Imperial Japanese Army Vessels

The Imperial Japanese Army never had a good relationship with its naval counterpart. While many armies more or less possess naval vessels to facilitate their operation, it is unlikely that anyone would exceed the level that the IJA had due to its rivalry with the navy, which was very reluctant and hesitant to provide any support to the former, from landings to transport to escort missions. As it became obvious that relying on the navy for protection was unlikely, and doing without one proved to have an extremely high fatality rate, the IJA decided to work around the problem by starting their own naval units.

The lack of know-how and the worsening war draining the remaining resources meant that most of them were barely sea-worthy. However, because of their upbringing, in the game they tend to have unique functions that no IJN ships can perform. The first batch of them were introduced in 24 December 2013 along with the Large Ship Construction features.

     Imperial Japanese Army Vessels 

Akitsu Maru (Landing Craft Carrier/Escort Carrier; Amphibious Assault Ship in-game)

Voiced by: Mamiko Noto

"My name is Akitsu Maru. It is an honour to be part of this fleet."

  • Fanservice Pack: Gets noticeably bustier in her remodeled form, and the remodeled form's "damaged" illustration has some of the most extreme Clothing Damage in the game, with almost her entire shirt and bra destroyed.
  • Genre Savvy: A few of her hourly lines are dedicated to how practically wasteful actually getting her through LSC is.
    Akitsu Maru: 1400. Such a large amount of resources!
    Akitsu Maru: 1500. You could build a battleship with what you used for myself, yes?
    Akitsu Maru: 1600. That was quite reckless Admiral. One such as I is specialised in amphibious operations. Now that you've spent so much I shall have to....what!?
  • Magikarp Power: She cannot even launch planes until she is remodelled. However, she comes with daihatsu-class landing craft that can boost resources gained from expeditions. After remodeling, she also gives Ka-1 and Ki-76, both of which perform decently against submarines.
    • Another note that she can still attack (not launching planes) during shelling phase. Which proven to be useful especially during the AL/MI event.
  • Onmyodo: After remodelling, she gains a scroll as well as the ability to launch plane shikigami. She does have a styling closer to Buddhism compared to Ryuujou and the Hiyou-class' Shinto styling (also by the same artist), what with the Siddham writing all over her scroll...
  • Raven Hair, Ivory Skin/Eerie Pale-Skinned Brunette: Appeared as one with chalk-white skin in unimpressive grey clothes both before and after remodelling. However, she gained a bit more colour from accessories (and a black outfit) after remodeling and her remodeled form's damaged sprite reveals that she has normal-coloured skin, implying that the white skin could be due to make-up. It is speculated to be based on a combination of army camouflage and the grey colouring scheme that warships in the period used. Fanworks sometimes depict the Abyss Fleet mistaking her for one of their own because of this.
  • This Looks Like a Job for Aquaman: Even when remodeled, many players often ignore Akitsumaru due to the fact that she can only carry green (or Combat Air Patrol) planes. However, two events in a row — Summer 2014 (Midway) and Fall 2014 (Operation Kon), whose real-world plans had amphibious landing components — have unusual branching requirements that make her useful on certain maps for providing extra fighter power while sending the fleet on a less random and less battle-intensive path.
  • Verbal Tic: ~ De arimasu, along with how she pronounced "2" (ni instead of futa) in her hourlies. Part and parcel of her militaristic formalities as it is based on Yamaguchi dialect from western Japan, where the IJA found its root and thus became its lingua franca.
  • Zettai Ryouiki: Barely visible in her basic form, and a little less obscure in her remodeled form.

Maruyu (Transport Submarine; simply Submarine in-game)

Voiced by: Mamiko Noto

"Nice to meet you... Maruyu, reporting for duty. Huh? You havenít heard about it? ...Oh no...!"

Maruyu is a Composite Character and personification of the Type 3 submergence transport vehicle. She tries to do her best at everything she does, because she is conscious about the fact that all the other ships look down on her.

