If you're wondering about that weird thing that keeps popping up all overJapanesewebsites as of mid-2013, then you might be in the right place.Kantai Collection (艦隊これくしょん, meaning Fleet Girls Collection, abbreviated as KanColle/KanKore for short) is a free-to-play browser Collectible Card Game developed by Kadokawa Games and hosted at DMM. It was launched on 23 April 2013, and has since then experienced a surge in both exposure and popularity, with around 800,000 registered users as of September 2013 alone, and a million users come October. The massive growth of the fandom surrounding it has given rise to comparisons to the Touhou Project, particularly among Pixiv users.note Or Strike Witches, for Western ones.The gameplay is centered upon a card battle game, with individual characters represented by various cards with different attributes. Each of the characters are moe anthropomorphisms of World War II naval warships which are depicted as cute girls, known as "Fleet girls" (艦娘, kanmusu, literally "ship girl"). These personified warships are based on real-life vessels which are explained in detail within the game; the physical characteristics, appearances and personalities of each of the girls correlate in some way to the real-life vessel (for example, ships with a larger displacement tonnage are often depicted with larger breasts, with the notable exception of a few aircraft carriers...and oddly enough a pair of very small light cruisers who get depicted with large breasts). The player takes on the role of an admiral (提督, teitoku), who can be either male or female, and organises their fleets in battle in order to win. Combat is largely automated, and manual actions by the player include micromanagement such as building and repairing.So far the series is the focus of an online comedic 4koma following Fubuki the destroyer and her friends as they go through fleet training under the guidance of other heavier ship classes, but three more manga were announced recently, all getting serialized in different magazines (Comic Clear, Comptiq, and Monthly Comic Alive respectively). This is in addition to a much more serious Light Novel written Tsukiji Toshihiko, which will come out at the end of 2013.An anime series as well as a Playstation Vita game for the series have been announced, though no definite date so far has been released for either.Compare to Arpeggio of Blue Steel, which also features female personifications of WW 2-style battleships. Not to be confused with Sengoku Collection, which has genderflipped Sengoku warlords instead.A Character Sheet is under construction, all help welcomed.
Kantai Collection features the following tropes:
A-Cup Angst: Tone's sensitive to how Takao and Atago have larger... displacements, compared to her in the 4koma. Light Carrier Ryuujou is also portrayed like this in fanworks, to the point where its joked that she has an extra "flight deck" just in case her scroll gets destroyed.
Always Night: It always is for Sendai. Many fans depicted her as the girl who sleeps during the day, but active during the night. Her lines in the game are always about night, and is nicknamed Night War Idiot (夜戦バカ、Yasen Baka).
Which is based on her Real Life actions: three out of four main battles she participated in are night battles.
Anachronism Stew: While the period in which the game sets is not specified, many found it awkward when Imuya mentioned Smart Phones.
Musashi actually shown hints of being technological savvy, and is depicted to be able to catch on the present popularity as well. But considering what has been mentioned above, it'll take a while until DMM & Kadokawa settles down with a proper period.
Anyone Can Die: Prospective admirals beware, once a ship girl is sunk (when their HP is reduced to zero), they're not coming back, unless you happen to have a special item equipped on her beforehand (that can only be bought using real-world money!) to make an emergency repair on-location. Even then, it's a one-time deal, and if the same kanmusu gets critical damage again, that's it for her.
Archer Archetype: The entirety of the Standard Aircraft Carriers (like Akagi) as well as 3 of the Light Carriers are portrayed as samurai archers.
Awesome but Impractical: Heavy Cruisers for starter admirals, and Carriers and Battleships for experienced ones. All of this due to their expensive maintenance costs that can really put a dent on an admiral's resources, and significant repair times whenever they're damaged. Superbattleships Yamato and Musashi take this to extremes, as they use as much as three times the resources to refuel and re-arm, and takes twice as long to repair even when compared to Nagato, who is herself already a massive resource sink.
Bare Your Midriff: Shimakaze, Yuubari, Ooi Kai2, Kitagami Kai2 and the Nagato-class sisters.
