[[caption-width-right:200:Intro page of the manga, showing Commander Kuki (aka "Cookie")]]

''Kurogane Pukapuka Tai'' is a WorldWarTwo {{yuri}} comedy manga series following the exploits of the fictional {{Imperial Japan}}ese Navy commerce raiding cruiser ''Unebi'' -- which is entirely crewed by women except for the captain (who does nothing but drink tea, tend his bonsai, and sleep, it seems). They encounter a German U-boat, the U-800, also crewed entirely by women, and a British destroyer, the HMS ''Cutlass'', commanded by women; most of the women appear to be exclusively interested in the other women. [[{{BlatantLies}} Obviously, the historical accuracy here is high!]][[note]]Especially with the Nazi persecution of homosexuals in general and lesbians (to a lesser extent) in particular.[[/note]]

That said, the military details aren't utterly ludicrous; the mangaka is obviously a bit of a military {{otaku}} as well as a YuriFan. All the ships are fictional, of course, as are the military operations, though they're roughly plausible; there were commerce raiding cruisers and the like, described on [[http://en.wikipedia.org/wiki/Japanese_raiders_in_Indian_Ocean_Campaign The Other Wiki]]. The backstory of the ''Unebi'' is based on the raiders ''Aikoku Maru'' and ''Hokoku Maru''; the ''Unebi'', however, is a military vessel in outline, although supposedly construction began as a civilian ship, while the real-life raiders were civilian freighters in outline.

Most of the time, of course, it's simply a device to have sexy women-in-uniform fanservice and plenty of sexual and romantic girl-girl comedic action.

----
!!This work shows examples of:

* 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.
* AccidentalPervert -- supply captain Klaus Eder.
* AcePilot -- Kurushima, who evades a heavily-armed British fighter in her lightly-armed and unprotected seaplane. With her right hand not working.
* ActionGirl -- a lot of them, but Commander Kuki's unarmed repelling of the HMS ''Cutlass''' boarders is a good example.
* AllGermansAreNazis - avoided; chapter ten shows that Captain Nina is most definitely ''not'' a Nazi sympathizer. She is, in fact, [[spoiler: hiding a Jewish crewmember from the Gestapo]].
** {{Truth in Television}}: The Kreigsmarine wasn't very fond of the Nazis, since they poured the most money into the Heer and Luftwaffe.
* ArtisticLicenseShips -- largely averted; the {{mangaka}} did the research. All the main ships are fictional examples of their types, of course.
** 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 actually 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.
** The U-800 is a fictional member of the very real [[http://en.wikipedia.org/wiki/German_Type_IX_submarine Type IXC U-boat]], a long-ranged type quite possible to have in the Indian Ocean attacking British supply lines.
** 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.
** HMS ''Aldebaran'', which Captain Ann is transferred to command after the writing-off of the ruined ''Cutlass'', is a fictional member of the quite real Royal Navy [[http://en.wikipedia.org/wiki/Arethusa_class_cruiser_(1934) ''Arethusa'' class]] of light cruiser.
* AuthorAppeal -- the mangaka is obviously a [[{{Otaku}} military otaku]] and a YuriFan.
* BareYourMidriff -- the new outfits designed for Kurushima and Nojima for the fashion show.
* BeachEpisode -- U-800's all-girl crew visit Penang, a Malaysian island occupied by the Japanese which was really used as a U-boat base by the Germans in WW2. Beach volleyball in anachronistically modern swimsuits ensues, but the fun is abruptly ruined by the arrival of the Gestapo.
* BerserkButton -- Mamiya's is anyone who threatens or disrespects Commander Kuki.
** In case of [[{{Yandere}} Commander Mary]], anyone who attracts Captain Ann's attention.
* BetaCouple -- [[RomanticTwoGirlFriendship Kurushima and Nojima]], the seaplane crew. So far they're the only relationship shown that doesn't tie into the UnwantedHarem around Commander Kuki somehow.
* BlingOfWar -- many characters are pretty much only ever shown in full dress uniform with all the trimmings; Commander Kuki is always in Imperial Japanese Navy full-dress blues, and immaculately put together, while U-boat Captain Nina Stortebeker is in full Kriegsmarine dress uniform even after months at sea, including a Knight's Cross around her neck.
* BloodlessCarnage -- at first, and most of the time we don't see any deaths or even blood.
** For the first time we see someone seriously hurt (and for a while, [[{{Cliffhanger}} we don't even know how badly]]) in chapter 3, which is generally DarkerAndEdgier. It adds a somber undercurrent to the series. It puts us on notice that the characters can get hurt, and can die, and that they are really at war, and not just playing on the Lesbian Love Boat.