  • Composite Character: She is not stated to be based off any particular individual Maruyu.
  • Embarrassing Nickname: She is often called a "Mole" or a variant thereof (since she was used for mole runs, which were covert supply missions done with submarines). She doesn't like it all that much though.
  • Friendless Background: Hinted through some of her lines. Likely due to the fact that, as an Army ship, all the other Kanmusu would look down on her (although in the 4-koma, they avoid her for a different reason, namely trauma from historically being sunk by submarines).
  • Joke Character: She is the "failure" result of the Large Ship Construction system. As a transport submarine, her stats are abysmal, and she is the only ship (as of her introduction) not to have an equipment slot until remodel. However, as modernization material, she can boost a ship's luck, which no other ship currently can.
    • For this reason, Maruyu as a luck boost is actually a desirable outcome of LSC over common battleships/carriers, since anyone experienced and conduct LSC would have abundance of them and have no option other than scrap/modernization on these battleships/carriers.
  • Odd Friendship: With Kiso. According to her hourly lines, Kiso even teaches her to cook curry for herself.
  • School Swimsuit: A white swimsuit with her name painted in red on her chest.
  • Six-Hit-Point Wonder: In a game where even the weakest ships have ~15 HP , Maruyu has six (or seven when she's remodeled), meaning that a single depth charge hit will be able to drain her entire HP. This is only averted by the game mechanics that prevent ship girls from sinking when they did not enter the battlefield at major damage level (and in Maruyu's case, it's only when she has one HP (at least until she's married(temp)), where she literally becomes a One-Hit-Point Wonder).
  • Super Drowning Skills: Implied to have this as she almost drowned herself when taking a bath (repairing at dock), which is pretty impressive given that she was a submarine taking a bath. It is a historical reference to a real Maruyu-class ship sinking during its ceremonial launch, of all things.
    Maruyu: Whew, Iím so tired... Iíll just go take a nice bath and...huh? N-No! I keep on sinking!
  • Verbal Tic: She has a tendency to say "Mogu-mogu", it's another reason why she is often referred to as a mole.

The Kriegsmarine

The naval arm of Axis-era Germany, the Kriegsmarine (literally War Navy) historically focused much of its operations in the Atlantic Ocean, and barring commerce raiding in the Indian Ocean by U-boats of the Monsun Gruppe, had little to no overlap with its allies in the Imperial Japanese Navy.

Three of its ships are the first non-Japanese ship personifications introduced to the game, added during the March 14, 2014 White Day update.
  • Author Appeal: The first batch of Kriegsmarine ships were designed by Humikane Shimada (of Sky Girls, Strike Witches, and Girls und Panzer fame), and as such display a distinct lack of skirts or pants of any kind.
  • Gratuitous German: Sure, they are supposed to be German but, due to lacking voice actors that can speak German well, they speak barely more German than I-8. U-511 even drops most of it after becoming Ro-500.
  • Named After Someone Famous: A great number of their ships, including all three of the first batch of ships.
    • Currently all but one of them are named after someone famous - though not necessarily famous in Germany. Prinz Eugen is named after Prince Eugen of Savoy, a field marshall serving under the Austrian Habsburg Monarchy in the late 17th and early 18th century. As Austria had been annexed into Germany at the time, famous Austrian figures like Eugene were retroactively considered German.
  • Phenotype Stereotype: All but one of them have blue eyes and varying shades of blonde, going from U-511's platinum blonde to Prinz Eugen's medium strawberry blonde.

Destroyers (DD)

    The ZerstŲrer 1934 Class 

The first class of destroyers built by the German navy after World War I, these ships were fraught by design problems by virtue of being built in a hurry. From engines that required excessive levels of maintenance, to limited operating range (half of that of contemporary British Royal Navy destroyers), to limited ammunition stores, it's no wonder that most of the class did not survive to the end of World War II.
  • Born Unlucky: Have the lowest Luck scores of any Destroyer, at least when unremodelled. A reference to the ill-planned way they were designed.
  • Necessary Drawback: Both have above-average durability, three equipment slots from the beginning and a base ASW rating of 69, which is equal to those of both Yuudachi and Shigure Kai 2, and joint-second only to Verniy's 74. However, their other stats are lacking and they have the lowest evasion amongst the Destroyers. In their "zwei" (German ships' equivalent of Kai 2) incarnations, besides a minor upgrade to most stats, their AA stats become second and third only to Shigure Kai 2's.
  • Theme Naming: All named after male Imperial German Navy personnel who were killed in action during World War I. In the case of Z1 and Z3, they shorten these names to something more manageable for the admiral.