Berserk Button: Hurt Kitagami and you'll be receiving Ooi's lovely torpedo shots, so don't do it. note The line strangely do not appear once she is upgraded to Kai2.
Beware the Nice Ones: Tatsuta. While she can be very soft spoken and gentle, along with a nice and healing smile. Her dialogue in the game will tell you that it's best not to mess with her unless you do not miss the hand that harassed her.
Big Eater: Carrier Akagi. While all carriers are resource drains (true for any ship class above Light Cruiser really), Akagi's so far the only kanmusu who has this as a character trait in official media. Indeed in the 4koma, Bauxite runs are nicknamed "Akagi's feeding time". Her infamy for being such a Bauxite hog stems from the fact that, unless an admiral somehow lucks out during construction, she's the first Standard Carrier he or she will get (due to her being a quest reward), and she will VERY quickly use the Bauxite stores (as its used for maintaining her planes).
Big Sister Instinct: Fusou is an example of this, as she thinks of her sister, Yamashiro's well being most of the time.
Fusou: ''Please look after my younger sister, Yamashiro's modernization as well"
Boobs of Steel: Naturally comes with being the personifications of warships, especially more so on the more well-endowed ones. Yamato sports an almost literal definition of this.
Born Lucky: While it's still unclear just what the Luck stat actually does in the game other than affect the probability of a cut-in attack, an observant admiral will notice that certain ships will have higher-than average luck. Those who also happen to have more than a passing knowledge of World War 2 naval battles will note that the majority of these ships either lasted to the closing months of the war (Aoba, Ise, Hyuuga), actually survived the war (Yukikaze, Nagato, Houshou, Kitakami), or somehow avoided or survived damage that had easily taken out their sister ships during a particular action (Hiryuu and Zuikaku) before they themselves got sunk. Yukikaze in particular not only survived more major battles than she had any right to, but she also served as flagship of the Taiwanese navy before finally being dismantled in 1970. Her luck stat of 60, higher by far than any other ship in the game, reflects this.
Prior to her sinking, Shigure was also regarded as a miracle ship not unlike Yukikaze, for the same reasons. Her luck stat of 50 in her Kai 2 form (second only to Yukikaze) reflects this.
Born Unlucky: The Fusou sisters act like they are the resident Cosmic Plaything. This is based on the fact that being the first native attempts to design a super-dreadnought, their design was... well, horrible and plagued with numerous problems. The military realised that too, and they are never really being taken seriously as a result. The Curb-Stomp Battle of Battle of Surigao Strait where they meet a gruesome demise does not help either.
Mutsu had it worse, and it was actually portrayed in-game when compared with the Fusou sisters - with 3 luck compared to the latter's 5. See Woman on Fire for the reason why.
Kumano is also another unlucky one (her in-game profile heavily hints it): In real history, Kumano was attacked 7 times (possibly more) during her entire life of service, and her fate is particularly gruesome where she came under aerial attack by aircraft launched by USS Ticonderoga, which five torpedoes and four 500lb bombs struck her, all of that happened while undergoing repairs in Santa Cruz. Even the US navy admiral actually felt sorry for her demise.
Buxom Is Better: The Takao sisters. Even somewhat lampshaded by Atago in the game's database section, where she mentions how her... fuel tanks, are heavy and make her shoulders stiff.
Tenryuu and Tatsuda also have ammo storage that is several tiers higher than other light cruisers.
Breaking the Fourth Wall: As stated above, aside from Musashi who is cool with you closing your browser window when you actually leave the game for a while, Agano and Yahagi (especially Yahagi) also mentioned along the lines of clearing off daily quests, which you, the player are somehow obligated to do this on daily basis in order to earn resources and instant repair buckets.
Bribing Your Way to Victory: Some account enhancements (like extra slots in the dock), a good chunk of the consumables in the in-game store, extra resources, and high-end furniture that require custom furniture craftsman can only be purchased through points, which can only bought via real-world money. Can be particularly galling for players, as while the other contents of the store can be found via expeditions, one important consumable (Emergency Repair, which prevents unplanned sinkings), can only be bought this way.
