Ika Musume/Squid Girl

http://static.tvtropes.org/pmwiki/pub/images/squidgirl_8810.jpg

Voiced by: Hisako Kanemoto (Japanese), Christine Marie Cabanos (English, Media Blasters dub), Alice Beaver (English, Animax dub)

The "protagonist" of the series, an anthropomorphic squid-girl who comes ashore to invade the surface world in retaliation for constant human pollution of the seas, only to end up being forced to work as a waitress at the Lemon Beach House restaurant in order to pay for a damaged wall of the restaurant.
  • Adorkable: Oh so much. Her being a Fish out of Water gives her an adorable child-like naiveté about many different aspects and items of life on the surface.
  • Alien Hair: Has tentacle-hair that she can control.
  • Anti-Villain: Technically a Well-Intentioned Extremist (Type III), but her traits are more akin to a Villain In Name Only (Type IV).
  • Applied Phlebotinum: In Season 2 episode 2.3 it turns out that Ika Musume can pick up heavy weights with her tentacles because she can manipulate her weight using her bracelets.
  • Badass Adorable: Her silly antics make it hard to forget but those tentacles are capable of busting holes in walls... which is actually the reason she works at the Lemon Beach House in the first place.
  • Between My Legs: The shot used when she's introduced. The same introduction shot is used in the first and last episodes of both seasons. She also gets this shot in episodes 3 and 7.
  • Brilliant, but Lazy: She's shown to be extremely good at math, has mastered several skills that have nothing to do with world domination, and of course there's her extremely powerful tentacles. She could at least be a serious threat, if she wasn't so lazy and easily distracted (and of course, if it weren't for Chizuru.)
  • Card-Carrying Villain
  • Cold Turkeys Are Everywhere: After she swears off shrimp. They pop up everywhere.
  • Combat Tentacles: They are absurdly strong, faster than sound, can reach ludicrous lengths but are also precise to put a string into a needle. And they can regenerate just as fast.
  • Comically Missing the Point: Due to being a literal Fish out of Water, she barely knows anything about the surface, and tends to misinterpret a lot of things.
  • Cry Cute: Every time Chizuru intimidates her into obeying her, or whenever a "comrade" of hers (e.g. Takeru in a squid paper-hat and an umbrella) "dies" (Takeru's hat blown away, the umbrella ran over by a truck).
  • Curtains Match the Window: And the tentacles.
  • Cute Clumsy Girl: Without the use of her tentacles she can barely kick a soccer ball.
  • Cute Monster Girl: A cute squid girl.
  • Dark and Troubled Past: Occassionally hinted at. It seems life in the ocean wasn't all that great for her. When Eiko mentions how Ika isn't picky at eating, she responds by saying in the ocean you can't afford to be picky, just being able to eat at all is reason to be happy. She later tells Takeru she had never had the opportunity to play with others until she came to the surface. She seems oddly depressed when these subjects are brought up.
  • Even the Girls Want Her: Ika is, in an appropriate and friendly way, friends with many kids of either gender, specifically Takeru and Kiyomi's respective groups of friends. Sanae and Cindy, on the other hand...
    • In season 2 episode 9.1, Ika is asked by a little girl named Risa to join her play as her husband. Minutes later, Eiko, Sanae, and Kiyomi all join in. They have different roles but they share one similar thing: they LOVE Ika Musume. They even take their roles seriously and act as though they are genuinely in love with her.
  • Face Your Fears: In Season 2, Episode 11.3, she overcomes her fear of Chizuru, accidentally ticks her off again, and gets dragged by her to a room while showing NO signs of fear.
    Ika: Oh? About what? (while being dragged by Chizuru to a room)
  • Fish out of Water: It's what the show's about!
  • Genius Ditz/Small Name, Big Ego: At her best, she is the former. At her worst, she is the latter.
  • Genki Girl: Extremely excitable.
  • Godiva Hair: Ika has this when she's in the bath.
  • Heel–Face Turn: Not completely so, but it does happen as the series progresses.
  • Humans Are the Real Monsters: Her reason for invading the surface world. Her subsequent experiences, however, apparently start to impress to her that the situation is more like "Humans Are Flawed".
