I still find it amusing how people kept thinking Blast was Saitama. Like, fools, How old was Tatsumaki when she was rescued? She was in her teens, Blast was probably in his mid to late 20's. Time-skip to current, Maki's mid 20's now. So we get 10 years. How old would Saitama been then? 15. Give it a rest and look at the time line.
