Squid Girl

Ika gets a fever, which she believes to be a special Squidgirl disease revolving around a craving for shrimp, so Eiko tries to help her stay off shrimp until she gets better. Later, Ika learns about the fins on her hat and everyone tries to figure out what they are used for. She also gets into a debate with one of Takeru’s friends over sandcastles. Later, Ika becomes fascinated by umbrellas believing them to be ideal weapons.

Concerned about any evil plans Ika may have, Nagisa decides to sleep over at the Aizawas to keep watch on her. Nagisa pretends to not be scared of Ika, which upsets her. Eiko tries to convince Ika to just be friends with Nagisa, but Nagisa’s fear rises up again. As Ika decides to play as being Queen, Cindy manages to trick her into agreeing to come to her secret laboratory, where she meets some her strange co-workers; Harris, Clark and Martin. Later, the girls run into the Southern Winds owner’s daughter, and offer her a trial run working at the Lemon. As she attracts more sales, Eiko lets the owner have Ika for the Southern Winds, where she proves to be a worthwhile entertainer.

A hero show is performed on the beach for the kids, though the performers run into a bit of trouble when Ika somehow manages to get everyone to cheer for the villain. When Ika then takes the costume for herself, Chizuru acts as a guest character to set her straight. Later, Eiko is shocked to find Ika is able to solve complex math problems. She reluctantly asks her to teach her how to study, only to find the technique is illegible to humans. After Gorō rescues her from drowning, Nagisa becomes concerned that he may have been brainwashed into thinking Ika isn’t a threat, leading to some strange misunderstandings.

A woman named Cindy Campbell who comes from a US extraterrestrial research laboratory believes Ika to be an alien and wants to take her back to her lab. Cindy attempts to brainwash Ika into thinking she’s an alien, but her appetite snaps her out of it. Later, Ika has a look around Eiko’s school, believing it to be a military base. She decides to hold the principal captive and take over the school before Eiko stops her. Later, Sanae has a dream in which Eiko finds a miniaturized Ika and keeps it as a pet.

When Ika finds a lost wallet, the owner rewards her with 10,000 yen, which she spends on frozen shrimp. When the TV in the beach house breaks down, Ika is invited to sleep over at the Aizawa household. While exploring the beach, Ika and Eiko find an imitation Squid Girl built by the owner of a rival beach house, Southern Winds, to attract customers. The owner challenges Eiko to various matches for possession of the original, though the imitation’s efforts prove scary.

The gang take Ika, who had never heard of ghosts before, on a test of courage at the local cemetery, but she just ends up scaring everyone with her ability to emit light. Later, Ika becomes frightened when inflatable killer whales start showing up around the place (believing they are real), since killer whales are her natural predator. When Takeru asks Gorō to teach him how to swim, Ika tries to teach him to avoid the whales. Later, a new girl, Nagisa Saitō, joins the stand, though is a bit nervous around Ika, who becomes pleased that someone actually fears her.

Ika meets lifesaver, Gorō Arashiyama, though gets annoyed when he doesn’t live up to her definition of "protector of the sea." Ika tries to drown him to show him up, but this in turn prevents him from reaching a kid trapped in a current, so Ika must save her herself. After witnessing a birthday party, Ika decides she wants one as well, so the Aizawa sisters hold a party for her before playing with some fireworks. Ika later meets Aiko’s friend Sanae Nagatsuki, who takes a creepy liking towards her and forces her to cosplay for her personal photo collection.

Angered by the pollution in the seas, a squid girl named Ika Musume comes from the sea and declares the invasion of Earth at a nearby yakisoba stand, but isn’t taken seriously due to her small stature. When she goes to plead her case, she is mistaken for a waitress, which puts the responsibility of invading the world into perspective. When she breaks a hole in the store with her tentacles trying to hit a mosquito, the store manager, Eiko Aizawa, puts her to work in order to pay for the damages. Later, Ika meets Eiko’s little brother, Takeru, who goes to great lengths to pretend to be a squid-person so he can be Ika’s comrade. During a rainy day where there are few customers, Ika takes the opportunity to try and take over the stand, but is overpowered by the eldest sister, Chizuru. As punishment, Ika is forced to use her own ink to make Squid Ink Spaghetti, which becomes popular.
