Ibara Shiozaki trains as a Pro Hero in U.A. High's Class 1-B, wielding the Vines Quirk: thorn-covered green vines sprout from her head as hair. These versatile vines extend, detach, and regenerate with sunlight and water, aiding combat, defense, and rescue operations. Her area-control tactics immobilize foes but struggle against swift close-range fighters. Medium height with dark green eyes, Ibara drapes waist-length vine hair across her forehead in a cross-like symbol. Her initial hero costume—a plain white robe and knee-high boots—later evolves into a strapless white dress, vines tied in a ponytail, and ornate red earrings. Modest and deeply religious, Ibara invokes divine judgment, heaven, and hell while championing fairness. She openly condemns deception, rejecting Neito Monoma’s sabotage plan during the U.A. Sports Festival and chastising Jurota Shishida for using her as a "sinful" decoy. She corrected Present Mic’s "assassin" label, insisting her goal is to "spread good." Though pacifistic, she harshly judges unethical conduct, including Class 1-A. Her journey begins with fourth place in the U.A. Entrance Exam. At the Sports Festival, she placed fourth in the obstacle race and joined Tetsutetsu Tetsutetsu’s cavalry team. Disqualified but granted a second chance by Itsuka Kendo, she defeated Denki Kaminari using "Crucifixion" to insulate his electricity before losing to Tenya Ida’s speed. Mustard’s gas incapacitated her at the Forest Training Camp until Tetsutetsu rescued her. During the Joint Training Battle, her team faced Class 1-A and Hitoshi Shinso. After capturing Denki and Eijiro Kirishima, Hitoshi brainwashed her, causing defeat—a moral failure she lamented. The Lurkers (Edgeshot, Kamui Woods, Mt. Lady) recruited her for an internship honing team coordination, vital during *World Heroes' Mission* where she aided Egypt’s task force against Humarise and prayed for Izuku Midoriya’s safety amid false accusations. In the Paranormal Liberation War, she helped sedate Gigantomachia but regretted the ambush as dishonorable. Graduating as a Pro Hero, her combat stats formalize: technique (5/5), power/intelligence/cooperativeness (3/5). Named techniques include "Via Dolorosa" (area traps), "Crucifixion" (immobilization), and "Faith’s Shield" (defense).