  • Hurricane of Puns: The dub version makes many puns related to undersea creatures. This is to match the original Japanese version's way of matching punnery in which she would emphasize the ika ("squid") in any phrase containing it (for instance, with -ja nai ka ["isn't it ____?"], with emphasis normally on the nai, would be pronounced -jana-ika).
  • I Call It "Vera": Her umbrella.
  • Iconic Outfit: Her cute white tunic with blue bracelets and matching shoes. So much so, that they have the ability to repair itself.
  • Ineffectual Sympathetic Villain: Ika Musume has Combat Tentacles and a strong desire to conquer the human race. She has a bit of trouble getting to the conquering part however.
  • Instant Expert: She's able to speak fluent English after a short lesson from Cindy.
  • Jerk with a Heart of Gold: Underneath all of her rudeness she really is a good person.
  • Laser-Guided Amnesia: In Season 2, Episode 7.2.
  • Light 'em Up: Like certain types of squid, she can emit light from her body.
  • Modern Major General:
    Ika: "Why am I good at everything but invading?"
  • Multi-Armed Multitasking: Her tentacle-hair.
  • Mundane Object Amazement: Given her little knowledge of the human world, this naturally comes in.
  • Mundane Utility: Her Prehensile Hair is frequently used like an extra set of hands for carrying food.
    • In fact, this is why she's given the job at the restaurant. Her delicious ink also helps.
  • Never Bareheaded: And for a very good reason: it's mentioned that her "hat" is actually her life source. If it's removed, she dies. Luckily, removing it is pretty hard since it's fused to her scalp. Since she's a squid, it may actually be her scalp (it certainly looks like the top of a squid's head).
  • Nice Hat: It's more than just a Nice Hat, she needs it to live.
  • No Social Skills: Due to having lived in the sea before going up to the surface, this is a given.
    Ika: "What's a military?"
  • Offhand Backhand: To Sanae, every time she tries to glomp her.
  • Parasol of Pain: In her imagination at least.
  • Prehensile Hair: While not actually hair, Ika Musume has highly prehensile tentacles growing out of her head, which look quite a bit like hair.
  • Pungeon Master: In the dub, where she gets kraken with a bunch of fish puns instead of her verbal tic.
  • Required Secondary Powers: It's eventually explained that the whole reason Squid Girl can pick up people and other heavy objects with her tentacles without losing her balance is that she can alter her weight with her bracelets, becoming heavy enough to anchor herself.
  • Red Eyes, Take Warning: She does this in the anime when she gets angry and unleashes her full power. Watch a brief example here.
  • Sick Episode: Ika falls ill to a Squid Girl disease. Symptoms include nausea, headaches, flushes in the face, fever, delirium, and death...ly cravings for shrimp.
    • Again in Season 2 episode 8.3. Unlike in the first season, she appears to have a normal fever which she gets from Kiyomi.
  • Sitcom Archnemesis: Sometimes sees Goro as one.
  • Take Over the World: Her ultimate goal. Too bad she has no idea as to the strength of all the world's military forces.
  • Tentacle Rope: In one instance, Ika does this to Eiko when she wanders into Eiko's room and falls asleep there... Rather, her tentacles did this all on their own. Ika herself was already long asleep.
    • Ika also does this as a self defense mechanism against Sanae and Cindy.
  • Trademark Favorite Food: Shrimp. She has a separate stomach for it.
  • Tsundere: A type A.
  • Unusually Uninteresting Sight: No one save Nagisa ever takes notice of her strange appearance and Prehensile Hair.
  • Unwanted Harem: Eiko and Isozaki come to realize this. Maybe not a true harem, but definitely unwanted.
  • Verbal Tic: -de geso~. The English version of the anime translates this into frequent ocean life puns, apparently as an Ascended Meme from the fansubs.
  • Villain Protagonist: Ika wants to take over the world because humans have been polluting the seas.
  • Vitriolic Best Friends: With Eiko. They bicker a lot, but sure do spend a lot of time together as well, and Ika plays Eiko's video games a lot as well.
  • Why Did It Have to Be Snakes?: Afraid of Chizuru's eyes, orcas and sharks. Those last two are Truth in Television, as orcas and sharks eat squids.
    • After the end of Season 2, Episode 11.3, it looks like Ika is not afraid of Chizuru anymore, even if she accidentally ticks her off again and gets dragged by her to a room.
  • Woman in White: Has a white dress.
  • Work Off the Debt: Her "Punishment" for blasting a hole in the Lemon Beach House's wall.
  • You Gotta Have Blue Hair: Has blue hair-like tentacles.