Z1 Leberecht Maass

Voiced by: ???

"Guten Morgen. I'm Leberecht Maass. Lebe is fine, yep."

Z1 Leberecht Maass a.k.a. Lebe is the personification of the German destroyer Z1 Leberecht Maass. She particularly dislikes mines, as her historical counterpart ran into and was sunk by mines after having her steering gear knocked out from friendly-fire damage by a Heinkel He 111 bomber.
  • Bokukko: It's hard not to think of her as a little boy from first glance. Her name and speech mannerisms don't help either, leading the IJN destroyers to mistake her for a boy.
  • Born Unlucky: 8 luck when unremodelled, due to the ill-planned way she was designed, as well as how she sank.
  • Boyish Short Hair
  • Culture Blind: If the Admiral pokes her.
    Lebe: "Admiral, what is it? Is this one of this country's greetings? It's going to be difficult until I'm used to it."
  • Face Death with Dignity: If she gets sunk.
    Lebe: I'm sinking, once again, huh. But, this time... it was in a real battle...
  • Feminine Women Can Cook: Played with; her looks and speech patterns aren't very feminine, but in her hourly notification lines she often cooks German dishes for the Admiral.
  • Named After Someone Famous: She is named after Leberecht Maass.
  • Poor Communication Kills: How her historical counterpart was sunk. The Kriegsmarine had failed to notify its destroyers that the Luftwaffe (the German air force) was making anti-shipping patrols at that time and had also failed to inform the Luftwaffe that its destroyers would be at sea.

Z3 Max Schultz

Voiced by: ???

"Guten Tag. I am the Destroyer Max Schultz. But, Max is fine. Pleased to meet you."

Z3 Max Schultz a.k.a. Max is the personification of the German destroyer Z3 Max Schultz. Like Lebe, she also dislikes mines, due to her historical counterpart being sunk by the same mines that may have sank Z1, in the process of trying to rescue survivors from the latter.
  • Born Unlucky: Like Lebe, due to the ill-planned way she was designed, as well as how she sank. However, her unremodelled luck is lower at 6, possibly due to sinking with all hands while Z1 had 60 survivors.
  • Boyish Short Hair: Just like her sistership Leberecht-Maasse, but with longer hair in the front, making it easier to identify her for a girl.
  • Feminine Women Can Cook: Like Lebe, in her hourly notification lines she cooks German dishes for the Admiral.
  • Named After Someone Famous: She is named after Max Schultz.
  • The Stoic: And truly icy at that.

Heavy Cruisers (CA)

    The Admiral Hipper Class 

Prinz Eugen

Voiced by: Ari Ozawa.

"Good morning! I'm the heavy cruiser Prinz Eugen. Nice to meet you!"

Prinz Eugen is the personification of the German cruiser Prinz Eugen.
  • Big Sister Worship: Despite not being an actual sister, she treats Bismarck as if she was one.
  • Blood Knight/Genki Girl: She get's pretty excited when entering battle, cheerfully shouting "FIRE! FIRE!" in German when she attacks.
  • Born Lucky: Contrast to the other German ships who appeared before her, she starts with high luck. Considering she survived the war and tests Able and Baker at Crossroads. She only sank because of damage unrepaired only because she was too radioactive to be able to do so.
  • Dangerously Short Skirt: Which makes her more fully dressed than the other Kriegsmarine ships, because at least she has a skirt. But only barely.
  • Feminine Women Can Cook: Can cook German dishes as stated in her hourly lines.
  • Gender-Blender Name: Perhaps the most glaring case among the Kantai Collection characters, as she is named after an Austrian prince complete with the masculine title. "Eugen" is exactly what it sounds like, the German equivalent to Eugene.
    "I'll just get this out of the way: I'm not a boy."note 
  • Necessary Drawback: Like the other German ships however, she has excellent durability but a lower maxed base AA compared to comparable Heavy Cruisers.
  • Nice Hat: A peaked hat almost identical to Bismarck's.