Even so, all the items mentioned above are entirely optional and players have the option to not resort to purchasing them in order to win the game. Given that getting the ship daughters involve either being lucky with drops, building, or clearing (often extremely hard) certain levels during timed events, paying with real money does not really help either (unless you pay A LOT).
Cast Herd: With the huge cast as well as the various historical and in-game interactions, there's several dozens of groups available. This goes from ship types* Destroyers, Aircraft Carriers..., ship classes* Fubuki-class Type III(Akatsuki-class), Shoukaku-class... and divisions* DesDiv6, CarDiv5... to historical fleets* The Mikuma fleet used at Savo Island and ship-girls who look like each other* Takao and Atago, already sister ships, have been collectively called the "Takao sisters".
Clothing Damage: A visual representation of your ships' condition. Rule of thumb is (aside from the obvious smoke from their icons!) the more tattered and ratty each girls clothes are, the more damaged they are.
Colbert Bump: Originally intended to be a niche game catering mostly to the military otaku population with a modest budget and minimal advertisement, its popularity experienced a huge surge after its players (including, among others, KohtaHirano, whose Heroic BSOD on twitter being most commonly cited as the main reason for the popularity surge) spread the word on Twitter and/or Pixiv.
Cool Big Sis: A lot of lines heard from the game can evoke this particular trope. Especially Hiei's admiration to be like Kongou, or Yamashiro's admiration towards her sister, Fusou.
Cosmic Plaything: While not so obvious in the game, Shōkaku hints herself as one unlucky girl (or depicted by fans as one, especially when receiving minor damage), thanks to how she was treated during the war, by Japanese accounts. Her database even introduced her as "the ship that received terrible fate during that war (Battle of the Philippine Sea)".
Displayed prominently in the 4koma where, in quick succession, she gets pooped on by a passing bird, and gets hit in the head by thrown rock, and had an empty pail dropped on her. The fact that she's such a magnet for misfortune (aside from the obvious real-world WW 2 references) causes Kaga to be terrified of her, once she learned that both Shoukaku and Zuikaku were joining the fleet.
Covert Pervert: Shirayuki in the 4koma, which causes Fubuki to be more than a little worried. Also Sendai, who likes seeing other girls get wet in the rain as it makes their underwear visible.
David Versus Goliath: Invoked by mission 3-2, where the boss node can be only accessed by a fleet of destroyers, the smallest class of warship (whose high evasion values are offset by having the lowest damage, hit point, and armor values of all non-submarine unit) available to an admiral. They're expected to battle elite battleships and heavy cruisers. The fact that many destroyers (like Akatsuki, Inazuma, Ikazuchi, and Hibiki) are portrayed as middle-schoolers or younger just strengthens the impression, especially since the Abyssal Fleet ships they're going to battle look like adult women or saurian monsters.
Do Not Attempt: One of Kitakami Kai 2's line, as well as of I-58, mentions about her request to never attach that weapon on her. The weapon in question is Kaiten, a human torpedo that Kitakami used to actually carry during her service in war. Kaiten is also well known for sinking USS Underhill, but considering such heavy price in using this weapon, It'd make sense for Kitakami to reject this equipment.
Eldritch Abomination: Many of your enemies fall into this trope. Sure some sport a more humanoid form, but that doesn't make them any less of a monster.
Embarrassing Nickname: Yamato is nicknamed "Hotel Yamato" or simply "Hotel", which embarrasses her from time to time. The reason once again came from the fact that Yamato had a real history of being treated as one - At that time when she was secretly built by the Imperial Japanese Navy, the people had the mindset of "Aircraft Carriers are the best, Battleships are just a bonus/ an alternative". That, and adding her status as a flagship along with her high consumption, causes Yamato to spend most of her time at the bridge until 1944 (Battle of Leyte Gulf), leading her to be nicknamed "Hotel Yamato". Historically, the term is also taken from a real Yamato Hotel which was located at Manchuria (presently Dalian, China).
Interestingly, although it was considered a luxury to ever spend a night in the ship's bridge, the purpose of Yamato maintained true to the core. Still she was quite unfortunate, participated mostly in escort missions instead of offensive operations.
Yamato: 'H...Hotel!? N-No, you're wrong!"
