Generic premise, usual " Kicked out of the party by my comrades who were moustache twirlingly evil all this time for no good reason. And now i turn out to be the strongest afterall" . Except there is a legitimate reason at least for him to not have been strong this entire time, it's more an exploit he has the chance to use.
The art style, the dynamicism in it is fantastic tho, better action and effort in general.
My only main personal gripe is that for some reason they decided for some reason to make the MC a swordsman yet again, while there are so many more interesting ways for him to fight. Hell, bro used hand to hand damn awesomely and yet, ofcourse they gotta throw a sword in because i guess it's just the thing to do.
