not too big of a fan how op main character is. way too many stories do this same thing where they establish mc to have some big disadvantage only to almost immediatly make them ridiculously overpowered and effectively ignore any weakness they may technically have. is it too much to ask for characters to have proper weaknesses.
they could even have made it so that he is actually weak in combat but his theoretical knowledge makes him still useful but no we get another op wishfulfilment mc