The whole Yamato being treated as a hotel is played with in the official 4-koma manga, like how she was equipped to manufacture iced cream and was fully air-conditioned (both of which were true of the real battleship). The little destroyer girls loved hugging her as a result.
Foolish Sibling, Responsible Sibling: Despite being the instructors of the Destroyers in the 4koma, Ise is regularly characterized as far less serious than her sister Hyuuga, the latter of whom actually got annoyed at Ise's need to be the center of attention.
Foreigners Write Backwards: Due to the history of how traditional Japanese is written, Shimakaze can also be written as "Zekamashi". Inazuma's verbal tic "Nano-desu!" is also played with, which becomes Sudenona!.
Fragile Speedster: Sure, Shimakaze is fast, but her average stats on other aspects will mean she will still be fairly vulnerable to enemy attacks at low level. Oh, and It hurts, due to being a Destroyer.
Every Destroyer class ships are like this. They have paper thin armor and low hp pool but fast and have high dodge rate that can get even better with equipment.
Genki Girl: Kongou is the famous example of this trope. But some characters like Nenohi, Ikazuchi, Ooshio, and Naka count as well.
Glass Cannon: Yuudachi Kai2, when maximized, has raw firepower in par with most maximized heavy cruisers with a fraction of the resource usage. However, as a destroyer, she still has very little health.
Kitakami Kai2 and Ooi Kai2, when maximized, can potentially deal as much damage with their torpedos as Yamato can with her cannons. With mini-subs (which lets you start attacking with torpedos before shelling), you can potentially destroy particularly difficult ships before the real fight starts! However, as they start as light cruisers, they can't really take much of a hit. Certainly not as much as damage sponge Yamato.
Goroawase Number: I-168 and I-58 have chosen to do this with their names to make them easier to pronounce and to make them sound more like actual names. Thus, I-168 and I-58 are also known as "Imuya" and "Gouya" respectively. For the same reasons, I-19 and I-8 are called "Iku" (no, not that Iku) and "Hachi".
Gratuitous English: Kongou, who enthusiastically shouts lines like "BURNINGLOVE!" for her attacks. Based on the fact that the real-life Kongou was built in England.
Gratuitous German: The "obligatory-German-speaker-in-a-game-with-WW 2-references" here is I-8. Based on the fact that I-8 was the only Japanese submarine to have attempted and succeeded a round trip to Germany during WWII.
Gratuitous Russian: Hibiki sometimes talks in Russian. She has more lines in Russian after she gets her final upgrade into the Verniy.
Hair Decorations: Unsurprisingly, they are all over the place. Some of the most impressive examples comes from the battleships with Yamato's "Sakura and Radar Mast" thing going on, the Fusou-class' pagoda mast being portrayed as these, Nagato and Mutsu's head apparatus and the Kongou-class' signature winged headset.
Heroic BSOD: Any mention, intentional or otherwise, of the events surrounding the sinking of the real-life Akagi in the Battle of Midway is enough to turn Akagi into a panicked and quivering wreck in the 4koma. Played for laughs though, as apparently feeding her with her favorite Bauxite is enough to snap her out of her episode.
In another instance, Kongou also suffered from trauma from the model because she was the only Japanese battleship to be sank by submarine, although not the same class as Albacore. In the same vein, destroyers in general tend to suffer trauma from submarines in general, as shown in the official 4koma.
Hidden Buxom: Ushio, she is the only Destroyer-type (and only in her group) who has a nice stack. This can only be seen when she receives◊ critical damage.
Also Naganami and Yuugumo.
Hime Cut: Hatsuyuki. Murakumo, Hiyou and Shouhou have decorated variants. Also if you let loose of her hair, Kitakami's hairstyle is considered one as well.
Historical In-Joke: All over the place, especially apparent in the 4koma. That said, the real-life references of the ships each girls represent are more often than not played for moe points instead.
Hot-Blooded: While most kanmusus have lines that show their spirit and passion when fighting, Suzukaze is particularly high spirited and hotblooded in almost everything she does.
