Hiryu Rin, known as the Pro Hero Dragon Shroud, is a Chinese student who transferred to Japan in elementary school, becoming fluent in Japanese and culturally adapted. He possesses lightly tanned skin, black hair in a shoulder-length braid, and distinctive reptilian-shaped eyes with miniature irises. His hero costume blends traditional Chinese Jiangshi elements: a high-collared bodysuit (originally black with yellow clouds, later blue), knee-high boots, yellow gauntlets, and a talisman-like visor inscribed with characters meaning "protection of life." Collagen and calcium supplements on his belt support his Quirk. Academically diligent and strategically minded, he exhibits a serious, focused demeanor in combat and training. He is highly observant, noting environmental details or opponent behaviors, and values teamwork, coordinating with others during the U.A. Sports Festival obstacle race to clear debris. He feels responsibility toward classmates, especially fellow international student Pony Tsunotori, sharing a bond as non-native students. His Quirk, Scales, generates hard, reptilian scales from his skin for full-body armor or projectiles. Techniques enhance his combat: Leafy Scales fires scales rapidly via gauntlet-mounted launchers; Scales of Wrath protrudes scales as spikes for close offense; Inner Carapace encases his entire body in scale armor for maximum defense. His Scale Gauntlets store and fire scales like a Gatling gun, complemented by Scale Boots. The armor's main weakness is vulnerability to sufficient blunt force, demonstrated when Tsuyu Asui shattered it during joint training. His story begins in U.A. High School's Class 1-B. During the U.A. Sports Festival, he placed 32nd in the obstacle race and partnered with Jurota Shishida in the cavalry battle; their team lost after Shoto Todoroki froze them. He disagreed with Neito Monoma’s strategy to underperform to avoid targeting, prioritizing earnest competition. In the Forest Training Camp Arc, he undertook training to expand his Quirk's limits but was incapacitated by Mustard’s gas during the villain attack. Significant development occurred in the Joint Training Arc against Class 1-A’s Team 1 (including Denki Kaminari and Tsuyu Asui). He detected Tsuyu’s camouflage and destroyed one of Denki’s trackers on Jurota, but Hitoshi Shinso’s voice-mimicking Quirk tricked Ibara Shiozaki into releasing vines, enabling Tsuyu to defeat Hiryu and Jurota. This loss highlighted communication flaws, though his tactical analysis was noted. Later, he undertook work studies with Yosetsu Awase. By the Final War Arc, he graduated as a Pro Hero. He joined the mass deployment via Kurogiri’s Warp Gate to reinforce allies against All For One at Mount Fuji, declaring solidarity. His birthday is July 14, zodiac sign Cancer, and blood type A. His hero name "Dragon Shroud" (龍帷子) reflects his Chinese heritage and scale abilities. Stat-wise, he ranks highly in intelligence ("Wits") and cultural adaptability ("Chinese Factor").
