Touya manifested a fire quirk, his flames being able to produce a lot more heat compared to his father's Hellflame quirk. Unfortunately, however, his own body wasn't made for the fire of his quirk, and he was prone to being burned by his own fire. Enji keeps on telling him to stop hurting himself, but Touya is so determined to prove himself and surpass All Might that he practices anyway. His flames are so strong that they can become blue, and as he grows his 'bluefire' quirk only gets stronger.
