Aoi Tōdō stands tall with a muscular build, tan skin, and small black eyes framed by shoulder-length black hair tied in a top-knot bun. Flyaway strands resembling flower stamens escape the knot, complementing a prominent scar tracing the left side of his face—a lasting mark from Yuki Tsukumo’s rigorous training. His modified Jujutsu High uniform features an open jacket, loose martial arts pants, and a bright blue sash. After losing his left hand to halt Mahito’s transfiguration during the Shibuya Incident, he later replaced the limb with a vibraslap. Born September 23, 2000, Aoi exhibited extraordinary physical strength early in life, drifting through monotony until meeting Yuki Tsukumo. Her provocative question—“What kind of girls do you like?”—became his signature method for evaluating others, igniting his pursuit of exhilaration and meaningful bonds. This philosophy permeates his combat style and relationships. A third-year Kyoto Jujutsu High student and Grade 1 sorcerer, Aoi merges brute force, tactical precision, and cursed energy mastery. His innate technique, Boogie Woogie, lets him swap positions of cursed energy-imbued targets via claps, enabling chaotic battle strategies. He prioritizes full-body cursed energy flow, a principle he instilled in Yuji Itadori during the Goodwill Event, catalyzing Yuji’s first Black Flash. Eccentric yet introspective, Aoi openly idolizes pop star Takada-chan, conjuring imaginary mid-fight dialogues with her. His infamous question filters out those he deems uninteresting—like Megumi Fushiguro—while shared preferences with Yuji forged an instant “brotherly” bond. Behind his boisterous exterior lies philosophical depth: he counseled Yuji to transform grief into resolve during Shibuya’s chaos and championed perseverance as a sorcerer’s core tenet. Pivotal battles chart his growth. At the Night Parade of a Hundred Demons, he annihilated five Grade 1 curses and a special grade, though rumors inflated his feat by neglecting Boogie Woogie’s role. Against Hanami, strategic Playful Cloud maneuvers and rapid swaps nearly secured triumph. In Shibuya, losing his hand and enduring Mahito’s mind games tested his resilience, yet he steadied Yuji as an anchor, reinforcing their partnership. Reappearing in the Shinjuku Showdown Arc, Aoi wielded his vibraslap prosthesis to amplify Boogie Woogie’s unpredictability. His ethos—rejecting complacency, embracing adversity-driven growth, and prioritizing lived experiences over rigid morals—stems from Yuki’s mentorship and hard-won battles. This worldview cements his role as a catalyst for allies’ evolution, notably steering Yuji from self-doubt to unshakable resolve.