** On the other hand, no wounds result from seemingly more dangerous situations, like the British boarding attack on ''Unebi'' (during which no shots were fired), or the following [[DeathInAllDirections three-ship]], [[ThereIsNoKillLikeOverkill point-blank range]] [[MoreDakka cannonade]].
** [[PlayingWithATrope Played with]] after the battle with the HMS ''Aldebaran.'' Chapter 14 opens with a BurialAtSea, but it turns out [[spoiler:that it's really a funeral for the Shiokara Tonbo, the ''Unebi's'' seaplane.]]
* CallBack -- [[spoiler: The Gestapo officer from Chapter 10 makes another appearance in Chapter 18. Unlike in Chapter 10, though, this time, [[LaserGuidedKarma he doesn't walk away unscathed.]] Actually, the Gestapo bastard [[GroinAttack doesn't walk away at all.]]]]
* CallingYourAttacks -- Mamiya does this in her daydream sequences where she's chopping up warships -- "[[IKnowKarate Shin Mamiya Ryuu]]: Warship Slash!"
* TheCaptain -- each ship has one, of course, but Kuki seems to fill in for her boss a lot.
* CastFullOfGay -- of the female cast so far, only gunnery officer Obama has been portrayed as heterosexual.
* ClingyJealousGirl -- Commander Mary, who's very familiar with Captain Ann's wandering eyes and appetites. Ann generally silences her with a kiss, and the resulting PostKissCatatonia she seems to be so good at causing.
* 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.
* ComedicUnderwearExposure -- Done to the captured male British captain in chapter one, with a sword.
* CoolBoat -- the ''Unebi'', among others.
* DarkerAndEdgier
** Chapter 3, where blood is displayed for the first and (so far) last time in this manga.
** Chapter 10, which mentions [[spoiler: Shoah/The Holocaust]].
** 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.]]
* DaydreamSurprise -- we frequently get this, especially from Mamiya, who often lapses into dreamy-eyed imaginings of her rivals for Commander Kuki's love dying and Mamiya performing impossible feats of heroism to win Kuki over.
* TheDeterminator -- Mamiya, who attempts to [[OneManArmy conquer]] the HMS ''Cutlass'' [[TheBerserker by herself]], [[AttackAttackAttack oblivious]] even to her beloved Cookie's orders, in full GlowingEyesOfDoom mode, seemingly [[ImmuneToBullets impervious to the shells]] of the ''Cutlass''' main armament and [[MadeOfIron everything else]].
* {{Dojikko}}:
** Kurushima appears to be this, but it seems to be a symptom of something actually wrong with her. (See IllGirl below)
** Commander Kuki of [[DaydreamSurprise Mamiya's dreams]].
** A male example: [[AccidentalPervert Captain Klaus Eder]].
* DoubleStandardRapeFemaleOnMale -- this seems to be Obama Mifuyu's seduction technique.
* DualWielding -- Commander Mary, HMS ''Cutlass''' No.1., with twin (small) cutlasses.
* EnemyOfMyEnemy -- in love, at least; Nina asks Ann to "do something about her" (Mamiya); Ann [[LampshadeHanging wonders aloud "Aren't you two on the same side, anyway?"]]
* EveryoneCanSeeIt -- apart from [[SelectiveObliviousness Commander Kuki]], as it seems.
* FormFittingWardrobe -- the uniforms seem to fit rather more snugly than they should, unsurprisingly enough, particularly Kuki's and Mamiya's; they are tight enough to require spandex.
* FunbagAirbag -- Kuki stumbles into Mamiya like this; then Mamiya turns it into MarshmallowHell.
* FuroScene -- Obama, wakened from sleeping (in her bunk!) by the weeks-without-bathing stench of Captain Nina Stortebeker, strips her naked and throws her in the tub, followed by violent scrubbing with a broom. Then she throws [[HilarityEnsues all of the U-800's crew]] in the bath.
* [[GuyInBack Girl In Back]]-- Nojima for the ''Unibi'''s reconnaissance seaplane.
** Also true for the [[http://en.wikipedia.org/wiki/Fairey_Fulmar Fairey Fulmar]] fighter which Kurushima manages to evade (see AcePilot above).
* GirlishPigtails - Corporal Elsa Ebbers of the U-800, transferred to Unebi.
* TheGlomp -- Commander Mary on Captain Ann
* GlowingEyesOfDoom -- Mamiya, especially when jealous of another girl paying attention to Kuki. Also Obama, if anything gets between her and sleep.
* GroinAttack -- Done by Gunnery Officer Obama to [[spoiler: [[http://dynasty-scans.com/chapters/kurogane_pukapuka_tai_ch18#10 a Gestapo officer in Chapter 18.]]]]
** Even better, said [[spoiler: Gestapo officer is the same smug bastard that threatened Captain Nina Stortenbeker and Elsa Ebbers back in Chapter 10 making this a '''double''' LaserGuidedKarma situation.]]
