History Manga / KuroganePukapukaTai

* CharClone: One chapter has the crew of the Unebi rescuing an army pilot named Sha "[[RedBaron the Red Comet]]" who comes complete with red fighter plane and mask.

** In chapter 15 there's an intro based on ''LightNovel/MariaWatchesOverUs'' in the light novel written by [[spoiler:Chiga]] and published by Murikami.

* BareYourMidriff: The new outfits designed for Kurushima and Nojima for the fashion show.

* IAteWhat: After the Unebi helps the Italian submarine Michelangelo Buonarroti repair their engine, her captain repays the Unebi by serving them Spaghetti with Fresh Mushrooms. However, Kuki and the rest of the crew gets sick when they learn [[spoiler:the Italians grew the mushrooms in their submarine using their damp panties]].

* NamesTheSame: Obama obviously with the [[UsefulNotes/BarackObama President of the US]].

** The ''Unebi'' is completely fictional, though with a plausible backstory except for the claim of it being modified on the slips from a commercial vessel; its appearance is all warship. It is a shortish cruiser that mounts two turrets each mounting a pair of 30cm (12") guns; these were taken from the scrapped battleship [[http://en.wikipedia.org/wiki/Japanese_battleship_Settsu ''Settsu'']], making the ''Unebi'' a small pocket battleship, similar in conception to the German ''Deutschland'' (''Graf Spee'') type although significantly smaller. Such a ship ''is'' mentioned in US intelligence reports on Japanese ship builds of the period, explicitly as a Japanese take on the German concept. It was supposedly called ''Chichibu'' and the USN was so convinced of its existance they built the Alaska-class "large cruisers" to fight it.

** HMS ''Cutlass'' is a [[http://en.wikipedia.org/wiki/C_and_D_class_destroyer C class destroyer]] of the Royal Navy. All the real C class vessels were by 1943 transferred to the Royal Canadian Navy, but two of the very similar D class remained in service. It's likely the mangaka just chose to use a C class to allow a name beginning with 'C', ignoring the minor historical inaccuracy. None of either class appear to have served in the Indian Ocean, however.

** USS ''Virgin'' seems to be completely fictional. Her 12" guns are rather larger than most cruisers carried; in real life only the ''Alaska'' class had guns that big among US cruisers. Very few US heavy cruisers during World War 2 that used single-gun enclosed secondary turrets, and none used 2x2 main turret configuration.

* ClothingDamage: Several times, but most notably with Captain Ann; Mamiya's katana strips her of everything above the waist, except for a shoulder holster with concealed second revolver and a [[CensorBox very conveniently placed]] leather strap across Ann's chest that ''just'' hides her nipples.
* CluelessAesop: [[spoiler:The Holocaust]] is brought up in Chapter 10 but isn't treated with any sort of depth, being used more as a plot device than anything. [[spoiler:Elsa's plotline]] does get a more serious treatment than most other characters', though.

* GlowingEyesOfDoom: Mamiya, especially when jealous of another girl paying attention to Kuki. Also Obama, if anything gets between her and sleep.

* HelloSailor: Nearly every female character is a lesbian, or at least bisexual.

* ImprobablyFemaleCast: And how. There's only one man on the ''Unebi'', the elderly, Zen Master-like Captain, no men at all on the U-800, and while the crew of the HMS ''Cutlass'' appear to be largely male, they're pretty much just a RedshirtArmy. The captured British seamen in chapter 1 have more of a speaking part than anyone else male; at first, they think they can escape, but seeing the women put on a [[{{Fanservice}} fashion show]] of new tropical uniforms convinces them [[AllMenArePerverts they might be better off]] where they are.

* KissOfLife: Kuki rescues Mamiya from drowning and performs this; of course Mamiya awakes with their lips touching, and falls instantly and completely in love. Kuki's [[SexySoakedShirt wet, clingy shirt]] doesn't help the lust aspect, either!

** Meanwhile, Gunnery Officer [[UsefulNotes/BarackObama Obama]] has a name that was possibly ''not'' chosen to be meaningful, but is a source of amusement nonetheless. Specifically when talking about her [[BiggerIsBetterInBed preferred equipment size.]] In addition, her first name, Mifuyu, translates as [[NamesToRunAwayFromReallyFast "Beautiful Winter"]].

** Well, Kuki makes an effort (of which her SelectiveObliviousness may be a part of), and Mamiya takes her job fairly seriously. In fact, most of the characters take their jobs seriously when it counts, but otherwise the military discipline amongst all three sides is pretty lackadaisical. On the other hand, if things weren't somewhat less grim and LighterAndSofter, [[JustifiedTrope then the story would be a lot less entertaining.]]

* MsFanservice: [[WrenchWench Gunnery Officer]] Obama [[NamesToRunAwayFromReallyFast Mifuyu]], one of the two out heterosexual woman in the series,[[note]]The other being Medical Officer Mukai, who's married.[[/note]] who's constantly unbuttoning her uniform shirt (she gets too hot in the tropics) and telling everyone how she needs a MAN. Royal Navy Captain Ann runs a close second, dressing as revealingly but in a far more obviously predatory way. Obama is ''just'' as predatory, however, it's just less obvious.

* ThoseWackyNazis: In a series that loves to play with tropes and stereotypes, the Germans are in no way excepted.

** The Chief at Penang shares Nina's smell fetish, and the general low opinion of Nazi ideology.

* TomboyAndGirlyGirl: the seaplane crew, short-haired cute little tomboyish pilot Kurushima Kiku ("Chibikuru-chan") and tall, calm, womanly HugeSchoolgirl-type navigator/gunner Nojima Atsuko ("At-chan"). They both bond over their pain of always being singled out because they're not normal height, among other things.

** Mary is determined to [[MurderTheHypotenuse kill Kuki]] in order to keep Ann's affections centred on her.

** Kurushima appears to be this, but it seems to be a symptom of something actually wrong with her. (See IllGirl below)

** Chapter 18, where we see the [[spoiler:Gestapo officer from Chapter 10 again. This time, he shows how truly despicable he is by '''hitting and pulling a gun on children''' and also hitting Obama for trying to stop him from shooting said children. Good thing [[BigDamnHeroes Chief Engineer Kobayakawa]] was there too to stop him via chokehold. What follows is some [[GroinAttack satisfying]] [[LaserGuidedKarma retribution.]] against the Gestapo bastard.]]

* IllGirl: It looks like pilot Kurushima is going to become one of these. Her clumsiness appears just [[CuteClumsyGirl cute and funny]] at first, but then we realize her right hand isn't working properly, even though nothing appears wrong with it. She's hiding it from her superiors, and thinks she's hiding it from her partner Nojima -- but of course she knows -- but isn't telling anyone because she doesn't want to fly with anyone else. Might be some kind of neurological damage.

* AbsoluteCleavage: Captain Ann wears her tropical uniform shirt like this; it's generally unbuttoned to below her breasts, which are definitely not supported by a bra.

* BlindingBangs: Chief Accountant Murakami hair always covers her eyes.

* PantyShot: Surprisingly few, but Mamiya gives one ''in her own imaginings''.

* {{Meganekko}}: Chiga, the ''Unebi'''s navigator, has large, thick glasses.

* SpotOfTea: The very first thing we see of HMS ''Cutlass'' is a teacup, that of Commander Mary -- who, we see in on the next page, sips her tea with pinky finger raised high, signifying her more ladylike, prissy demeanor compared to Captain Ann's more earthy and aggressive nature. Ann grasps her cup firmly. Tea leads to sex, naturally. The Unebi's captain is also frequently seen drinking tea.
