History YMMV / HowNotToSummonADemonLord

* SugarWiki/FunnyMoments: Diablo shows even demons can get drunk and also sees cute bunny girls as pillows.

* EarWorm: [[https://www.youtube.com/watch?v=03u-C-78N20 The Biscuit Song]].

* AudienceAlienatingPremise: The premise of this series involves a socially awkward otaku teleported into a fantasy world as his video game character (a demon king) and two girls ended up becoming his slaves by mere accident with fetishzation of slave girls will turn off a lot of people.

* EscapistCharacter: Diablo. Even more so than the usual [[StockLightNovelHero Isekai protagonists]], playing straight into the fantasies of players becoming their video game character and an extremely overpowered one at that. He also delves deeper than the usual HaremGenre wish fulfillment as Diablo has no qualms on getting intimate with them.

* MemeticMolester: Diablo. Little surprise he became one given the AudienceAlienatingPremise of a 30 something otaku who acquired two teenage girls as his slaves who he has groped on several occasions. He also shared a kiss with a technically newborn girl.

* DoesNotLikeMen: On a meta-level, the author. Through 9 volumes of the light novels, every single one of Diablo's major allies is female ([[RobotMaid or identifies as such]]); while aside from Diablo himself almost every named male character has been some kind of antagonist, one of the rare exceptions being an annoying ChivalrousPervert. It gets so bad that twists such as a certain party member turning out to be a SweetPollyOliver or the recent inheritor of the [[MasterSwordsman Swordmaster]] title turning out to be a young woman come as no surprise at all.

** [[ChurchMilitant Paladin Saddler]] of the [[Characters/HowNotToSummonADemonLordChurchOfCelestials Church of Celestials]] is a twisted sadist behind a [[FauxAffablyEvil mask of pleasantry]], Saddler butchers villages he suspects are "evil", killing them to the last man, woman and child. A [[TortureTechnician torture enthusiast]], Saddler is fond of attacking demihumans or anyone he so much as suspects of worshipping demons regardless of logic or justification, taking them and torturing them to death as a form of "purification" and justifying his beliefs under the notion that [[AGodAmI he is a god]]. When he captures Diablo's friend Rem, Saddler tries to torture her to death as well, his supposed righteousness nothing more than a mask for the twisted monster he truly is.

* EnsembleDarkhorse: Klem the [[TheDreaded Demon Lord]], who is a supporting character introduced late in Season 1. She immediately endeared fans for being an adorable TokenMiniMoe despite her fearsome reputation.

** If kidnapping Shera and trying to molest her wasn't enough for Keera to cross it, summoning the Force Hydra to incite a rampage (without any remorse for those he endangers) surely put him in irredeemable territory.
%%** Galford crosses it when he decapitates Keera.

* CompleteMonster: [[EntitledToHaveYou Keera L. Greenwood]] is the older brother of Shera and the prince of the Kingdom of Greenwood. He is known to be [[BigBrotherBully physically abusive]] towards Shera, while seeing her as nothing but a SexSlave that he rightfully owns and can use to continue their bloodline. Eventually, Shera had enough of his mistreatment and ran away, leading to him obsessively trying to recapture her and bring her back. He has a complete disregard for life, not caring how many people he endangers to achieve his goals and believes [[ItsAllAboutMe the entire world exists to please him]]. This is shown when he callously declares war over the pettiest of reasons, or when he summons the Force Hydra (a dangerous and destructive beast) even though he had no means of controlling it. He's also shown to be [[FantasticRacism incredibly racist]] to all races other than the Elves. When he finally recaptures Shera, he has her chained up and attempts to rape her while also putting her under mind control magic to make her desire to come back with him.

** Galford crosses it when he decapitates Keera.

* CounterpartComparison:
** Diablo sees a lot of comparison to [[LightNovel/{{Overlord}} Ainz / Momonga]] for many reasons. Both are gamers who are transported into the body of their [[TheAce max level]] game character, notably, both characters are spellcasters and both are of inhuman races usually perceived as evil (a demon and a lich, respectively). Both interact with the people around them [[TheRoleplayer using their character as a mask]], albeit for different reasons (Ainz does it primarily as a means to command his army of followers, Diablo, on the other hand, is so asocial that he does not know how to interact with people aside from roleplaying).
** Shera's brother, Keera, is this to [[LightNovel/SwordArtOnline Nobuyuki Sugou (particularly his ALO avatar, Oberon)]]: both of them are deprived elf like beings who are [[HateSink made to be despised]], with both having no redeeming factors whatsoever, sexually depraved individuals (though in Keera's case, [[BrotherSisterIncest he's]] [[FantasticRacism much worse]]), [[AttemptedRape tried to rape]] a female heroine (Asuna and Shera, respectively) by having them [[GoGoEnslavement chained-up and stripped]], after being defeated reveals themselves to be {{Dirty Coward}}s who completely lose their composure and [[VillainousBreakdown reduced to pathetic blubbering wrecks]], and in both times the hero (Kirito and Diablo) are [[PayEvilUntoEvil very nearly attempted to kill them]] but decide against it at the final moment. Unlike Sugou, his [[LaserGuidedKarma fate]] is [[AssholeVictim much worse]] and he [[OffWithHisHead doesn't get to live long afterwards]].
** Speaking of ''Sword Art Online'', Shera bears quite a huge resemblance to Leafa, being an elvish creature with long blonde hair, PointyEars, dresses in green, and has [[BuxomIsBetter incredibly large]] GagBoobs.

* HilariousInHindsight:
** One of Diablo's ladies is named Shera, which draws comparisons with a certain Princess of Power.
** the other is named Rem, which draws comparisons to another certain isekai character also called Rem

Overall he is a racist, SmugSnake, who practices rape and slavery, abuses his own blood, and is [[ItsAllAboutMe concerned about no one but himself]].