* HelloSailor -- Lesbians, this time.
* HeterosexualLifePartners -- Kuki, Chiga and Obama (Mamiya not counted in for [[EveryoneCanSeeIt obvious reasons]]).
* HimeCut -- Mamiya's hair, which is always caught by a DramaticWind when she does anything appropriate.
* IllGirl -- it looks like pilot Kurushima is going to become one of these. Her {{dojikko}} clumsiness appears just cute and funny at first, but then we realize her right hand isn't working, 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.
** She fell down the stairs (http://www.batoto.net/read/_/132421/kurogane-pukapuka-tai_v1_ch3_by_wings-of-yuri/4)
* ImplausibleFencingPowers -- Mamiya, who manages to inflict ClothingDamage on British merchant seamen who don't respect her Cookie, slices Commander Mary's scimitars in half with her [[KatanasAreJustBetter katana]], deflects Captain Ann's bullets and then cuts her revolver in half ...
** As a consequence, Mamiya is also ImmuneToBullets and a [[OneManArmy One Woman Army]].
* 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.
* KatanasAreJustBetter -- at least in Mamiya's hands; she defeats other swords, guns, and is taking on the 4.7" guns of HMS ''Cutlass'' armed only with one until events intervene. Of course, even this doesn't match her dreams of glory in which she chops up whole fleets ...
* 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!
* LadyOfWar -- Mamiya.
* LuminescentBlush -- many of the cast, but especially Mamiya, when caught being too obvious about her obsession with her commander.
* MeaningfulName -- Commander Kuki, whose nickname, "Cookie", has all the intentional DoubleEntendre meanings. All the girls want to eat her, and all that.
** Meanwhile, gunnery officer [[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 [[BiggusDickus preferred equipment size.]]
** Not to forget Obama's first name -- Mifuyu, which translates as [[NamesToRunAwayFromReallyFast "Beautiful Winter"]].
* {{Meganekko}} -- Chiga, the ''Unebi'''s navigator.
* MildlyMilitary: They're not even trying...
** 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.]]
* MoodWhiplash -- between comedic and dramatic, for one thing.
* MoreDakka -- seems to be the favourite tactic of Captain Nina and Obama.
** In case of the latter, see also ThereIsNoKillLikeOverkill for firing the warship's [[{{BFG}} main battery]] at a point-blank range.
* MsFanservice -- [[WrenchWench Gunnery officer]] Obama [[NamesToRunAwayFromReallyFast Mifuyu]], the only out heterosexual woman in the series, who's constantly unbuttoning her uniform shirt (she gets too hot in the tropics) and telling everyone how she needs a [[BiggusDickus 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.
* NamesTheSame--Obama obviously with the [[BarackObama President of the US]].
* NazisWithGnarlyWeapons -- the U-800, captained by Nina Stortebeker.
** [[RuleOfCool Of course]], Nina's handgun of choice could be none other than a [[CaptainObvious Luger]].
** She also seems to be carrying around a ''[[WhipItGood whip]]'' for some reason.
* {{Nosebleed}} -- Commander Kuki tends to have this effect on Mamiya. Later, Nina exploits this to stop Mamiya's UnstoppableRage [[spoiler:by stripping Kuki in front of her]].
* NotWhatItLooksLike -- right there in the first chapter.
* NumberTwo -- Each ship has one. Technically, Kuki is #2 on the ''Unebi''. Mary on the ''HMS Cutlass''.
* ObliviousToLove -- Commander Kuki, and how! Although one wonders, given her tendency to get so very flustered when women make advances to her, whether this is more a matter of [[SelectiveObliviousness willfully not seeing things she's not ready to deal with.]]
* OjouRinglets -- Gunnery officer Obama ([[BarackObama not that one]]), possibly the only heterosexual woman on the ''Unebi'', and certainly the only one we've met yet. Her {{BFG}}s (12" guns from an old battleship) are not compensating for anything, honest.
* OneHeadTaller -- the crew of the ''Unebi'''s observation seaplane, short pilot Kurushima and tall navigator/gunner Nojima, with plenty of opportunity for this trope to show up.
** Also Mamiya and Cookie, and Ann and Mary.
* PaintingTheMedium -- Commander Kuki rips Obama's speech balloon because of its lewdness.
* PantyShot -- surprisingly few, but Mamiya gives one ''in her own imaginings''.
* PostKissCatatonia -- Captain Ann has this effect on women when she kisses them. She's nicknamed the [[NamesToRunAwayFromReallyFast Devil Kisser]] because of this.
* PreAssKickingOneLiner
** "Don't you look down on [[CoolPlane Shiokara Tombo]]!!" -- Kiku
** "Your head will be my trophy!" -- Mary
** "I will cut you all... into small pieces." -- Mamiya
** [[spoiler: [[SarcasmMode "These are actually]] [[GroinAttack kinda cute."]]]] -- Mifuyu Obama
* RevolversAreJustBetter -- in the opinion of Captain Ann of HMS ''Cutlass'', who carries a big Webley.
