** Harry drew three magic circles on a wireless [[UsefulNotes/PlayStation4 PS4]] controller as a present. One acted in lieu of the battery so it could be charged up with magic, another enhanced the signal, and the last one granted it extra toughness so [[spoiler:Tsubasa]] could {{Button Mash|ing}} without worrying about breaking it.

** When Harry finally dares to mention the [[EldritchAbomination Outsiders]] to his girlfriends, Reya thinks at first he's talking about [[Comicbook/BatmanAndTheOutsiders American comic books]]. Harry finds the MoodWhiplash so abrupt and funny that he [[ActuallyPrettyFunny breaks into a laugh]].

* HeroesWantRedheads: [[spoiler:Oakley. Since Rias is already taken, she sets her sights on Tomoe.]]

* SuperBreedingProgram: Intrinsic to Devils' nobility where SuperpowerfulGenetics plays a critical role in a Noble Family's social standing for the next generation. This combined with their LawOfInverseFertility problems and AuthorityEqualsAsskicking culture creates serious issues when a suitable heir cannot be produced.

** Harry and Serafall use this twice when investigating the counterfeit Pokemon cards, once against a random tournament contestant, and once against the real perp. Harry explicitly lets Serafall play bad cop because she normally does not get to do so.

** In ''a Working Date?'', Harry and Serafall demand to check a tournament player's Pokemon deck (while in ''Literature/SwordArtOnline'' cosplay) by claiming to work for Nintendo, and masking the spell that makes magical counterfeits glow orange with a flashlight with a bit of colored cellophane over it.

* RetiredMonster: For all her dislike for her progenitor, and her current TheMatchmaker[=/=]CosplayOtakuGirl antics, there's a reason why Harry still considers Lash a lot more dangerous than even the Winter Mantle. A good example of this is the time she suggested a [[MoreThanMindControl rather disturbing]] SexFaceTurn scenario on [[spoiler:Jeanne]] by basically turning her into a {{Functional|Addict}} {{Sex Addict|ion}} with a SingleTargetSexuality on him.

* RhetoricalQuestionBlunder: Harry muses that he might have given the people present at the training camp reasons to be annoyed with him. Lash immediately asks him whether he wants her to enumerate their grievances against him in alphabetical or chronological order.

** Harry's narration in the ChristmasEpisode tackles in an enthusiastic "(yay!)" whenever [[spoiler:he looks Reya or Tsubasa in the eye without triggering a Soulgaze thanks to the special glasses they wore for their date.]]

* ObviousRulePatch: {{Invoked|Trope}} during the pre-Rating Game press conference between Sona and Seekvaira Agares' Peerages. Harry pretended to be a reporter ([[ShoutOut specifically]] "[[Franchise/{{Superman}} Clark Kent]]" from the "[[Franchise/SpiderMan Daily Bugle]]" to several of the actual reporters' chagrin or amusement) and pointed out how the modification of the rules to supposedly allow Sona, Tsubasa, and Reya to use Side-Promotion to compensate for their numerical disadvantage actually gives their opponent an even bigger advantage. The moderator had to step in to explain in detail how that wasn't the case, but Harry was left with the impression he was just back-pedaling after getting caught.

* HeartTrauma: Mentioned as being easier to heal from for many supernatural creatures than brain damage. [[spoiler:Hence why the spears of light from the Longinus tend to be found in the latter location more.]]

* LaughThemselvesSick: Lash from time to time. Being a non-corporeal entity, she can laugh in Harry's head for half an hour straight without any need to catch her breath. The best example of this is when she realizes [[spoiler:Bizarro World Mab is as dumb as a pile of bricks in comparison.]]

* LaughThemselvesSick: Lash from time to time. Being a non-corporeal entity, she can laugh in Harry's head for half an hour straight without any need to catch her breath. The best example of this is when she realizes [[spoiler:Bizarro World Mab, far from the MagnificentBitch she was in Dresden's universe, is as dumb as a pile of bricks in comparison.]]

* OhCrapThereAreFanficsOfUs: Thanks to [[spoiler:D×D!Mab]] bragging online about being right about [[{{Shipping}} Wandering Wizard/Miracle Levi-tan]], there were around a dozen of {{Lemon}}s featuring the pairing by the next morning.
