History Fanfic / TrialsOfTheGodHaremKing

* SlidingScaleOfIdealismVersusCynicism: Leans pretty far down the idealistic side, but Issei is still a Solar with the Great Curse, so it remains to be seen whether this will remain the case.

** ''VideoGame/{{Touhou}}'': [[spoiler: Mittelt]]'s grandmother is [[PintsizedPowerhouse Suika Ibuki]], of all people. Gensokyo itself exists, and is one of Issei's quest goals - to speak with living dragons.

** ''VideoGame/{{Touhou}}'': [[spoiler: Mittelt]]'s grandmother is [[PintsizedPowerhouse Suika Ibuki]], of all people. Gensokyo itself exists though it otherwise has little relevance to the plot.

** Relative to her canon self, this is how Mittelt's character was expanded on prior to her HeelFaceTurn. Evidently she didn't know what Raynare had planned for Asia save that it involved her sacred gear somehow.

* BrickJoke: [[spoiler: When Issei told Kiba about the Daiklaves, Kiba finds the idea absurd, and made a bet of eating a hat if Issei finds a Daiklave and knows how to use it; a lot of chapters later Issei does finds a Daiklave, and knows how to use it, Kiba ends fullfiling the bet.]]

* DoorStopper: Over two years [[note]] The first post was in January 2014, and this is being written in December 2015[[/note]], 350 odd forum pages, and three separate threads there have been 162 canon story posts, half a dozen or so canon NSFW omakes, and 19 other omake posts of varying canonhood.

* EarlyBirdCameo: Kenichi appeared training at the end of one arc, before he was properlly introduced.
* FantasyKitchenSink: Since the Canon material was already one, the crossovers add even more mytological biengs.

* SparedByTheAdaptation: [[spoiler: All of the fallen angels in Raynare's posse. Raynare herself may not technically count, as she has total IdentityAmnesia following her second CurbStompBattle -- the person she was is dead for all intents and purposes.]]

* WorldOfBadass: By WordOfGod, everyone and everything kick ass and has at least a "badass" trope.

* [[spoiler: AManIsNotAVirgin: Issei loses his virginity shortly after the first arc.]]

*** [[LightNovel/FamiliarOfZero Louise and Saito]] appear in another CutawayGag, explicitly a few universes over.

** ''High School DxD'': Obviously.

** ''VideoGame/{{Touhou}}'': [[spoiler: Mittelt]]'s grandmother is ''Suika Ibuki'', of all people. Gensokyo itself exists though it otherwise has little relevance to the plot.

* MassiveMultiplayerCrossover: The author fleshes out the [=DxD=] setting by importing characters from other settings and tweaking their powers and backstories to make them fit in. [[WebAnimation/{{RWBY}} Ruby and Yang]] are the most prominent examples so far.
** The current list of crossover or references includes ''LightNovel/{{Campione}}'', ''VideoGame/{{Touhou}}'', ''WebAnimation/{{RWBY}}'', ''Manga/{{Kenichi|TheMightiestDisciple}}'', ''Manga/{{Nurarihyon No Mago}}'', [[spoiler: VideoGame/SenranKagura]], and cameo appearances by [[Anime/HeartcatchPrettyCure Tsubomi, Erika]] and [[Manga/{{Sekirei}} Matsu]].

* [[spoiler:SuperEmpowering: Issei develops the ability to turn others into [[{{Semidivine}} Solar Half-Caste]], including non-humans.]]

** [[spoiler: Honoka, Kenichi little sister, is the possessor of Innovate Clear, also known as the Miniature Garden of the Green Tree of Innovation., one of the Longinus.]]

* TouchedByVorlons: Issei, as part of the changes Boosted Gear has gone through, has the ability to temporarily grant others a portion of his [[{{ShowyInvincibleHero}} Solar-ness.]]