    Eiko Aizawa 

Eiko Aizawa

http://static.tvtropes.org/pmwiki/pub/images/eiko_8499.jpg

Voiced by: Ayumi Fujimura (Japanese), Heather Pennington (English Media Blasters dub), Jessica de Borja (English, Animax dub)

Middle of the Aizawa siblings and manager of the Lemon Beach House, as well as Ika Musume's principal "handler".
  • Bodyguard Babes: She's like this towards Ayumi when she sees some Casanova Wannabes try to flirt with her. She almost breaks one of those guys' arms off. Here's a quote from the same guy:
    "Pain in the ass bodyguard!"
  • Book Dumb: Studying isn't her forte, but she's also too proud to ask Ika for help.
  • Cool Big Sis: For Takeru, obviously, but also for Ika, some of the time.
  • Companion Cube: She refers to her Famicom as her buddy since elementary school. When it broke, she was so saddened she buried it in the garden.
  • Deadpan Snarker: To Ika. The latter's lack of knowledge of the surface world and almost never acting like an invader gives Eiko plenty of material to work with.
  • Fiery Redhead: Quite short-tempered, particularly to Ika.
  • Gamer Chick: Keeps a Famicom lookalike inside her room (in the anime it's a Mega Drive lookalike). Oftentimes Ika is her playmate. She even says that gaming is her life!
  • Jerk with a Heart of Gold: She's not a jerk per se, but given Ika's behavior, can we really blame her for sometimes being abrasive towards her?
  • Only Sane Man: Narrative-wise. She's also the person Ika interacts with the most.
  • Red Oni, Blue Oni: Red to Chizuru's blue.
  • Sailor Fuku: Her high-school uniform.
  • Seen It All: Is unimpressed by Ika's grandstanding (until Ika proves she's really a squid) because she's met a lot of similarly rambunctious children during her job.
  • Vitriolic Best Friends: With Ika/Squid Girl. Despite the arguments they get in, they spend a lot of time together. Chizuru once lampshaded it, saying Ika and Eiko fight so often that one could say they're very close.

    Chizuru Aizawa 

Chizuru Aizawa

http://static.tvtropes.org/pmwiki/pub/images/chizuru_charimage_707.jpg

Voiced by: Rie Tanaka (Japanese), Shelby Lindley (English, Media Blasters dub), Sarah Hauser (English, Animax dub)

