Ryuko Tatsuma, professionally recognized as the Dragoon Hero Ryukyu, holds the No. 10 rank on Japan’s Hero Billboard Chart following a drop from No. 9. Her Quirk, Dragon, enables a full metamorphosis into a massive winged dragon cloaked in pale gray scales, endowing her with formidable strength, flight, razor-sharp claws, and reinforced durability. This transformation integrates her costume, which adjusts to her draconic size while preserving scaled accents and claw guards, though her boots vanish. In human form, reptilian features emerge through slit pupils, pronounced canines, and a qipao-based uniform accessorized with dragon-themed elements—a claw-studded headband and ornamental wings. Known for humility and levelheadedness, Ryuko focuses on rescue missions and candidly owns her professional setbacks, such as her rank decline and refusal to accept praise after failing to prevent a civilian’s death. Her ethics drive her actions, notably prioritizing child safety during the Shie Hassaikai operation, where she demanded Eri’s immediate rescue. As a mentor, she empowers interns Nejire Hado, Ochaco Uraraka, and Tsuyu Asui, fostering autonomy while guiding their field training. In combat, Ryuko’s resilience shines. She clashed with Rikiya Katsukame during the Shie Hassaikai raid, enduring his strength-sapping Quirk before coordinating with her trainees to incapacitate him. Later, during the Paranormal Liberation War, she aided Endeavor against Tomura Shigaraki, momentarily pinning him alongside Izuku Midoriya until overpowered. Her endurance withstood Shigaraki’s augmented strikes and shockwaves from Nejire’s attacks, underscoring her Quirk’s defensive prowess. Her agency blends Chinese architectural influences with dragon symbolism, featuring ornate columns, guardian lion statues, and serpentine motifs. The adaptive costume and claw guards, speculated to enhance protection or amplify strength, remain subjects of analysis among Quirk researchers. Trivia highlights her name’s dual “dragon” kanji (竜・龍), a preference for glittering objects reflecting draconic folklore, Okinawan heritage, and her status as Japan’s second-highest-ranked female Pro Hero.
