Aiko is shown to be very kind towards her students, and was very well respected. But if someone wedges their way into her student's respect she becomes very jealous. Her envy the total opposite to that of her sister, who is terrified with Ika Musume.

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.

The sea in our world has been polluted. All sorts of trash were thrown into it, making it unpleasant deep down in the sea. One of the inhabitants of the sea, Ika Musume (Squid Girl) seeks to exact revenge on humanity for throwing trash into the sea. Clueless about the surface, she seeks to invade humanity alone, trying to rule over the world... only to find herself enslaved by one of the nearest beach-houses for breaking one side of the wall! <br><br>
