Honestly, Mae no Mura has done the "Misunderstand the OPMC as weak" a whole lot better. At least in that story, the MC's powers were acknowledged by some characters, but misunderstood by others. This story goes from either 100% misunderstanding, to 100% worshiping the MC.
Either way, same nice fantasy crap to flip through as a buffer. Don't even need to read it.
Seeing how the author makes this one too (The Hero Who Returned Remains the Strongest in the Modern World
) I guess misunderstanding is the only thing the author knows how to do?
sure you could possibly make the "believe hes weak but hes actually really strong" to be interesting for a few chapters but... this is just trash at this point. so bland story and its just repeating the exact same thing over and over "oh no im too weak and everyone hates me".....
