# List of Squid Girl episodes

Squid Girl, known in Japan as Shinryaku! Ika Musume (Invasion! Squid Girl), is an anime series produced by Diomedea based on the comedy manga series by Masahiro Anbe published in Weekly Shōnen Champion. The series tells of a Squid Girl who seeks to invade humanity as revenge for the pollution of the seas. However, due to accidentally breaking the wall of a beach house, she is forced to work as a waitress to pay off the damages.
The first season aired on TV Tokyo between October 4 and December 20, 2010, and was also released with English subtitles on Crunchyroll. The fifth and sixth DVD/Blu-ray volumes, released on April 20, 2011, and May 18, 2011, contain short "Mini-Ika Musume" episodes. A second anime season titled Shinryaku!? Ika Musume aired in Japan between September 26 and December 26, 2011. Three original video animation (OVA) episodes were released on August 8, 2012, June 7, 2013, and September 9, 2014, respectively. Crunchyroll began streaming the OVAs in February 2014.
Media Blasters licensed the anime in North America under the title Squid Girl. The first season was released on two DVD volumes on September 27 and December 6, 2011, respectively, followed by a Blu-ray Disc release on March 13, 2012. Media Blasters will also be releasing the second season. The first season was released on DVD in the United Kingdom by Manga Entertainment on August 13, 2012.
The first season uses two pieces of theme music: one opening theme and one ending theme. The opening theme is "Shinryaku no Susume" (侵略ノススメ☆, Let's Invade!) by Ultra-Prism with Hisako Kanemoto and the ending theme is "Metamerism" (メタメリズム, Metamerizumu) by Kanae Itō. For the second season, the opening theme is "High Powered" by Sphere, and the ending theme is "Learning About You" (君を知ること, Kimi o Shiru Koto) by Kanemoto. For the OVAs, the opening theme is "Let's Shinryaku Time!" (Let's☆侵略タイム!, Let's Shinryaku Taimu) by Ultra-Prism, the ending theme for the first two OVAs is "Puzzle" (パズル, Pazuru) by Itō, and the ending theme for the third OVA is "Miser's Dream" (マイザーズドリーム, Maizāzu Dorīmu) by Itō.
In Japanese, each episode's title is in the form of a negative question in order to end with nai ka and thus make a pun with the Japanese word for squid ika. The last two syllables (i, ka) are written with katakana instead of hiragana in order to emphasize the pun. Example: Shinryaku Shina-ika? (侵略しなイカ?)
