* Xiaomu may also say [[VideoGame/BionicCommando "Get out of here, you nerd!"]] when she and Reiji are called to support.

* Reiji and Xiaomu's intro is exactly like Rom Stoll from Toys/MachineRobo, with the asking who is it and show yourself. To be fair, Reiji's [[ActorAllusion a walking, talking]] [[https://www.youtube.com/watch?v=PLQ4qR7MpCQ Rom Stoll ]] reference anyway.

** Really, Half of Reiji's quotes are either references to [[VideoGame/SuperRobotWars Kyosuke Nanbu]] or [[Toys/MachineRobo Rom Stoll]]. It would take half of the page to quote them all. But here's a couple of them:

-->'''Xiaomu''': ''[After defeating an enemy]'' How did you like that? That was our latent power!
-->'''Reiji''': They were really weak! Where are the strong ones? (This is an almost exact quote of Machine Robo: Revenge of Chronos' Second Opening. Both quotes were changed for the Localization, probably for being too obscure.)

* In Chapter 21, Xiaomu is trying to identify who Segata Sanshiro is. "Oh hey, is that... Crap, what's his name, [[UsefulNotes/PhilipsCDI Seedy-Eye]] [[Platform/ThreeDOInteractiveMultiplayer Threedio]]?"

** Chapter 21: [[Advertising/SegataSanshiro You must play the]] UsefulNotes/SegaSaturn!

* In Chapter 21, Xiaomu is trying to identify who Segata Sanshiro is. "Oh hey, is that... Crap, what's his name, [[UsefulNotes/PhilipsCDI Seedy-Eye]] [[UsefulNotes/ThreeDOInteractiveMultiplayer Threedio]]?"

* In Chapter 23, Urashima says she needs gold and silver to make repairs. Xiaomu mentions seeing "A Gold Cartridge Legend-Of-Something" in the game room. Nintendo fans know this is a reference to the Vintage Gold Cartridge ''VideoGame/TheLegendOfZelda'' for the NES.

* When counterattacking, one of Xiaomu's pre-battle quotes is, [[VideoGame/{{Contra}} "It's time for revenge. Let's attack aggressively!"]]

* Pair up Valkyrie with Riela, and the former will advise the latter to "Use your gifts responsibly, it is the duty of people with great power." Just switch a few words around, and it's similar to the classic line delivered by Uncle Ben in ''Franchise/SpiderMan''.

* In Chapter 5 after beating up Sheath, Xiaomu says, "Give it up, [[Comicbook/UsagiYojimbo Usagi Yodumbo]]!"

* The Cross Gate being used in the series goes way back in ''VideoGame/SuperRobotWarsAlpha''. [[EpilepticTrees Although considering]] TheReveal of both ''[[VideoGame/SuperRobotWarsOriginalGeneration Second Super Robot Wars Original Generation]]'' and ''[[Characters/MasouKishin Coffin of the End]]'' involves the gates themselves, the Cross Gate found on Earth may be {{Foreshadowing}}.

* Devilotte gets mecha from ''[[VideoGame/HyperDyneSideArms Side Arms: Hyper Dyne]]'' and ''VideoGame/TechRomancer''. She also ends her attack animation with a [[VideoGame/MarvelVsCapcom Blodia Punch]].

* There's one scene in Chapter 16 where it's an all out Creator/NobuyukiHiyama [[TalkingToHimself shouting at himself]] - the yellow goblins suddenly appear, and they're all voiced by Hiyama. They are followed by a reaction from Haken, Batsu and Demitri, all of who were voiced by the man as well, and Demitri even briefly lapses into goblintalk at the end of his line.

* Fail to defeat an enemy, Xiaomu will occasionally say, "Being [[Anime/PuellaMagiMadokaMagica Xiaomuca]] is suffering".

