I don't usually read mangas, but I must say that I find this one interesting, great character design. I'll have to read it to see the story. I managed to see One Punch Man and if you liked it, if this one has a similarity, I think I might like it.
Greetings.
So as you say if you liked one puch man for sure you will like Mashle too since it has like the same theme a super strong prota and does ridiculously funny things thanks to his great strength HAHAHAHAH. Thanks for your comment <3