Inferiority Superiority Complex: Kaga towards the Shōkaku-class sisters (Shōkaku and Zuikaku). In real life, the Kaga was the slowest and generally worst-designed of Japan's large fleet carriers, while the Shōkaku-class were arguably the best and certainly the most advanced pre-war design.
I Shall Taunt You: The frequency of Naka's appearance in this game, be it crafted (especially if people are aiming for a battleship) or obtained, irritates some players. Even if it's not intentional, the RNG mechanics of this game is somewhat cruel that poor Naka gets treated this way.
Item Crafting: There are two usual ways to gain additional ship girls in the game. One is via random drops during sorties or expedition. The other way is constructing one, a much more time-consuming process that uses up resources (fuel, ammunition, steel, and bauxite). Specific resource ratios during construction yield higher chances of getting "rare" ships (like Shimakaze or Yukikaze), or even ship types (in case of carriers). Even so, to get exactly what you want, is a hit-or-miss thing.
Jack of All Stats: Ships belong to Heavy Cruiser class tend to be this. They are average in every stats and can hit anything in the game with suitable equipment.
Master of None: Occasionally falling into this category for the same reason, as you can only field no more than six ships, regardless of types, in your fleet.
Japanese Politeness: Haruna, and Hōshō. They stand out when compared to other characters in the game.
Japanese Pronouns: The stardard here is still "Watashi" (私). However, with the number of characters with odd speech patterns, there's also a good number who also use other pronouns to refer to themselves.note Also, quite a few don't have any lines outside of their introduction in which they refer to themselves at all or even, they always refer to a different person than themselves or the admiral.
"Atashi" (あたし): Jun'you, Kako, Maya... (those three have rougher speech patterns, though).
Lethal Chef: Kongou and Hiei, after their second remodel, exposed them as a terrible cook. In comparison, Hiei is the worst. How bad? Her curry makes the admiral running around avoiding her for 2 hours. You're free to imagine what happened to the admiral during that time.
Lethal Joke Item: The kotatsu, played with in the official 4-koma. It makes nearly everyone useless (as in, they completely lost their will to sortie), even Yamato.
Loads and Loads of Characters: As of writing, there are 118 unique collectable fleet girls of various types with 22 upgraded variants, and this isn't including the admiral's support and maintenance staff, or the so-called "generic" enemies which compose the Abyssal Fleet.
Magikarp Power: Chitose and Chiyoda, the only Seaplane Tenders in the game, start out pretty useless except for scouting purposes, but after five remodeling sequences, they become very cost-efficient Light Carriers whose carrying capacity is on par with lower tier Standard Carriers Soryuu and Hiryuu with better fuel consumption.
Some Destroyers with Kai2 form also count as this trope, namely Hibiki/Verniy, Yuudachi and Shigure. Sure, they have high remodeling levels, but once remodeled they can outperform Light Cruisers and even some of Heavy Cruisers with significantly lower cost. As destroyers, they also have 5x night battle damage bonus and high evasion, making them very useful in late-game or event stages where night battles are frequent.
Man of a Thousand Voices: Most of the game's actresses have more than five different roles (often voicing all the ships of a given class) and as such get the chance to showcase their versatility. Who would guess that Nagato, Shimakaze, and Jintsu are voiced by the same person?
Mooks: The game's primary objective is that you sort your team of 6 to fight demon ships, known as the "Abyssal Fleet" (深海棲艦, Shinkai Seikan). Similar to your compositions, they also have different types of mooks to go against you. But beware, these mooks aren't simple to defeat thanks to the game's unpredictable, automated system. You may even come across Elite Mooks, Airborne Mook, Aquatic Mook, and many more of these as you progress.
No Export for You: The only way to play the game is to register on the Japanese-language segment of the DMM website, which itself is inaccessible to non-Japanese IP addresses. This means to even register for the game, a prospective non-Japanese player will have to jump through a lot of hoops to do so (usually by using VPN), nevermind getting to play the game, which then requires newly-registered members to win a lottery for one of the limited slots per server. And competition is steep for server slots.
Nonstandard Character Design: Due to using different artists, some of the girls may look sharply different from a class to another and even within classes. For example, compare Yukikaze's design with the design of the other Kagerou-class ship girls or compare Murakumo's design with the design of the rest of the Fubuki-class and the design of the first two of the Hatsuharu-class.
