* GamerChick: Keeps a UsefulNotes/{{Famicom}} lookalike inside her room (in the anime it's a UsefulNotes/MegaDrive lookalike). Oftentimes Ika is her playmate. She even says that gaming is her life!

** On the other hand, in the Brazilian Portuguese dub, she is named just as "Ika", her original Japanese name, since the word for squid in Portuguese, "lula", is also a proper name there, as well as being the surname of the current president of Brazil, Luiz Inácio ''Lula'' da Silva.

->Voiced by: Creator/AyakoKawasumi (Japanese), Creator/SarahWilliams (season 1), Creator/AllisonSumrall (season 2) (English)

** The accent is gone as of Season 2's 4.1, where she spends the whole segment speaking SurprisinglyGoodEnglish.

* NotGoodWithPeople: 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.

* TheChick: Chapter 387 shows she's the one who holds the Invasion Club together; without her, they descend into acrimony.

* AntennaHair

* {{Bishonen}}

* MrFanservice: AND HOW!

A lifeguard and Eiko's childhood friend, who has feelings for Chizuru.

* AmbiguouslyBrown: His tan is justifiable with his career.
* {{Bishonen}}
* ChildhoodFriends: With Eiko. It is also through this friendship that he met and fell in love with Chizuru.
* DoggedNiceGuy: That includes getting his butt kicked by Chizuru.
* MrFanservice: AND HOW!
* SitcomArchnemesis: Is sometimes seen as this by Ika.
* StalkerWithACrush: Not exactly a stalker, but he keeps lots of pictures of Chizuru.
* WalkingShirtlessScene: Given his job, this is to be expected.
* WhyDidItHaveToBeSnakes: Fears ghosts.

->'''Voiced by:''' Creator/HitomiNabatame (Japanese), Creator/LauraPost (season 1), Creator/ShelleyCaleneBlack (English), Alicia Barragan (Latin American Spanish)

An American alien researcher who comes to Japan to investigate Ika.

* AlliterativeName: '''C'''indy '''C'''ampbell.
* AnimeAccentAbsence: 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 SurprisinglyGoodEnglish.
* CelebrityResemblance: In chapter 245, she's mistaken for the world-famous charismatic singer Jennifer, much to her chagrin.
* {{Eagleland}}
* EveryoneHasStandards: When invited to the Aizawa residence to teach Takeru English, not only did she wear regular clothes compared to her [[MsFanservice usual bikini]], but she did not have obsession with Ika Musume as an alien.
* GorgeousGaijin: A sexy blonde American woman with a pony-tail, wearing a parka over a two-piece bikini or a tube-top and short shorts? Yes, please.
* MadScientist: Less so than the Three Stooges, but still.
* PhenotypeStereotype: Blond and well-endowed.
* SingleTargetSexuality: Her obsession with Ika sometimes goes beyond finding her "alien heritage" and she's heading right in Sanae's direction.
* TooKinkyToTorture: Much like Sanae, she doesn't mind being on the blunt end of Ika's tentacles.
* WalkingSwimsuitScene: Is almost always seen in her swimsuit.

->'''Voiced by:''' Azusa Enoki (Japanese), Creator/CristinaValenzuela (season 1), Creator/StephanieWittels (season 2) Jessica de Borja (Animax) (English)

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

[[folder:Aiko Saito]]
!! Aiko Saito
[[quoteright:170:https://static.tvtropes.org/pmwiki/pub/images/screenshot_2018_02_24_162839.png]]

->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.
----
* CantHoldHerLiquor: 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.
* FriendToAllChildren: Parodied. She loves teaching children, and the children love her back, but they tend to like Ika more, which causes Aiko no shortage of jealousy and dismay.
* TheRival: Sees Ika as this, for having "stolen" her popularity with the kids.
* SenseiChan: Young, beautiful, and at times surprisingly immature for a teacher. In chapter 374, Nagisa tells her the reason she's not popular with her students is because she looks down on childish pastimes. Her solution is to put on a sundress and a big hair bow, find the neighborhood children, and ask them to call her Aiko-chan while she plays with them.
* WhyDidItHaveToBeSnakes: Being a teacher, she's knowledgeable about bugs, but she's still terrified of them.

[[folder:Mr. Tokita]]
!!Mr. Tokita
[[quoteright:195:https://static.tvtropes.org/pmwiki/pub/images/shinryaku__mr_tokita_1132.jpg]]

->'''Voiced by:''' Creator/RikiyaKoyama (Japanese), Creator/TonyOliver (season 1), Victor Lee (Animax) (English)

Ayumi's father, first name unknown. He owns the Southern Wind beach house and is fond of making creepy kigurumi based on Ika.