Eldest of the Aizawa siblings, and the cook for the Lemon Beach House. She's a cute, kind and reliable girl, but you do not want to make her angry.
  • A Day in the Limelight: Season 2, Episode 11.3 focuses on her and her quality time with Ika.
    • This is the first and only episode that is focused on her for this season.
  • Badass Adorable: She's moe when not Staring Down Cthulhu.
  • Berserk Button: Her store and her siblings.
    • She has another one, as revealed in Season 2, Episode 11.3: DO NOT EVER IMPLY THAT SHE'S INHUMAN!!!
  • Beware the Nice Ones: Even Eiko is wary whenever she exudes an intimidating aura.
  • Big Brother Instinct:
    • Do not threaten her siblings. Ika discovered this the hard way, and earned an everlasting fear of her ever since.
    • Also Played for Laughs a few other times; the Aizawa siblings care a lot about each other, but this sometimes causes her and Eiko to get a little too worried about their little brother.
  • Cool Big Sis: To both Eiko and Takeru.
  • Creepy Blue Eyes/Icy Blue Eyes: Has blue eyes, which Ika fears, and for a good reason.
  • Curb-Stomp Battle: And she's always on the winning side.
  • The Dreaded: To Ika, who is deathly scared of her anger and eyes.
  • Eyes Always Shut: Well, not completely shut, but she still squints them enough (to make up for her poor eyesight) for the trope to count. And when she opens them, expect a person or two cowering in fear. Though she actually looks pretty good when she opens them without malicious intent.
  • Face of a Thug: In a way, and towards Ika only. Ika is so scared of her that she can misinterpret Chizuru's genuinely kind smiles and actions for glares and incoming torture. For example, when Chizuru easily allowed Ika to sleep on her Lap Pillow, she was being genuinely nice; Ika simply got too scared when Chizuru attempted to clean Ika's ear.
  • The Gadfly: Sometimes she does things because it might be fun.
  • Mentor Archetype: Teaches Ayumi the art of self-defense while having Goro as her punching bag.
  • Meta Girl: Quite possibly, being the only character of the series to acknowledge the three-hundredth chapter of the manga.
  • Ms. Fanservice: While wearing a one piece swimsuit, even, much to the delight of Goro.
  • Nice Girl: Her default state. Annoy her and she'll make you regret it for the rest of your life.
  • Nightmare Face: Almost every time her eyes are open.
  • Oblivious to Love: For Goro. Though she may be aware of what he feels for her and uses it to her advantage.
  • Oh, Crap!: The reaction she elicits from anyone who chances upon her scarier side.
  • Physical God: She's human all right, but some of the stuff she does really makes you wonder:
    • Ika-chan's tentacles are supersonic and can punch through foot-thick concrete; Chizuru can chop said tentacles in mid-flight with her bare hands.
    • In chapter 366, the Three Stooges made a ray gun that causes everyone hit by it to carelessly drop things they're normally careful about. When Ika was affected, she dropped the dishes that she was cautious with. Chizuru holds herself from dropping lightning whenever Ika breaks dishes, so when Chizuru got affected, lightning did come crashing down, to her sister and Ika's shock. She uses the pencil one last time to fry the Stooges with another lightning bolt before handing it back to them, and they lampshade it all as the chapter ends:
    Clark: My ray gun shouldn't have the ability to change the wheather though...''
    Harris: Chizuru Aizawa is unscientific.
    • In chapter 153, she sometimes leaves huge and perfectly round holes in the kitchen's wall without realizing it. Eiko and Ika teamed up with the Three Stooges to find out how: when a mosquito lands on the wall, Chizuru punches it to oblivion so fast, it couldn't be picked up by a camera that slowed the action down to a tenth of a second. As for why the resulting holes are so perfectly round, they never found out.
    • In another chapter, a tetrapod (which usually weighs around a ton) that Ika somehow brought to the Lemon overnight is accidentally enlarged by the Three Stooges, who were trying to get rid of it. Chizuru is the one who ends up removing it, by smashing it to pieces with her bare hands,in a fear-induced adrenaline rush caused by an enlarged bug. Granted, her knuckles were slightly bruised afterwards, but that's still nuts.
  • Red Oni, Blue Oni: Blue to Eiko's red.
  • Super Reflexes: She is rather agile, and effortlessly dodges Ika's tentacle attacks.
  • Tranquil Fury: She never raises her voice when she's pissed: all she has to do is open her eyes and everyone around her starts groveling.
  • Weight Woe: Her only weakness. Ika may have a chance of actually beating her using only this weakness, if she's smart enough to notice it.
    • She is also concerned with her muscles, as Eiko exploits it in an attempt to eat more meat.
  • You Gotta Have Blue Hair

    Takeru Aizawa 

Takeru Aizawa

http://static.tvtropes.org/pmwiki/pub/images/shinryaku__takeru_aizawa_3776.jpg

Voiced by: Miki Ootani (Japanese), Amanda Céline Miller (English, Media Blasters dub), Jessica de Borja (English, Animax dub)

Youngest of the Aizawa siblings.
  • Anime Hair: Has unrealistically spiky hair.
  • Crossdressing Voice: If you look at his portrayers' names above, then yes.
  • The Generic Guy: Lampshaded when Squid Girl tries to draw the Aizawas using her tentacles (which she explains goes by her mental images of them.) Chizuru gets drawn as an oni, Eiko as a killer robot, and Takeru...is a more photorealistic version of himself.
  • Made of Iron: His very first appearance has him getting thrown around and slammed into the ground by Squid Girl's tentacles, only to get right back up and proclaim "That was so cool!"
  • Not So Above It All: Despite treating Ika like a playmate most of the time, Eiko notices that he's slowly learning to subconsciously control Ika — which is easy enough, given her immense gullibility.
  • Out of Focus: In Season 2 Episode 10.1, Ika, Eiko, and Chizuru all forget about him while they try to eat as many cuts of meat as they can. Luckily, Chizuru has reserved some cuts (which she intends to eat herself) for him.

