Squid Girl, known in Japan as Shinryaku! Ika Musume (侵略!イカ娘, lit. Invasion! Squid Girl) with the subtitle The invader comes from the bottom of the sea!, is a Japanese manga series by Masahiro Anbe, which was serialized in Akita Shoten's Weekly Shōnen Champion between July 2007 and February 2016. An anime television series adaptation produced by Diomedéa aired on TV Tokyo between October and December 2010, with a second season airing between September and December 2011. Three original video animation (OVA) episodes were released between 2012 and 2014.


Vowing to take over the world as revenge for polluting the ocean, Squid Girl attempts to make her base of operations the Lemon Beach House (alt. Lemon Beach Shack), a small beachside restaurant run by the Aizawa siblings. However, when she accidentally breaks a hole in their wall trying to demonstrate her power by trying to swat a mosquito, she is forced to work as a waitress to pay off the damages. Thus, Squid Girl begins her life on the surface, learning new things and encountering many curious visitors.


Main characters[edit]

Squid Girl (イカ娘, Ika Musume)
Voiced by: Hisako Kanemoto (Japanese); Christine Marie Cabanos (English)[1][2][3]
Squid Girl appears as a young humanoid girl with blue cephalopod tentacles for hair. Her goal is to take over humanity as punishment for the pollution done to the sea. However, after causing damage to Lemon (which she planned to use as a base), she was forced to work as a waitress to pay for the damages. She possesses numerous squid abilities including extending her tentacles, regenerating severed ones, spewing squid ink from her mouth, glowing in the dark like the firefly squid, swimming and breathing underwater. She also has bracelets that enable her to have weight-shifting abilities.S2 Ep. 2c It is later revealed that what appears as her white squid-shaped skullcap is actually part of her head, so fatal consequences might occur if someone was to attempt removing her "cap". The two fins on her "cap" can move like actual squid fins, although she was initially ignorant of the fact. Her favorite food is shrimp, and she greatly fears natural predators of squids like sharks and killer whales to the point that even swimming floats of such creatures terrify her. Although generally immature at first and often getting herself into mischief from the start, she is a fast learner, able to master complex things such as math and other languages in a short period of time.

Despite her frequent irritation towards Squid Girl, Eiko does seem to care for her more than she is willing to admit and the two eventually become good friends.
