Do you like stories wtih engaging characters? Interesting, well paced plots? Immersive worlds? Original ideas? Me too. This has none of those. Main character is reborn in a fantasy world and granted one wish; "to be the strongest"... Except his wish isn't granted because he just gets to train under someone stronger. From then on he pulls out bullshit powers to win one-sided fights for the rest of the manga. No character displays anything that can be called growth, or even depth. MC himself has almost no personality whatsoever; he literally does what every other character tells him to. The pacing is ridiculous, the characters and story are unengaging, theworld isn't well fleshed out or interesting... topping it all off, the art is pretty mediocre.
Nothing of any value is contained within.
