Kojiro Bondo trains as a Pro Hero in U.A. High School's Class 1-B. Born on December 23 in Tokyo with blood type AB, his physique stands out at 191 cm tall, featuring yellow straw-like skin, disproportionately large hands, and a broad muscular frame. His head takes the shape of a glue-dispenser nozzle, with seven facial holes serving as conduits for his Quirk. His Quirk, Cemedine, releases a rapid-hardening adhesive from these facial apertures. He manipulates the glue's drying speed to ensnare foes or affix objects, though it disintegrates upon acid contact. His signature Glue Squall technique blankets wide zones to immobilize groups. Despite his imposing size, his combat prowess remains moderate—adept at lifting allies but average in speed and agility. Kojiro embodies a gentle giant persona, often seeming reserved or timid in crowds. He stammers during conversations, especially under pressure, and finds social exchanges challenging. Yet he operates smoothly in teams, maintaining an easygoing attitude. His hobby of assembling plastic models inspired his hero name, Plamo. He shares a functional, undefined rapport with classmate Yui Kodai. Key involvements include the U.A. Sports Festival, where he placed 25th in the obstacle race before his cavalry team’s early elimination. At the Forest Training Camp, he remained largely inactive. His most notable action occurred during the Joint Training Battle: under Setsuna Tokage’s leadership, he unleashed Glue Squall to immobilize Class 1-A students until Katsuki Bakugo shattered the strategy. Bakugo and Rikido Sato promptly defeated him. After graduating U.A., he became a Pro Hero. No documented details exist regarding his subsequent career.
