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. (Source: Anime News Network)

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? (Source: Media Blasters)
OVA episode bundled with fifth volume of manga.
Based on Barasui's manga series, Ichigo Mashimaro follows the life of Nobue Itou, her younger sister Chika, and her friends. The basic premise of the show can be summed up in "cute girls do cute things in cute ways", be it trying to quit smoking, going outside to play, celebrating a holiday, or doing school work. This OVA picks up where the series left off, continuing the adventures of your everyday life, only cuter. (Source: AniDB)
