I don't even know where to start with this series. Ichiban Ushiro no Daimaou is a novel that pretty much tries to force you to like the jerkass protagonist it has, a totally unsympathetic demon overlord who's infinitely more powerful than everyone else in the cast and who's constantly praised by all the girls despite showing no calms on killing their family if he wants to for no real reason. Hiroshi, a member of the main cast who serves as the foil to Akuto, is called "the hero of the story" by many in-universe, and for a very good reason, he's much better written and interesting than Akuto ever was, and he should have definitely been the MC if the author didn't want all girls to be sucking a jerk's dick, which is what all female characters on the series amount to. The series doesn't even know its identity, constantly changing between being dead serious about themes like the freedom of robots to having jokes about high school girls going around with a dildo on their school. The surreal metafictional elements that pop from time to time before overtaking the series completely by the last books is either a curse or a blessing depending if you like metafiction, but one thing is for sure, it wasn't replacing any plot because this series doesn't have any real story beyond "let's have our massive jerk of an MC fight Hitler wannabes so he can appear as the ultimate hero" and being borderline episodic on that matter. Even the bittersweet ending gets worse because the only likable characters are the ones who end up suffering while Akuto gets his dick suck even more, even by GOD IN PERSON! Overall, this novel had a nice premise, but its execution was just horrible and left a lot to be desired. In all honestly, unless you're an edgy 12-14 years old, this novel isn't for you.