** Reasonably historical, as it was the current British service sidearm.
* ScheduleSlip: It appears that after a gap of a few years, Vol.2 is now out in Japan.
** Mainly due to MC Axis, the magazine that this series is serialized in, is seasonal and is published every 3 months.
* {{Shotacon}} -- Gunnery officer Obama Mifuyu's headed toward that territory as of Chapter 18.
* ShoutOut -- An end-illustration to chapter 1 has commander Kuki and XO Mamiya acting out the "I'm the king of the world!" scene from ''{{Titanic}}''. Good thing they're in the tropics, no?
** In chapter 15 there's an intro based on ''[[LightNovel/MariaSamaGaMiteru Maria Watches Over Us]]'' in the light novel written by [[spoiler:Chiga]] and published by Murikami.
* 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.
* StockUnderwear -- the British merchant captain whose clothes are cut off him by Mamiya is wearing stripy boxers/long underwear, while the Captain, as befitting a traditionalist, wears [[http://en.wikipedia.org/wiki/Fundoshi fundoshi]] (we see him towelling off bright and early in the morning after, presumably, a brisk cold shower, as part of his unchanging daily routine.)
* ThereIsOnlyOneBed -- When Commander Kuki lets Mamiya stay in her quarters after Mamiya's quarters suffered battle damage.
** It is unclear as of yet whether this part was an example of Kuki's actual [[TheDitz cluelessness]], an extreme case of [[SelectiveObliviousness self-denial]] on her part, or a [[CovertPervert thinly-veiled invitation]].
*** Another possibility is that Commander Kuki simply enjoys Mamiya's suffering.
* ThoseWackyNazis -- in a series that loves to play with tropes and stereotypes, the Germans are in no way excepted.
** Captain Nina Stortebeker is a blonde, warrior-braided valkyrie straight out of Wagner. She [[PuttingOnTheReich puts on the Reich well]], almost always appearing in full-dress uniform with a Knight's Cross at her throat, but with individualistic touches as befits a submarine commander, a breed not given to too much conformity. Her peaked cap is generally off-center and her sleeves are rolled up. She also fits the Nazis-as-perverts trope, with her obsession for the ripe odor of her "maidens" after weeks at sea, which is shown as a spiritual connection to her crew in her mind. Nina also carries a whip, playing further into that trope. She also meets the Oskar Schindler trope, since we find out she's been hiding a Jewish crewmember from the Gestapo.
** The Chief at Penang shares Nina's smell fetish, and the general low opinion of Nazi ideology.
** The Gestapo officer sniffing around Nina and her crew is the complete stereotype, complete with pince-nez glasses la Himmler.
* ThreePointLanding -- after sliding down a rope to repel boarders from HMS ''Cutlass'', Commander Kuki lands in this stereotypical shonen action hero manner.
* 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 [[RomanticTwoGirlFriendship bond]] over their pain of always being singled out because they're not normal height, among other things.
* {{Tsundere}} -- Kurushima Kiku.
** Commander Mary might also count.
* UnwantedHarem -- Commander Kuki is desired by at least three women: her XO, Mamiya; German U-boat commander Nina Stortebaker; and British Captain Ann. All three are very competitive. Ann, [[LoveDodecahedron meanwhile]], is desired by her Number One, Commander Mary.
* VaporWear -- Captain Ann, almost certainly.
* TheVoiceless -- the ''Unebi'''s captain, who has spoken exactly once so far.
* WouldHitAGirl -- [[spoiler: The Gestapo officer from Chapter 10 appears again in Chapter 18 and smacks away a little girl trying to sell him fruit. The girl's brother throws fruit at him for hitting her and the officer '''[[MoralEventHorizon pulls a gun on them]]'''. Luckily, [[BigDamnHeroes one Gunnery Officer Mifuyu Obama saw all of this and stops the gun from firing by blocking the hammer of the gun then she calls the Gestapo officer out for being extreme in his methods, especially to just a bunch of kids.]] The Gestapo officer then also slaps Obama and points the gun at her too before [[BigDamnHeroes Chief Engineer Kobayakawa puts the Gestapo officer in a chokehold.]] What follows is some [[GroinAttack satisfying karmic retribution for Obama against said officer]]...]]
* YamatoNadeshiko -- Mamiya, the ''Unebi'''s executive officer. She has long black hair in a HimeCut and carries a katana; what more could you want?
* YourFavorite -- Nojima knows exactly how to cheer Kurushima out of her funk after their seaplane is damaged in the storm; canned pineapple, which is clearly Kuru's TrademarkFavoriteFood.
