Bubble de House de Marumarumaru The Animation. About four months ago, Daisuke tried to move into a rental house for college students provided at a low price by a well-known bathroom manufacturer, on the condition of becoming a tester of their products. Daisuke thought he was doomed to fail because he wasn't selected in the initial selection, but suddenly he got the news that he was accepted! Excitedly, he moved there. However, once he settled in, Daisuke realized that the residents of this house, apart from me, were all girls! And they were his “Senpai” who attended the same university as him! Daisuke has seen them before, though they don't recognize him-which makes things even more awkward. It seems that there will be many heart-pounding moments in this rental house. A life together full of surprises in this “Bubble House” themed rental house begins!