Non-Entity General: The admiral/teitoku commanding the fleet of kanmusu, basically acting as the player's self-insert. This obviously results in (male) admirals having wildly different portrayals in fanwork, though it also makes a large segment of Pixiv artists simply replace the admiral's face with a 'T', much like how the Producer in Petit Idolmaster has a 'P' for a head. Female admirals somehow avoid the T-head, but still end up looking suspiciouslyfamiliar anyway...
No Plot? No Problem!: Either this, or the game has a very very flimsy Excuse Plot if one squints hard enough. Proponents of the latter point to how the missions range further and further afield, starting with clearing out the waters around the naval district, before culminating in a raid at the Abyssal Fleet anchorage, complete with supporting bombardment by another squad of allied ships from your fleet.
Ojou: Definitely Kumano. Speaks like one, acts like one as well.
Onmyodo: Light Aircraft Carriers Hiyou, Jun'you and Ryuujou uses shikigami paper planes. Their flight decks are represented as a scroll with an image of their flight deck printed on it.
Out of Focus: Poor Fubuki, being the poster girl of her own game, only to get overshadowed by more popular characters like Shimakaze, Kongou or even Inazuma/Ikazuchi. Alleviated a bit in the 4koma, where she and Shirayuki are the viewpoint characters.
Pointless Band-Aid: Oboro has a few of these. And yet, she is still the bland one of the Des Div 7 sisters (Sazanami has her twintails, bunny and badge. Akebono has her sidetail and the tendency to treat the Admiral like shit. Ushio has boobs and that pink cannon of hers).
Power Up Letdown: Battleships or standard carriers could be considered as one as their upgrades, while considered an overall improvement since it raises their stats, experiences letdown on other important aspects like its double repair time and the resources required to repair them. It could be worse if you're participating in events where its end stage could often damage your ships critically, resorting to use instant repair buckets and a significant amount of fuel, ammo and steel to repair and replenish them. note Do note that the limited time available for the players to clear the event, plus the bosses' regeneration ability often are the reason why people opting to spend resources and buckets to get them fully healed as quick as they can.
Some ships (such as Fubuki, Ooi and Musashi) suffer a decrease in luck after their remodelnote for Ooi though, Ooi Kai 2 upgrades her luck from 10 to 13.
Proper Lady: Subverted by Akatsuki. She proclaims herself to be one, acts seriously and does her best to be as one, but her miniature stature is hard for others to take her seriously, which makes her frustrated. Some of her lines in this game justifies how she is treated.
Akatsuki: ''I'm NOT a kid!" (when attacking)
Race for Your Love: Kongou, oh Kongou. There is a reason why the term "Teitoku LOVE" is famous among the Japanese fans. She is out to gain your affection, dear Admiral.
Kongou: ''I'm the one who will capture Admiral's heart!"
Random Number God: Oh god RNG really is everything in this game. Even if you manage to find some construction or development recipes that lead you to what you want, be very careful not to get too worked up. You will regret it.
Sailor Fuku: Not surprising, given this is a game about anthropomorphized ships, that variations of these show up worn by the girls, most obviously among the various destroyers.
Sarashi: The Kongou-class sisters as well as Musashi wear it. Musashi wears only a sarashi to cover her her chest, while the Kongou sisters wear theirs under their shirts.
School Swimsuit: I-58 and I-168, 2 of the only submarines in the game as of current, wear school swimsuits covered by upper half of their school uniforms as their unifying theme. I-19 and I-8 both wear only the swimsuit.
She Is All Grown Up: Isuzu Kai II and Yuudachi Kai II (and to a lesser extent, Verniy). Compare them to their base forms, and the difference is staggering.
Sugar and Ice Personality: Kaga is normally this, even to you. The only exception to this is her interaction with Akagi, be it in doujins or even in the official 4-koma manga. However she is not that stoic as she does offer her ears for you if you need to talk to her about something, be it for official or personal matters.