* JerkWithAHeartOfGold: He's one helluva grumpy old man, but he means well and he's generous. For one example, when his daughter brought home a stray puppy, he didn't think for a second about kicking it out despite his fear; he instead allowed her to keep it and kicked ''himself'' out. Eiko and Ika lampshade how he's a surprisingly nice guy.
* MadScientist: His Ika kigurumi are both cute and creepy, but creepy most of the time. He even has built a ''toilet room'' out of them.
* NightmareFuelStationAttendant
* NoNameGiven: His first name is never revealed.
* NoSocialSkills: His only method of communication is to bark out orders at people in an unpleasant manner.
* VillainTeamUp: With Harris, Clark, and Martin. All of them are not really villainous; ''only to Ika'' (and even then, not all the time).
* WhyDidItHaveToBeSnakes: 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.

[[folder:Harris, Clark and Martin]]
!!Harris, Clark and Martin
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/shinryaku__harris_clark_martin_9079.jpg]]

->'''Voiced by:''' Seiji Sasaki, Creator/AnriKatsu, and Tetsuo Goto (Japanese); "Phineas", Creator/TonyOliver, and Jonathan Meza (season 1), Creator/AndrewLove, Creator/JayHickman, and Mark X. Laskowski (season 2) (English)

A trio of American {{Mad Scientist}}s and MIT graduates who, together with Cindy, investigate Ika.

* BewareTheSillyOnes: For as silly and bumbling as they are, they can be surprisingly competent when they put their minds to it.
* {{Eagleland}}
* GeekPhysiques: 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.
* GratuitousEnglish: Humorously, a few of their Gratuitous English lines go unaltered in the English dub. "You're a god, man! We are god men!"
* MadScientist: A trio of 'em. Their inventions are usually annoying at best, creepy at worst, but rarely helpful.
* NightmareFuelStationAttendant: Especially in chapter 113.
* ReedRichardsIsUseless: 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?
* ThreeStoogesShoutOut: Their InSeriesNickname
* VillainTeamUp: While they are not really villainous, the trio and Ayumi's father join forces in Season 2, Episode 11.2 to build a [[RobotMe Mecha-Ika Musume]]. This Mecha-Ika has almost all of the original's powers as well as the ability to speak.

[[folder:Kiyomi Sakura]]
!!Kiyomi Sakura
[[quoteright:200:https://static.tvtropes.org/pmwiki/pub/images/shinryaku__kiyomi_sakura_5680.jpg]]

->'''Voiced by:''' Creator/KokoroKikuchi (Japanese), Creator/CarrieSavage (season 1), Creator/BrittneyKarbowski (season 2), Jessica de Borja (Animax) (English)

A middle-school student who Ika befriends after a prank gone wrong.

* ACupAngst: Kinda odd for a sweet girl such as herself, but she's not very happy about her lack of a chest for now; though she does acknowledge that she's just starting to grow up. She is so angsty about it that [[spoiler:her original wish for UsefulNotes/{{Tanabata}} is to ''have a bigger bust.'']]
* BespectacledCutie: Kiyomi Sakura, who also fits the trope's other traits, in that she's very kind, cute and sweet. According to one of the author notes, this was enforced as the author realized there were no glasses-wearing characters before her.
* TheChick: Chapter 387 shows she's the one who holds the Invasion Club together; without her, they descend into acrimony.
* TheCutie: ''So much''; she's very cute, kind and sweet, and the rest of the cast likes her a lot for it.
* NiceGirl: She's an absolute sweetheart. Clearly seen in Chapter 185 of the manga, for example.
* TheRival: Sanae sees her as this. Of course, this has something to do with [[LoveTriangle Ika.]] Although Sanae does want to become friends with her anyway, even if only as a means to get closer to Ika. [[spoiler:Then genuinely when Kiyomi accidentally finds out about Sanae's secret.]]
* SailorFuku: Only when at school, of course. She tends to wear a simpler dress and sandals when going casual.
* SeriousBusiness: Downplayed, as she remains sweet and kind about it, but she is very passionate about badminton.
* SickEpisode: At the end of Season 2 episode 7.3.
* TakingTheBullet: In chapter 285, she eats the entire bag of Sanae's awful-tasting cookies, to prevent Ika from stating the truth and hurting Sanae's feelings. The poor girl ends up fainting for her trouble.
* YouAreBetterThanYouThinkYouAre: With her being the "you" in question: she has nothing but praise for other people, but her own confidence is low, so Ika and most of the gang decide to improve it by cheering her on. Although it didn't work; while she's great at giving compliments, she's bad at ''taking'' them and ended up feeling embarassed.

[[folder:Tatsuo Isozaki]]
!!Tatsuo Isozaki
[[quoteright:180:https://static.tvtropes.org/pmwiki/pub/images/shinryaku__tatsuo_isozaki_9704.jpg]]

->'''Voiced by:''' Shinzou Miyasaka (Japanese), Philip Hays (English)

Goro's friend and fellow lifeguard who tries to flirt with Ayumi.

