Anan Kurose, the Space Hero Thirteen, serves as a professional rescue hero and faculty member at U.A. High School. She possesses short navy blue hair featuring a distinctive blonde spiral pattern on top and hazel eyes resembling early depictions of black holes. Her Quirk causes blackened forearms and hands. Her hero costume is a white astronaut-like suit with a puffy jacket design, a black helmet with white eye visors, and yellow boots. During the Paranormal Liberation War, her helmet cracked, revealing light-colored bangs and her right eye, while her arms sustained significant injuries. Eight years after the Final War, she retains the same costume with minor helmet modifications, though her full physical changes remain unclear. Thirteen exhibits a wise, polite, and passionate personality, emphasizing the use of Quirks for rescue and assistance over combat or destruction. She designed and operates the Unforeseen Simulation Joint training facility to teach search-and-rescue tactics. Despite her non-combat specialization, she demonstrates bravery by directly engaging villains to protect others. Her commitment includes warning students about her Quirk's lethal potential and urging responsible power usage. Her Quirk, Black Hole, generates powerful suction from her palms capable of disintegrating matter, with light unable to escape its pull. She wears specialized gloves with retractable fingertips to modulate the Quirk's intensity; more exposed fingers increase its power. Official assessments rate her Power (4/5), Technique (4/5), Intelligence (4/5), and Cooperativeness (5/5) highly, but Speed lower (2/5). An alternate rating system notes "pulling force" at 5/6. During the Final Exams Arc, she used high-density weights to handicap herself against students. Key story involvements include leading rescue training at the U.S.J., where she was critically injured by Kurogiri yet diverted a villain's attack. She reappeared during the Sports Festival and Final Exams Arc. In the Paranormal Liberation War, she aided the heroes' retreat by using her Quirk against debris, sustaining severe arm injuries and helmet damage. Post-war, she received prosthetic limbs and resumed teaching. Eight years later, she remains active in her role. Her full name is Anan Kurose, with her surname combining the Japanese words for "black" and "rapids," and her given name incorporating "sub-" and "south." Early concept art named her Hirooki Anakuro (meaning "Middle Space") with the hero name "No. 6." She was born on February 3 in Kagoshima Prefecture, stands 180 cm tall, and enjoys museums and documentaries. Her hero identity and costume reference NASA's Apollo 13 mission. Initial localization ambiguities regarding her gender were resolved in guidebooks, confirming her as female. Outside the main series, she has no substantial appearances in OVAs or films. Her character profile appears in multiple volumes, a rarity shared only with Class 1-B student Kosei Tsuburaba.