The Dev Team Thinks of Everything: The fourth event boss of Fall 2013, Airfield Princess (飛行場姫, Hikoujyo Hime) is known by many Western fans as Henderson Field personified as a scary looking female. Some thought that as a building, the battle itself can't be T-crossed (basically a battle situation that is extremely unfavorable to your side as well as the enemy). But you have to remember, as Henderson Field is now an opposing unit in this game, that technically means she is a character, hence even if she is piece of South Pacific real estate she can T-cross you. You would have to give credit to the developers who thought of this though.
The Lad-ette: Maya is the offender of this trope. If you know Japanese, just listen to her lines. Doesn't help that her attire may cause you to think of her as a typical pottymouth sailor.
The Rival: A lot. Just to note some examples (be it in fan depictions or official):
Fusou and Yamashiro towards Ise and Hyuuga. This is due to the fact that real life Ise and Hyuuga were created as an improvement towards the design flaw caused by Fusou and Yamashiro.
Kirishima towards Haruna. Reasons are due to production rivalry/competition between Kawasaki Shipyards in Kobe (which built Haruna) and Mitsubishi Shipyards in Nagasaki (which built Kirishima), all around the same time. However, Kirishima's production got delayed for a daynote On the contrary, Haruna's engine was actually found faulty during her engine test. As result the construction ended up taking extra 6 days to complete, and the person who was responsible in the production of the engine committed suicide in order to apologize for his mistakes., which caused Kirishima to look at her as a rival, despite they were both completed at the same day, effectively making them twins. Do note that the whole rivalry is actually one sided as Haruna does not actually think much of it.
Kaga towards Shoukaku and Zuikaku. Kaga belonged to the First Carrier Division, while Shoukaku and Zuikaku belonged to the Fifth Carrier Division. Since both divisions couldn't get along well during the war due to complications (mainly because of how they think soldiers from the Fifth Division Carrier were amateurs), their rivalry began. Some lines in the game justify Kaga's uneasiness towards the Shoukaku sisters.
Kaga: ''Don't put me on the same league as the Fifth Carrier Division."
The Stoic: Kaga is one, but the winner goes to Shiranui, who is arguably more stoic than Kaga.
Verbal Tic: Several of the girls have one. Kuma has "-kuma", Tama has "-nya", Arare has "n'cha"...
Somewhat enforced both in several fan depiction and (later) the 200k user special scroll, where Kiso, the only one in the Kuma-class to NOT have a verbal tic struggling to have one ("-kiso"!) herself.
Yuudachi has "-ppoi?", which roughly means "it is like...?"
I-19 loves to end her sentences with a "-no"
Walk on Water: For obvious reasons, this is a common ability of the ship girls. When it came to this, the official 4koma compared it to ice skating.
Woman on Fire: Mutsu always mentioned in the game along the lines of "Don't play with fire". There is a reason behind that: The real life Mutsu's no.3 turret exploded on June 8, 1943 when Mutsu was moored in the Hashirajima fleet anchorage. It is concluded that the explosion was most likely caused by a disgruntled, suicidal crewman who sabotaged and set the fire around the turret, although the true story behind the explosion remains a mystery. Regardless, the result of the explosion caused Mutsu to literally split into half. If you put it this way, she was indeed, literally on fire. note This overlaps her of being born unlucky, and is also the reason why she spent her service life seeing very little in actual combat, enforced even more by her stat in-game. One of the other ships witnessing her sinking was, ironically, Fusou.
Yandere: Ooi is hinted to be this in game, as she is very clingy and violently protective towards her best friend Kitakami. Fortunately this treatment is not extended to the Admiral. She even tells him that If It's You, It's Okay after her second upgrade.
Yamato Nadeshiko: Yamato. Her character itself already presents that aura, and the official 4-koma manga does leave some traces on that.
To a certain degree, Hōshō. Since the real life Hōshō is world's first commissioned ship that was designed and built as an aircraft carrier, many fans depicted her as the mother figure of the game, taking care of admiral's well being.
You Gotta Have Blue Hair: While most of the girls have reasonable hair colors, a good amount (including entire classes) thrive from the technicolor hue of their hair.
Zettai Ryouiki: Shimakaze is the one of the more obvious examples, but other girls (like Kongou and her sisters) also sport this.
