I haven't read it just watched the anime, at least in the anime there's no romance at all (main gang is 14-15 years old I think). Someone said the girls are the MC's harem, but there's literally been nothing of that nature up til now. I will start reading the manga now :)
Tell me is there romance or harem in this. I can't read action fantasy if it have romance. Just ruin the mechanical of the plot for me (imo)