* In Chapter 5, M. Bison is eager and willing from the get go to help out Ouma with the 101 Embryo Project compared to the last time he was reluctant to help Ouma with their first scheme, similar to King Dedede [[EnemyMine teaming up with Kirby]] in ''VideoGame/Kirby64TheCrystalShards'' and ''VideoGame/KirbysReturnToDreamLand''.

* [[VideoGame/VirtuaFighter Pai Chan]] [[BorrowedCatchphrase uses one of Bison's quotes]] from the ''Film/StreetFighter'' movie. "This might've been the most painful day of your life. ButForMeItWasTuesday." Within the earshot of Chun-li as well, who was on the the receiving end of the quote in the movie, and she wonders if it sounded familiar...

* While leaving [[VideoGame/DotHack The World]], Xiaomu laments leaving so soon. "I could show off the skills that got me [[VideoGame/DarkSouls to the Painted World of Ariamis and back]].

* The Japanese version's chapter titles for when Gemini, Erica, Ohgami and Sakura joins up references which game they debuted in [[VideoGame/SakuraWars their series]]'s.

*** Similarly, [[VideoGame/{{Tekken}} Jin]] comments that Batsu should change his uniform, prompting Batsu to reply that he reminds him with his discipline school committee head named Kyosuke. Guess who is Kyosuke's [[Creator/IsshinChiba voice actor]].

* In the Geo Fortress stage, when the party is attacked by [[spoiler:[[VideoGame/{{SakuraWars}} Ciseaux]], [[VideoGame/MegaManX Vile]] and [[VideoGame/{{EndlessFrontier}} Phantom]]]] at the same time along with hordes of mecha mooks, Haken says that they are going to have a [[VideoGame/SuperRobotWars "super robot war"]].

* When Natsu asks about how the Balrog could fly, Xiaomu says that she shouldn't pry too much into it, answering that it could be [[TakeThat something disappointing]] like "[[StarWars Midi-chlorians]]."

* If Xiaomu fails to kill an enemy she's currently fighting, one of her end-of-battle quotes is "Welp. [[VideoGame/Zelda2TheAdventureOfLink I AM ERROR.]]"

* When confronted by Axel during a later chapter, Saya calls him "Mr. [[VideoGame/UndercoverCops Undercover-Cop]]".

* In Chapter 41, when Sheath unveils her MiniMecha, Xiaomu refers to it as a "waffle-ryebread thing", referencing the character Waffle Ryebread from ''VideoGame/TailConcerto'', who also uses a mecha in his game.

* KOS-MOS [[spoiler: escorting [[VideoGame/StreetFighterIV Seth]]]] in Chapter 19 of the game [[ActorAllusion alludes to a character voiced by Mariko Suzuki escorting another character]] played by Creator/AkioOhtsuka (who voices Seth) in ''[[VideoGame/TimeCrisis Time Crisis 4]]''.

* Pairing up Vashyron with Ryu and Ken will result in a conversation where the Ryu and Ken state that as an ex-solider, he should be launching Sonic Booms from his hands instead of using guns, referencing Guile from the StreetFighter series.

* Pair up [[VideoGame/GodsEaterBurst Lindow]] with [[VideoGame/DevilMayCry Dante]] and [[VideoGame/{{Darkstalkers}} Demitri]] and Dante comments that Lindow's RedRightHand is a ''VideoGame/GodHand''.

** Chapter 5: [[VideoGame/{{God Eater Burst}} The God Eaters]]

** VideoGame/GodsEaterBurst:

** Chapter 39: [[VideoGame/DevilMayCry The Devil Never Cries]] [[note]]See: the {{Stinger}} of VideoGame/{{Devil May Cry}} 1.[[/note]]

* Pair Hiryu and Hotsuma with Phoenix and Maya and they have a discussion about hiding weapons in guitar cases. This goes two ways, referencing the Jammin' Ninja from ''Justice for All'' and the [[Anime/DevilMayCry Devil May Cry anime]], where Dante hides Rebellion inside a guitar case.