    Sanae Nagatsuki 

Sanae Nagatsuki

http://static.tvtropes.org/pmwiki/pub/images/shinryaku__sanae_nagatsuki_7281.jpg

Voiced by: Kanae Ito (Japanese), Xanthe Huynh (English, Media Blasters dub)

Eiko's neighborhood friend who has taken an obsessive liking to Ika.
  • Abhorrent Admirer: Well, she's actually cute, but this is how Ika sees her.
  • Berserk Button: She is not an alien. Do not forget that.
  • Camera Fiend: She takes a lot of pictures with them. She especially likes taking pics of Ika.
  • Clingy Jealous Girl: The mere sight of Ika having a friendly chitchat with Kiyomi and her friends made her exude a dark aura that made a chill run down Eiko's spine.
  • Cosplay Otaku Girl: She likes cosplaying herself, but she especially loves having Ika cosplay in other outfits.
  • The Ditz: She's no moron, but she's no so bright either.
  • Everyone Has Standards: Despite Ika Musume's fears, Sanae won't take advantage of Ika when she's helpless from heatstroke.
  • Genki Girl: Almost even more so than Ika.
  • The Glomp: Subverted; she tries, only to get back-tentacled by Ika.
  • Hopeless Suitor: To Ika.
  • Lethal Chef: Bless her heart, she genuinely tries to make good food to win Ika's heart, but she's terrible at cooking. Her attempts at it all ended in smashing failure, some of which are the subject of a few chapters:
    • When she tried to concoct a new menu for the Lemon Beach House as part of Chizuru's contest, she ended up making a giant shrimp-shaped dish: it turned out extremely spicy since she used nothing but peppers to make it.
    • In chapter 285, she tries to make a tray of homemade cookies to get closer to Ika. Long story short, they ended up looking, smelling and tasting so awful that they exuded a menacing aura. When Kiyomi tastes one, she claims they're nice so as to protect Sanae's feelings, but her facial expression betrays the truth. Then Ika tries to taste one too, causing Kiyomi to grab the entire bag and eat it in one fell swoop to protect Sanae's feelings further; the taste causes Kiyomi's glasses to shatter and the poor girl to faint.
    • In chapter 383 Sanae asks Chizuru for training to make her cooking better. It still comes out tasting bad, so Chizuru decides what she needs is discipline, putting her through Training from Hell. At the end of it, she's able to break fifteen tiles with a punch (wondering what on earth this has to do with cooking), and tries cooking again. Unfortunately, we don't get to find out if she improved, because she reflexively breaks the table with a punch.
  • Lipstick Lesbian: Is highly gay for Ika, and not afraid to show it.
  • Love Makes You Crazy: Turned Up to Eleven in Season 1, Episode 10 part 2, when she tries to abstain from contact with Ika Musume. She begins to hallucinate Ika Musume is everywhere and everything; a little girl, a set of trash bags, even as the heads of lanterns.
  • No Sense of Personal Space: The main reason why Ika dislikes her.
  • Single-Target Sexuality: She's Camp Ikasexual.
  • Stalking Is Love: To IKA.
  • Super Reflexes: Shows this in OVA 1.2, when she rushes to the Lemon shop to take pictures of Ika, while also simultaneously dodging all of the latter's tentacle attacks.
  • Too Kinky to Torture: Or at least willing to get beaten up by Ika.
  • Yandere: She looks like this whenever she sees Ika chatting with another girl.

    Cindy Campbell 

Cindy Campbell

http://static.tvtropes.org/pmwiki/pub/images/shinryaku__cindy_campbell_9906.jpg

Voiced by: Hitomi Nabatame (Japanese), Laura Post (English, Media Blasters dub)

An American alien researcher who comes to Japan to investigate Ika.
  • Alliterative Name: Cindy Campbell.
  • Anime Accent Absence: In her introduction Eiko tried to speak in English with her (she tried and failed epically) until she revealed she could speak fluent Japanese.
    • She was so fluent in Japanese she eventually discovered, much to her horror, that she speaks English with a Japanese accent.
    • The accent is gone as of Season 2's 4.1, where she spends the whole segment speaking Surprisingly Good English.
  • Eagleland
  • Foreign Fanservice: A sexy blonde woman with a pony-tail, wearing a parka over a two-piece bikini or a tube-top and short shorts? Yes, please.
  • Hot Scientist: A scientist, and very pretty.
  • Mad Scientist
  • Phenotype Stereotype: Blond and well-endowed.
  • Single-Target Sexuality: Her obsession with Ika sometimes goes beyond finding her "alien heritage" and she's heading right in Sanae's direction.
  • Too Kinky to Torture: Much like Sanae, she doesn't mind being on the blunt end of Ika's tentacles.
  • Walking Swimsuit Scene: Is almost always seen in her swimsuit.

