Kazuki's parents are on their way to visit and the girls overhear.  Kuriko finds out that they like to eat eel.  She heads off to find the best cooks for eel in order to impress Kazuki's parents.  Yuuna goes to get eel also but she has a horrible aversion to anything slimy and cannot make herself fix the dish.  Rin, who is now starting to like Kazuki because of his help with the bento, is practicing her formal manners so as to impress Kazuki's parents as well.  Of course, all comes to naught when Kazuki's parents call up and cancel.
