Sentai Filmworks announced on Tuesday that it has licensed the Squid Girl anime for streaming, television broadcast, and digital streaming. The license includes both the first and second series, as well as the OVA episodes.

Media Blaster previously released the first series on DVD and Blu-ray Disc with Japanese and English audio tracks. The series was streaming on Hulu, but expired earlier this year along with a number of other Media Blasters titles. Media Blasters had announced plans to release the second series in 2012.

Both seasons of the anime adapt Masahiro Anbe's comedy manga about a squid girl who vows to invade the beaches of mankind since humans have polluted the seas. However, her invasion is less than successful, and she ends up on dry land. The series ran from 2007 to 2016 in Akita Shoten's Weekly Shōnen Champion .

The media-distribution website Crunchyroll streamed both seasons of the series in several countries outside of Japan as they aired.