Voiced by: Azusa Enoki (Japanese), Cristina Valenzuela (English, Media Blasters dub), Jessica de Borja (English, Animax dub)

A surfer and part-time worker for Lemon Beach House, and perhaps the only person who sees Ika as a genuine threat to humanity.

    Aiko Saito 

Aiko Saito

Voiced by: Hiroko Ushida (Japanese)

An elementary school teacher, and Nagisa's older sister. She's very kind towards her students, but is extremely jealous of Ika, who stole her popularity with the kids.
  • Can't Hold Her Liquor: Downplayed: she can drink a fair amount more than usual for the trope, but her sister still notes she doesn't need a lot of alcohol to get smashed.
  • The Rival: Sees Ika as this, for having "stolen" her popularity with the kids.
  • Sensei-chan: Young, beautiful, and at times surprisingly immature for a teacher.

    Ayumi Tokita 

Ayumi Tokita

http://static.tvtropes.org/pmwiki/pub/images/shinryaku__ayumi_tokita_2250.jpg

Voiced by: Ayako Kawasumi (Japanese), Sarah Williams (English, Media Blasters dub)

Daughter of the manager of Southern Winds, Lemon Beach House's rival restaurant from a neighboring town. She sometimes works part-time at the Lemon Beach House.
  • Antenna Hair
  • Beautiful All Along: Without those creepy "Fake Ika Musume" kigurumi masks her father has her wear.
  • Beware the Nice Ones: After episode 10.2, you better show some manners while talking to her, as her father finds out after she throws him down. Though that one is an accident. She learns self-defense from Chizuru. Yes, that CHIZURU!
  • Bodyguard Crush: While very subtle, it's implied that she may be this for Eiko as she tends to be very shy and bashful towards her.
  • Defrosting Ice Queen: Her father tells Eiko, Chizuru, and Ika that ever since she started working with them, her sociability has been improved. She's still afraid of men though.
  • Dude Magnet: A lot of men love her.
  • The Faceless: Not exactly with her appearance (she's even actually quite the looker), but she's this personality-wise; as her father told Eiko, she cannot actively interact with people outside her masks.
  • Mad Scientist's Beautiful Daughter: Her dad is a bit of a Mad Scientist, but Ayumi herself is very cute and beautiful.
  • Meido: In Chapter 162 (Season 2, Episode 2.2 in the anime), she is this while working at the store and while wearing bladed brass knuckles! Needless to say, male customers are petrified at the unusual sight.
  • Not Good with People: At first, but she gets a lot better at interacting with people thanks to Ika (Granted, because she doesn't consider her human) and the others, especially Chizuru and Sanae.
  • The Quiet One: Doesn't talk to others without masks.
  • Shrinking Violet: Too afraid to talk to other people when she isn't wearing a mask. She's slowly but surely coming out of her shell thanks to Ika and the others.
  • Speaks Fluent Animal: Can understand animals like Alex, or at least claims she can. The others hope it's true.

    Mr. Tokita 

Mr. Tokita

Voiced by: Rikiya Koyama (Japanese), Tony Oliver (English, Media Blasters dub), Victor Lee (English, Animax dub)

Ayumi's father whose first name is unknown. He is the Southern Wind's owner. He is fond of making creepy kigurumi based on Ika.
  • Jerk with a Heart of Gold: He means well and he's generous, but he's one helluva grumpy old man.
  • Mad Scientist: His Ika kigurumi are both cute and creepy, but creepy most of the time. He even has built a toilet room out of them.
  • Nightmare Fuel Station Attendant
  • No Name Given: His first name is never revealed.
  • No Social Skills: His only method of communication is to bark out orders at people in an unpleasant manner.
  • Villain Team-Up: With Harris, Clark, and Martin. All of them are not really villainous; only to Ika (and even then, not all the time).
  • Why Did It Have to Be Snakes?: He's deathly afraid of dogs. When his daughter brought home an adorable stray puppy, he couldn't even stay in his own house until Eiko encouraged him to try and get over it.

