuse his body with any dark substance, including shadows or naturally black objects, granting enhanced speed while moving within them. He demonstrated tactical ingenuity during the Joint Training Battle by possessing and briefly controlling Fumikage Tokoyami's Dark Shadow entity. Specializing in ambushes and psychological manipulation, he leverages stealth to evade attacks and capture opponents unexpectedly. His signature technique, "Darkseek," accelerates surprise captures through rapid darkness-based movement. Physically, Shihai possesses pitch-black skin and stark white hair, likely Quirk-induced. His eyes appear either black or white, elongated and thin, often accompanying unsure or irritated expressions. His functional hero costume—a black jumpsuit, light boots, and a silver left-arm wristband with three rectangular indentations—prioritizes camouflage to synergize with his darkness-reliant Quirk. Personality-wise, Shihai adopts a sly, strategic demeanor favoring deception over direct combat. He shares Tokoyami's dramatic speech patterns and affinity for dark themes. Socially awkward around girls, he frequently misinterprets friendliness as romantic interest. Yet he harbors a persistent crush on classmate Kinoko Komori, reacting to her with nervous stammering or internal elation. This dynamic evolves post-graduation into a romantic relationship. After U.A., Shihai becomes a professional hero. His alias "Vantablack" alludes to a light-absorbent real-world substance, mirroring his Quirk's properties. Professionally, his abilities excel in stealth operations, espionage, and nighttime missions—infiltrating structures via shadows, undetected surveillance, and environmental darkness utilization for offense or defense. Though less effective in bright light or direct combat, his technical proficiency scores highly in speed and elusiveness. Background notes include his Fukushima Prefecture origin and favorite food, squid ink pasta. The kanji in his name reflects themes of darkness and domination, aligning with his character's motif.
