You all know the thoroughly disproven theory that Blast is a future version of Saitama. But what if instead Saitama really was Blast? Basically he's older and does all the stuff we know Blast did, except the Cube and God shit. No idea whats up with that so I'm not touching it.

Can friendly monsters make an environment for coexistence with heroes? Can a man regain lost emotions? Can a girl finally get two years of torment lifted? Shall we find out? This is a bit of my own form of guilty pleasure that I have been working on off and on for some time. How long with this fiction go? I have no idea!

Just when Saitama was doled out enough points to become S Rank he wakes up in another world full of monsters, magic, and kings. How will he adjust in this new world?

What would happen if Saitama decided to not kill all the opponents he faced and instead tried talking them out of being the bad guys.

"-Disculpa las molestias pero, ¿tendrías tiempo para escuchar hablar sobre el gran héroe Saitama? -Es la sexta... no, la octava vez que él toca la puerta tratando de convencerlo. -Soy el discípulo de Saitama, el primero y único. -Dice Genos. -Pero, comparado con él, no soy nada."