Battleships (BB)

    The Bismarck Class 

Bismarck

Voiced by: Aya Endo

"Guten Tag. I am Bismarck, the nameship of the Bismarck-class battleships. You should remember it well."

Bismarck is the personification of the German battleship Bismarck. A dutiful and prideful girl.
  • Achilles' Heel: Her rudder.
  • Boisterous Bruiser
  • Boobs of Steel: And she even wears a Breast Plate.
  • Born Unlucky: Initially at least; she starts with below average luck due to being sunk in her first operation. On the other hand, her zwei remodel gives her above average luck, presumably due to her being able to sink the world's largest battlecruiser HMS Hood during said operation.
  • Detached Sleeves: Of course.
  • Lightning Bruiser: Has a listed speed of "Fast", like the Kongou-class. Furthermore, her health when remodeled (94) is third only to the Yamato-class (96 and 97) and second only to Musashi (97) with her zwei and drei remodels (96).
  • Named After Someone Famous: She is named after Otto von Bismarck.
  • Necessary Drawback: To offset her great durability, she has a ridiculously low Anti-Air stat. The Anti-Air stat is later compensated itself in her third remodel with the ability to launch (relatively weak) torpedoes. This reflects her real-life sister ship Tirpitz having been refitted with torpedo tubes. Bismarck in real life was sunk before she could receive this refit.
  • Nice Hat: A Kriegsmarine peaked cap with radar wings on its sides.
  • Phenotype Stereotype: Played straight, as she's drawn as tall, blonde, and busty.
    • Historical In-Joke: The above trope is played even straighter when you realize that this is supposed to reference Hitler's requirements for being part of the Master Race, which is the Aryan race (blonde, blue-eyed, and "pure" German). In fact, the only thing Hitler may have been iffy about is the fact Bismarck here is also a girl (at least her commanding officer, Capt. Ernst Lindemann would), but she's otherwise the perfect representation of what Nazi Germany truly wanted.
  • Vanity Is Feminine: She talks in a feminine way and takes care of her appearance.
  • Weaksauce Weakness: For a battleship, Bismarck has a ridiculously low Anti-Air score. To give you an idea of how low it is, Akigumo, a destroyer, has a higher AA score than her, at least until her zwei form, and even then Z1 and Z3's zwei forms, generally regarded as relatively weak destroyers, have better AA than hers. The real-life Bismarck did indeed have unimpressive anti-aircraft armament, and was also crippled in a torpedo attack by hopelessly obsolete biplanes.
  • Zettai Ryouiki: A grey pair.

Submarines (SS)

    U-Boot Type IXC 

U-511/Ro-500

Voiced by: Ai Kayano

"Submarine U-511 of the German Navy, please call me Yuu. I've come a long way, so I'll be in your care..."
"Submarine Ro-500, formerly U-boat U-511. I'm Ro, formerly called Yuu! Admiral? I will be in your care."

U-511, a.k.a. Yuu, is the personification of the German Submarine U-511. Originally a stoic girl who is trying to adapt to her new surroundings, her second remodeling turns her into Ro-500 or simply Ro, a cheerful girl who reflects the name change she received once she was transferred to Japan.
  • Animal Motif: A wolf pup. Her initial uniform's radio headset resembles dog ears, and when remodeled, she sometimes growls like a "little wolf".
  • Ascended Meme: One of her hourly lines has her asking if she's going to visit Orel or Bashi.Explanation 
  • Born Lucky: Indeed, she had to travel from France to Japan, and she survived the war.
  • Character Development: As U-511, she's very quiet and shy, and struggles with her Japanese a bit. Once she's remodeled to Ro-500, representing adapting to her new home, her Japanese is fluent, her personality is much more cheerful and outgoing, and she seems to have become very good friends with the other submarines.
  • I Have Many Names: Is referred to "Yuu" or simply "U" as U-511, Satsuki #1* About the name  as an alternate name when remodeled, and "Ro" or "Ro-chan" as Ro-500.
  • Flower in Her Hair: As Ro-500.
  • Going Native: Her transformation into Ro-500 is heavily implied to be this.
  • I'm Cold... So Cold...: If she gets sunk as Ro-500.
    Ro-500: No... Nooo... It's cold... So cold... And dark...
  • Nice Hat: As U-511, a garrison cap with a radio headset that looks like a dog's ears.
  • School Swimsuit: Exchanges her uniform for the requisite swimsuit of the Japanese sub-girls with the addition of a cropped German-style sailor uniform (similar to Z1 and Z3) as Ro-500.
  • You Don't Look Like You: Her design and personality suddenly change after her conversion, from being an unemotional pale girl in a uniform-like wet suit to a cheerful girl with a tan who looks far more like her Japanese submarine peers (but without denying her actual roots).
  • Verbal Tic: She tends to end her sentences with "-tte", which is mainly used as a form of Japanese case-making particle.