    Harris, Clark and Martin 

Harris, Clark and Martin

Voiced by: Seiji Sasaki, Anri Katsu, and Tetsuo Goto (Japanese); "Phineas", Tony Oliver, and Jonathan Meza (English, Media Blasters dub)

A trio of American Mad Scientists and MIT graduates who, together with Cindy, investigate Ika.
  • Beware the Silly Ones: For as silly and bumbling as they are, they can be surprisingly competent when they put their minds to it.
  • Eagleland
  • Geek Physiques: Harris is a little skinny, Clark is very skinny, and Martin is fat.
    • When Ika is gone in episode 12.1, they become depressed — Harris and Clark gain a ton of weight, while Martin loses quite a bit.
  • Gratuitous English: Humorously, a few of their Gratuitous English lines go unaltered in the English dub. "You're a god, man! We are god men!"
  • Mad Scientist
  • Nightmare Fuel Station Attendant: Especially in chapter 113.
  • Reed Richards Is Useless: In their zeal to discover Ika's "alien" heritage, they conveniently overlook their other, far more important discoveries: a universal language translator and a cure for cancer. Being that we actually learn this from them, they appear to have some faint awareness of the fact that they're squandering their talents and discoveries
    • Probably they finance their wild-alien chase with the patent-money they get from these inventions?
  • Three Stooges Shout-Out: Their In-Series Nickname
  • Villain Team-Up: While they are not really villainous, the trio and Ayumi's father join forces in Season 2, Episode 11.2 to build a Mecha-Ika Musume. This Mecha-Ika has almost all of the original's powers as well as the ability to speak.

    Kiyomi Sakura 

Kiyomi Sakura

Voiced by: Kokoro Kikuchi (Japanese), Carrie Savage (English, Media Blasters dub), Jessica de Borja (English, Animax dub)

A middle-school student who Ika befriends after a prank gone wrong.
  • A-Cup Angst: She is so angsty about it that her original wish for Tanabata is to have a bigger bust. Kinda odd for a sweet girl such as herself.
  • The Chick: Chapter 387 shows she's the one who holds the Invasion Club together; without her, they descend into acrimony.
  • Meganekko: Wears glasses.
  • Nice Girl: She's an absolute sweetheart. Clearly seen in Chapter 185 of the manga, for example.

A policewoman who, despite what her job entails, is kinda incompetent.
  • Adorkable: She's clumsy and a bit incompetent, but bless her heart, she really tries.
  • Cute Clumsy Girl: So clumsy despite being a cop. She once tried to handcuff a purse-snatcher; she ended up cuffing his arm to her own.
  • Fair Cop: She's a really cute young woman alright. When she attempted to stand out less by changing from her police uniform into a bikini, it made her stand out even more.
  • Nice Girl: Clumsy and somewhat incompetent though she may be, she's really kind and eager to help and protect whoever she can.
  • No Sense of Direction: The focus of chapter 379 is her poor sense of direction, to her dismay. When she kept repeating a map's directions in her head to lead Ika where she needed to go, she was distracted by two kids reciting the Konami Code and ended up even more confused.
  • One of the Kids: Is not ashamed to join a water gun fight with Squid Girl and the other kids.
  • Police Are Useless: She was once held hostage when she accidentally cuffed herself detaining a criminal, and Squid Girl has saved her on more than one occasion.
  • Walking Swimsuit Scene: In one chapter, she changes from her police uniform into a bikini to stand out less. Unfortunately, that just makes her stand out even more.

    Ruka Shirosugi 

Ruka Shirosugi

A nurse working at the beach's first-aid station, and high school acquaintance of Keiko's. She's notable for being pretty scary when visited one too many times as a patient.
  • Dr. Jerk: There's a pattern to her: the first time you visit her as a patient, she's kind and reassuring. The second time, she gets mad and scary. The third time, you leave with more injuries than you came in with.
  • Former Teen Rebel: She was a notable deliquent in her high school days, but calmed down as she grew up. She notices the irony in her current job being the exact opposite of what she used to be. Though she does keep the scary attitude of a deliquent.
  • Irony: A Former Teen Rebel is now a nurse who tends to injured people. She lampshades the irony of the situation.
  • Jerk with a Heart of Gold: She's pretty scary, but she is a nurse who helps the beach stay safer, and is a good person deep down.
  • Terrible Artist: Her drawings come out as cutesy, Super-Deformed versions of whatever she was trying to draw. She's quite embarassed by it, and wants to improve.
