The girls take a vacation at Inaho's villa, only to be attacked by a monster maid!   The monster puts them in a delicate situation, where one girls comes to their villa only to find a squatter living there already, and then somebody else comes to do an open house.  An epic villa-pun battle breaks out to determine who will win the villa.  Can they transform while sharing their bitter summer memories and defeat this villa villain?
That was the most fun thing that 
happened to me this summer.
كان ذلك أكثر شيءٍ مسلٍّ حدث لي هذا الصيف
Das ist das Lustigste,
was mir diesen Sommer passiert ist.
Fue el recuerdo más gracioso
de todo el verano.

C’est mon souvenir
le plus drôle de cet été.
Questa è la cosa più divertente
che mi è successa quest'estate-ja.
Foi a coisa mais divertida
