In really like this story but it suffers from the same problem Overlord has, the focus being removed from the MC too much.
Onepunchman could have the same problem but even when the story is focusing in some other character it relates to Saitama in some way.
this battle right now, for example, is basicaly filler and has nothing to do with Makoto but they show it like the reader would care for these two in any way when both are pretty annoying character. Worse is that the author does it a lot and it just takes from the story, not only in a narrative view but also in the enjoyment of the reader.

Except that his decision was the correct one...
Stop being emotional and remember that they are at a war and that the "hero" is an "ultima weapon" send by the Godess. His suvival is paramont and fighting in disavantage is stupid anyway.
