Squid Girl accompanies Takeru to the first day of school. As usual, the kids love her, which leads the kids' teacher to get quite irate. Then she leads Takeru's class on an invasion, but end up in a soccer match with another class. But she can't use her tentacles well and... Eiko and Chizuru notice that the house at the sea, Lemon, have very few female customers, so they ask Nagisa to dress like a guy. The plan works out and when Nagisa is in character, she is not even afraid of Squid Girl. While the sisters are plotting how to get even more female guests in, the proprietor of the South Wind appears. When Sanae appears on the verge of death in a diet suit in the heat of the summer, Squid Girl ask her what a diet is and the conversation shifts to body weight. When Squid Girl steps on the scale, it shows 100kg. Is this a new secret of her?
