Then suddenly Saitama woke up

Bruh.

Great fanfic with good writing and an intresting story.
Keep up the good work.
I mean
This is a oneshot but whatever.

(pulls out tissue box)
(logs in...meh too lazy)
(starts clicking on the Fav button at a speed faster than Sonic and Flash)
And that, folks, is how the anime OP was made.

Holy... This had to be one of THE BEST one-shots ever. REALLY good writing my friend! Please continue!

Nice cool story

I wonder where the room, wall, and just about everyone else came from. Also, it was pointless to say "faster than the moon moving at light-speed." You may as well have just said light-speed, because, you know IT'S LIGHT-SPEED. Anyway, that seemed pretty cool. Not sure why he needed to bring back the dead monsters since I highly doubt Saitama will remember any other than some of the ones from his early days (like that blue-frog that stole DVDs) and Boros. Great story, and while you did leave it on a cliffhanger, this was extremely well made!
Blast is real though. That has been confirmed, as he was the one who saved Tatsumaki and inspired her to be a hero.
