This year's 13th issue of Akita Shoten's Weekly Shonen Champion magazine is announcing on Thursday that production on a second season of the Squid Girl (Shinryaku! Ika Musume) television anime series has been green-lit. The premiere date has not yet been announced.

The anime adapts Masahiro Anbe's Shinryaku! Ika Musume (The Invader Came From the Bottom of the Sea!) 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 first season premiered in October, and the media-distribution website Crunchyroll streamed the anime outside Japan as it aired.