Regia Marina

The naval arm of the Kingdom of Italy, who were allies of Germany during the Second World War, the majority of the Regia Marina's operations were centered in the Mediterranean Sea, which Mussolini infamously declared "Mare Nostrum" (literally "Our Sea"). It had limited operations in the Atlantic, the Middle East, and the Baltic, before Italy eventually surrendered to the Allies in 1943.

The first Italian ships were added on April 2015, during the 2nd-Year Anniversary of the game, as rewards for the Spring 2015 event.
  • Author Appeal: Jiji, the artist who drew both Littorio and Roma, is a regular contributor of lolicon or mecha musume art, but when he does draw adult women, he draws them busty and plump. He also has a thing for Mami Tomoe of Madoka Magica fame, who Littorio oddly reminds people of...
  • Gratuitous Italian: Thankfully averted. They speak very few Italian and the little they say usually makes sense considering the context they are used.
  • In-Series Nickname: "Land of the pasta" (パスタの国; lit. pasta country) for Italy, in the description of the Italian equipment and in Littorio/Italia's library intro line. As a result, the Italian equipment and the Vittorio Venetto class have been given the Fan Nicknames of Pasta equipment and Pasta BBs respectively.

Battleships (BB)

    The Vittorio Venetto Class 

Built as a response to the French-made Dunkerque-class of battleships, the ships of the class were some of the most modern for their time. Unfortunately for them, their tours of duty were cut short at the capitulation of Italy to the allies.

  • Awesome but Impractical : The 381mm / 50 Triple Gun Mount, which was initially available as one of March 2015 ranking rewards, and are the default equipment of the Littorio-class battleships, are regarded as this, as it is very powerfulExplanation  and long-ranged for it's modestly-sized 381mm caliber. However, the guns itself comes with a significant loss of accuracy and slight reduction of evasion despite being less than 16 inch (40.6cm in metrics) in caliber, making it all the more impractical in the Combined Fleet due to the huge accuracy penalty imposed for mobilizing such a massive fleet means that this already inaccurate gun are unlikely to hit enemy ships with reliable accuracy. Since there are no in-game restrictions up to 46cm for the caliber size of the main guns for fast battleships, many players has regarded it as a joke armament and opted to replaced the stock Italian BB guns with more accurate guns. The gun itself is upgradeable into its Kai version, fortunately, though the gun remained somewhat inaccurateExplanation .
    • This is pretty much what the Italian 381mm guns were like in real life, firing very high-velocity shells (muzzle velocity of 870 meters per second, a good 50 m/s faster than the Bismarck's guns and indeed faster than any other battleship's main guns of any size) which resulted in a theoretical maximum range on par with the Japanese 46 cm guns, but also resulted in excessive barrel wear and poor accuracy.
  • Detached Sleeves: Shared by both sister ships.
  • Lightning Bruiser: True to their historical counterpart, they are classified as fast battleships and they have both excellent firepowerExplanation  and durability as well as decent AA.
  • Necessary Drawback: In exchange for such an impressive firepower, range and speed, they are fairly resource intensive to maintain, having a much higher fuel and ammo consumption rate than the Nagato-class battleships. They also requires a blueprint for their (single) remodel as well.
  • Nice Hat: Technically a diadem, which is shaped like the bow decoration of the ships they are based on.
  • Of Corsets Sexy: And used to accentuate the Littorio class' impressive... fuel tanks.
  • Vocal Dissonance: Despite being battleships, Littorio and Roma have very high-pitched voices, in the same range as the higher-pitched destroyers.
  • Zettai Ryouiki: Both Littorio and Roma wear a partially stripe-patterned pair.


