History YMMV / KimiNoNaIowa

** In Chapter 26, Ayaka sees Missouri eyeing members of the wedding guestlist in a way that makes her hear Hall & Oates or Nelly Furtado in her head. [[spoiler:As in, she's a Maneater.]]

* HarsherInHindsight: Or Energy is called as such because it is the gold from Heaven, contrasting with [[VideoGame/Doom2016 Argent Energy]] being the silver from Hell. Come ''VideoGame/DoomEternal'''s release, it turns out that "Heaven" in the Doomverse... isn't.

** In Chapter 31, Bismarck says "Man, Perl One," Perl One being Hood's callsign. "[[Creator/RonPerlman Perlman]]" is also the surname for [[VideoGame/{{Halo}} another person named Hood.]]

** This fic allows shipgirls to employ MoreDakka inspired by BulletHell from ''VideoGame/{{Furi}}'', with the first onscreen depiction released in May 2017. At the end of the month, the original Chinese version of ''VideoGame/AzurLane'' went out of beta and into public release, and its main distinguishing factor from ''[=KanColle=]'' is the use of ShootEmUp gameplay mechanics.
** While still on the topic of AL, in Chapter 17, Ayaka wonders if the Japanese do modular upgrades of their shipgirls rather than everything in one go. AL's retrofit mechanics ended up requiring you to upgrade each aspect of a shipgirl individually.
** A threefer for AL: This fic deviates from most KC fic by bringing the magic aspects of shipgirls to the fore with spellcasting that comes in a wide variety of flavours, including things that wouldn't be out of place in magical girl or superhero works, though it isn't the first KC fic to go down this route [[note]]''Fanfic/AmbienceAFleetSymphony'' at least in the latter third of its currently released chapters, would depict shipgirls with a bit of a magical streak in addition to their tech abilities, which would also not be out of place in magical girl or superhero works.[[/note]]. When the AL anime came out, it had its shipgirls doing fantastic things of their own like Kaga summoning a giant fox or Enterprise riding planes.

** Ayaka went to Japan to study her Shinto graduate course in 2019. Some time after this was first mentioned, in October 2019, one of the fic's authors actually went to Japan on vacation, during which he did a Shinkai filmography pilgrimage.

** In March 2019, cut content for Chapters 19 and 20 was released, and one of the scenes included was that of Akagi using [[VideoGame/DevilMayCry Judgment Cut End.]] Roughly 2 months later, Akagi Kai Ni Bo was released in the game, and it has Akagi with a katana.

** This fic, with its American setting, was already in existence long before it was announced that Creator/JJAbrams would be helming an American LiveActionAdaptation.

* GeniusBonus: In Chapter 13, Russian Air Force CAPT Gryzlov makes a joke about abyssals needing to make sandwiches that scares Essex and Iowa.[[note]]Where do you make a sandwich? In a [[https://en.wikipedia.org/wiki/Kh-22 Kitchen.]][[/note]]

** As noted in Chapter Two WordOfGod, Mitsuha and Itomori's {{Alternate Sel|f}}ves being Ayaka and Imamura was decided in December 2016. Months later, ''[=KanColle=]'' released I-13 and I-14, whose voice actress was... Ayaka Imamura.
