Hanta Sero, hero name Cellophane, hails from Tokyo. His Quirk, Tape, enables him to shoot adhesive cellophane-like strips from dispensers in his elbows. His name incorporates kanji: "Sero" (瀬呂, rapids and spine) and "Hanta" (範太, example and thick), forming a pun on "serohan tēpu" (cellophane tape). Physically, Hanta stands 177 cm (5'9¾") with a lean build, spiky black hair, and almond-shaped black eyes. His grin is dominated by notably large, straight teeth, and multiple characters describe his face as plain. Cylindrical tape-dispenser mechanisms are embedded in his elbows. His initial hero costume consists of a black bodysuit with white accents, yellow shoulder pads resembling tape dispensers, a yellow helmet with a black visor, and white boots with yellow trim. Eight years after the Final War arc, he appears taller and slightly more muscular, sports a thin beard, and wears an updated costume featuring a redesigned helmet and black wrist straps. Hanta possesses a sociable and humorous personality. He frequently engages in jokes and lighthearted teasing with Class 1-A classmates, including volatile individuals like Katsuki Bakugo. He often calls out irrational behavior but demonstrates loyalty and bravery in crises. Though occasionally tactless—such as comparing Momo Yaoyorozu’s Quirk to excretion, requiring an apology—he maintains strong camaraderie. He shows determination against stronger opponents, exemplified by his Sports Festival match against Shoto Todoroki where he acknowledged low odds but fought regardless. Hanta exhibits interest in romance, reacting intensely to gossip about female classmates during the Provisional License Exam and sharing rumors with peers like Denki Kaminari and Minoru Mineta. His Tape Quirk allows him to shoot, retract, and manipulate durable adhesive strips. Applications include restraining foes, creating barricades, swinging across terrain, and setting traps. Overuse causes skin dehydration. His training focuses on increasing tape volume, strength, and firing speed. Key techniques are Barricade Tape (deploying tape to shield allies) and Tape Shot: Trident (launching objects as projectiles using multiple tape strands). He excels in long-range combat and team coordination, such as combining his tape with Ochaco Uraraka’s Zero Gravity to create floating traps or exploiting Setsuna Tokage’s Quirk weakness during the Joint Training Battle. He demonstrates above-average strength for maneuvering via tape and carrying others. Official stats note high cooperativeness (5/5) and technique (4/5 B or 5/6 A+), while his academic ranking is 17th in Class 1-A. Hanta participates in key battles: the U.S.J. Incident (helping subdue Kurogiri alongside Rikido Sato); the U.A. Sports Festival (reaching the top 16 before losing to Todoroki); the Final Exams (passing the practical with Mineta against Midnight after an initial failure due to her sleep Quirk); the Provisional License Exam (collaborating with Midoriya and Uraraka to defeat "Camie"); the Joint Training Battle (devising a strategy using Bakugo’s grenade to defeat Setsuna Tokage); and the Paranormal Liberation War (assisting in sedating Gigantomachia). His development includes interning with the Lurkers (Edgeshot, Kamui Woods, Mt. Lady) to refine team tactics and overcoming self-doubt through persistence. He graduates U.A. and achieves the rank of No. 36 Pro Hero by the series' conclusion.