Littorio/Italia

  • Born Lucky: She starts with above average luck due to having survived the war.
  • Please Select New Ship Name: She was originally named after the Lictor, which were symbolized with the fasces. As the fasces was a symbol and namesake of fascism, when Mussolini was kicked out of power, she had to be renamed to something else, thus "Italia".
  • Supreme Chef: Strongly implied to be this with all food she cooks.

Roma

  • Born Unlucky: She's the first major warship to be sunk by a guided bomb attack after one of the Fritz-X radio guided bombs launched by the Germans struck one of her magazines. The force of the explosion was so powerful it blew her number 2 turret clear off of it's mountings off the ship, which is why her damaged artwork is missing a turret.
  • Don't Look at Me!: She seems to hate being stared at as her quotes seem to indicate.
    Roma: I'm going to need a little repair. What? Don't stare at me.
  • Meganekko: A round-framed pair.
  • Rare Random Drop: Unlike her sister, who was a reward for clearing map E4 of the Spring 2015 event, Roma can only be obtained as a random drop after getting an S rank on the boss node of E6 (or on a node along the way, for a much lower chance) for the same event.
    • She's such a rare drop that many frustrated admirals have declared that Roma is a myth. After often more than a hundred runs, many admirals have also spent a multitude looking for her than they did on the entire event combined. If you hardly had any resources left to begin with, the hunt for Roma gets all the more difficult since you also have to carefully manage your resources and are often forced to pause to let your resources recover a bit which costs valuable time.

Event-exclusive ships

The Fleet of Fog

During the Fall 2013 Anime season, the anime Arpeggio of Blue Steel aired, coinciding with much of Kantai Collection's rapid rise in popularity and recognition. Naturally, a collaboration between the two franchises was inevitable. It started with a few endcards in the anime with some Arpeggio ships paired with their KanColle counterparts, and culminated in a crossover event in the KanColle game running from 24 December 2013 to 8 January 2014. During this time, certain ships from the Fleet of Fog were usable as temporary allied units, which were removed when the event ended.

All ships of the Fleet of Fog retained their anime voices, had hourly lines, and could not be remodelled. The ship library did not include them either. They also retained their personalities, and a number of their lines were references to the anime (although there was no mention of Gunzou).

For the tropes depicting the Fleet of Fog in the Arpeggio anime, please see here.
  • Big Eater: In fanon, considering the massive amounts of resources required to resupply and repair them, even more so than the likes of Yamato and Musashi (although that's only because they're used a lot more frequently; the Yamato-class ships actually cost more to fully repair or resupply). Commonly attributed to the nanomaterials.
  • Born Lucky: At least, they get higher starting luck than their KanColle counterparts, but their maximum luck is lower as well (except for Iona). In particular, Iona's starting luck was 50, which was equal to Yukikaze's. Then again, it capped at a relatively average level (59) if you fed her with Maruyu (not that you'd be likely to).
  • Guest Star Party Member: At least they averted So Long, and Thanks for All the Gear.
  • Lightning Bruiser: With the exception of Anti-Air and Evasion for Takao and Haruna, all of them had much higher stats than their KanColle counterparts (including a longer range), and all had a listed speed of Fast. Iona is a particular case, because as a submarine the damage she took was already naturally reduced, and all the KanColle submarines (including her KanColle counterpart, I-401) have a listed speed of Slow, and nowhere near the giant HP pool (by submarine standards) that she had.
  • Necessary Drawback: Their soft stats never increased regardless of level. For Takao and Haruna, they also had the Graviton Cannon in exchange for reduced Anti-Air and evasion. Takao also got only 3 equipment slots (a remodelled heavy cruiser has 4). These, coupled with their high consumption, are pretty much the only drawbacks they have. In addition, when it came to recon seaplanes, their slot size was 0. This did not affect much when they were around (in fact Iona couldn't carry seaplanes anyway), but if they were in the game now, they would be unable to conduct artillery spotting.
  • No Sell: The Klein Field, at least in theory. In practice, they were just fancy miss animations. And unlike the anime where the Klein Fields were all of different colours, every Fog ship's Klein Field in the game (both enemies and allies) was pink.
  • Target Spotter: Again, they all started with high Line of Sight, far exceeding that of equivalent ship classes in KanColle (except for Tone-class heavy cruisers' LOS beating Fog Takao's, and even then only at high levels).
  • Wave Motion Gun: Except Iona.

