But thing is - since Blast rarely or never shows up at meetings, they bear an outdated, or possibly even inaccurate, knowledge of his looks. And One's narration follows what the Hero Association knows. Maybe it's completely twisted. Like - Blast never agreed to join the Hero Association, but since he was a righteous hero (and also the strongest), they assumed he would become a member and keeped an empty seat just for him, and all that based on mere sightings. It's a lot like it is with Jesus - people barely saw him, but because he was, well, God himself, millions believe in him. And someone, at some point, misjudged Saitama's age when he still had hair, and that person captured his appearance not quite exactly right.

tl;dr Blast is Saitama, because someone saw Saitama being OP when he still had hair, they misjudged his age, assumed he would want to join the Association and after that 'Blast' never showed up on a meeting.
