A girl who works at the Lemon Beach House alongside her older sister.

After [Ika](https://anilist.co/character/20512/Ika-Musume) fails to invade the surface, she forces them to work for her to pay off a part of the wall she destroyed. She is the younger sister to [Chizuru Aizawa](https://anilist.co/character/34654/Chizuru-Aizawa) and older sister to [Takeru Aizawa](https://anilist.co/character/37242/Takeru-Aizawa). She is typically the one who is the most annoyed by Squid Girl's antics, getting easily frustrated with them and not showing much concern for her well-being or safety.

Foolish land-born air breathers! Behold the terror from the depths, the tentacled conqueror of humanity: Squid Girl! With your pollution and stuff you really deserve it, so prepare for menacing, inky doom! 
Squid Girl has come from the depths of the sea to conquer humanity for its pollution of the ocean. Within moments of arriving on the surface world, our easily distracted, little invertebrate is promptly bullied into working for the Aizawa sisters as a waitress, supplying their restaurant with squid ink. If poor Squid Girl can't handle two pushy Japanese girls, how will she ever subjugate the human race?

The nefarious Squid Girl is back to continue her self-appointed mission to invade the surface world. Or that's what she would do, if she could just stop getting distracted by squidding movies, reading squidly manga, and making friends as only a squid could make them. Squid Girl must overcome not only danger found at every turn, but her own squidly good nature as well.

The sea in our world has been polluted. All sorts of trash were thrown into it, making it unpleasant deep down in the sea. One of the inhabitants of the sea, Ika Musume (Squid Girl) seeks to exact revenge on humanity for throwing trash into the sea. Clueless about the surface, she seeks to invade humanity alone, trying to rule over the world... only to find herself enslaved by one of the nearest beach-houses for breaking one side of the wall!