    The Fleet of Fog 

Iona

"Submarine I-401, Iona. Crash dive~"

The Fog ship obtained from completing the event-exclusive quest which also unlocked Event Map 1 (E1), Iona was arguably the most useful of the usable trio, both in event maps and in normal maps. As a Fast submarine with incredibly high HP (70 to be exact), her uses outside of the event maps included submarine cheesing for map clearing and farming purposes, being used to avoid the submarine node in 5-3 as well as to draw enemy attacks (due to being a Fast submarine), and completing the submarine fleet composition quests. Due to being a submarine, she also repaired very fast, and consumed the least resources of the three (although still a lot by this game's standards).
  • Catch Phrase: Crash dive~ (急速せんこ~, Kyuusoku senko~). Contrast the anime, where she said the line only once (in episode 1), and nowhere in the same cutesy tone as in here.
  • Flight, Strength, Heart: So Iona had a high Torpedo stat, high Armor, high Luck, high Line of Sight, fast Speed, high HP, some Anti-Air... wait, what was she doing with long Range and high Firepower, again?
  • Hates Being Alone: Her idle line.
    Iona: Where are you, Admiral? I don't want to go back to that dark dock. I hate being alone.
  • Lampshade Hanging: Poking her would make her lampshade the rarity of Submarines (although with 1-5 coming out some time after the Arpeggio event ended, this may no longer be the case).
    Iona: Are submarines that rare for you, Admiral? When it's just the two of us, why do you want to look at my stomach?
  • Sorry That I'm Dying: If she got sunk, although you really had to be trying for it to happen.
    Iona: Sorry... I wanted to fight with you to the very end, but I can't surface anymore... Farewell, Admiral.

Takao

"Heavy Cruiser Takao, launching! All those who would call me the 'Tsundere Heavy Crusier', get out of here now!"

The Fog ship which first appeared as a boss in E1. Upon defeat she disappeared from the boss node and became available as a usable unit upon completing the quest which unlocked E2, in the same manner as Iona. As a heavy cruiser, one of her most notable uses outside of the event maps was manipulating the compass to clear maps like 4-4 efficiently.
  • Can Not Spit It Out: One of her hourly lines.
    Takao: "Erm.. Admiral? If you're going to take a siesta you can use my... my... la... It's too embarrassing to say!"
  • Determinator: Her line when heavily damaged.
    Takao: "Love... will never sink!"
  • Tsundere: Natch, with a classic tsundere line to boot. She even knew of her fame as the "Tsundere Heavy Cruiser", as shown in her introductory line and the quest to find her.
    Takao: Don't misunderstand me! It's not like I'm fighting for you or anything!
  • Weaksauce Weakness: Her E-1 boss form couldn't touch subs so the easy way to beat her was to just send subs against her.

Haruna

"Battleship Haruna.... is here."

The Fog ship which first appeared as the E2 boss. Similarly to Takao, she disappeared on defeat and was obtained together with access to E3. As a battleship, she consumed the most resources of the three (repairing her to full took over 1000 steel; thankfully she still consumed less than the Yamato-class, though one can only wonder just how much resources the Fog Yamato-class would consume). However, as a battleship, she also hit really hard (in fact, she is to date still the only ship that can exceed the maximum firepower soft cap for day battles even in red T engagement). A notable use outside of the event maps was for getting a second shelling phase to clear maps more easily.
  • Badass Longcoat: As in the anime. Interestingly enough, getting heavily damaged would make her lose her coat, although repairing her somehow let her get it back.
  • Cry Cute: If repaired while heavily damaged. Also one of her hourly lines where she had to take a bath.
  • The Stoic: Most of the time, except her Cry Cute moments.
