I haven’t gotten very far in this manga, only up to the point where the guy steps on the mc, but isn't this a total ripoff of “Isekai Walking”? The mc even has the same name, and the start is pretty much the same as well. It seems pretty unoriginal to me; I would recommend reading Isekai Walking instead. Yes, the idea is cliche, but it is executed much better than this. Edit: After reading the chapter, it doesn’t seem to be all that bad, but if you prefer manga that's more casual and has a slower pace, then you’re better off with Isekai Walking. However, if you like fast-paced action manga and fancy a MC that gets overpowered quickly, then this is for you.