* AmbiguouslyBrown: Like Goro, his tan is justifiable with his career.
* CasanovaWannabe: Tries to flirt with Ayumi, much to the annoyance of Eiko.
* DidntThinkThisThrough: He's spent so much time getting shot down that when Cindy actually agrees to go out with him, he stammers uselessly until he bails.
* MrFanservice: For the same reason as Goro.
* OOCIsSeriousBusiness: He once remade himself as a "herbivore man" who renounces chasing after women. Eiko and Ika are immediately suspicous and start tailing him. Sure enough, they discover it's a ploy to make himself more attractive to women.
* PerverseSexualLust: He's absolutely obsessed with Misaki-chan, a female fighting game character. He uses her victory pose to soothe his "broken soul" after striking out with real girls. Although he refuses to buy otaku merch so he can try and keep his dignity, through a convoluted series of events he ends up with multiple Misaki figures, including a life-sized one.
* WalkingShirtlessScene: Almost always seen without a shirt.

-->'''Voiced by:''' Misato Fukuen (Japanese)

A policewoman who, despite what her job entails, is kinda incompetent.
----
* CuteClumsyGirl: So clumsy despite being a cop. She once tried to handcuff a purse-snatcher; she ended up cuffing his arm to her own.
* FairCop: 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.
* NiceGirl: Clumsy and somewhat incompetent though she may be, she's really kind and eager to help and protect whoever she can.
* NoSenseOfDirection: 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.
* OneOfTheKids: Is not ashamed to join a water gun fight with Squid Girl and the other kids.
* PoliceAreUseless: She was once held hostage when she accidentally cuffed herself detaining a criminal, and Squid Girl has saved her on more than one occasion.
* WalkingSwimsuitScene: 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.

[[folder:Kozue Tanabe]]
!!Kozue Tanabe
[[quoteright:200:https://static.tvtropes.org/pmwiki/pub/images/shinryaku__kozue_tanabe_1822.jpg]]

->'''Voiced by:''' Creator/AkemiKanda (Japanese), Creator/ErikaHarlacher (season 1) (English)

A gentle girl that Squid Girl meets one day on the beach. [[spoiler:Implied to be an anthropomorphic "tako musume" (octopus girl)]].
-----
* AmbiguouslyHuman: Her hat is commented to be as odd looking as whatever Ika has on her head...
* HumansAreFlawed: Her basic philosophy, which she sometimes shares with Ika.
* LastEpisodeNewCharacter: More like the Last Episode [[spoiler:Octo-]]Girl of the show. She has only appeared in the last episodes of Season 1 and 2.
* MeaningfulName: [[spoiler:'''Ta'''nabe '''Ko'''zue. "Tako" is Japanese for octopus.]]
* MysteriousStranger
* NiceGirl: Usually nice and sweet to others.
* TheBusCameBack: After being absent for hundreds of chapters, she reappears in the last volume's omake for a quick gag about octopus cannibalism.
* ThereIsAnother: [[spoiler: Is hinted to be an octopus girl.]]

* HotScientist: A scientist, and very pretty.

* ShesGotLegs: Which is rather apparent when she's donning her bathing suit, but it gets more emphasis in episode 3.

* ShesGotLegs: In episode 11 Sanae's slender legs get quite a bit of emphasis, for some reason.

* DubNameChange: Played straight on English (Squid Girl), but oddly ''inverted'' in the Latin American Spanish, when her Japanese name "Ika Musume" is kept, very likely for avoiding LipLock, as any of her possible translations to Spanish of her name ("Niña Calamar" or "Calamarcilla") doesn't fit in the translation.

* CryCute: 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).

* NiceHat: It's more than just a NiceHat, she needs it to live.

* LoveMakesYouCrazy: Turned UpToEleven 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.

* {{Meganekko}}: When she went to teach Eiko, Takeru and Ika English, she wore glasses. They're not PurelyAestheticGlasses either, she does need them; she simply usually wears contacts on other occasions.

* {{Meganekko}}: Wears glasses; enforced by the author, who designed her after he realized there were no major recurring characters with glasses before her.

* {{Meganekko}}: Briefly went under the impression that SmartPeopleWearGlasses, so she wore a pair of PurelyAestheticGlasses to become smarter. It doesn't work that way, but it did make her even cuter than usual. And naturally, when she tried Kiyomi's real glasses for a moment, it made her dizzy.

* YouGottaHaveBlueHair: Has blue hair-like tentacles.

* YouGottaHaveBlueHair

* PungeonMaster: In the dub, where she [[IncrediblyLamePun gets kraken]] with a bunch of fish puns instead of her verbal tic.

A lifeguard and Eiko's childhood friend, who has his sights for Chizuru.

* MetaGirl: Quite possibly, being the only character of the series to acknowledge [[spoiler:the [[MilestoneCelebration three-hundredth chapter]] of the manga]]]
