Please don't let this die. It is interesting as hell even if the setting for the people and placed is a bit too normal. Just please don't let this die.
Though there's also the thing with the series name and main visuals including a character that barely appears or does anything in the story beyond chapter one, which feels interesting as a plot twist but certainly isn't as compelling as them actually having to fight together, doubly so when the Demon Lord was actually similarly inexperienced as our protagonist in how to fight.
But that still doesn't mean everything else that's come isn't good and interesting on its own.
