The Seven Transformations of my Bathtub Circumstances (オレん家のフロ事情☆七変化 Orenchi no Furo Jijō: Maki-hen) is the eleventh episode of the anime series.
Tatsumi gets a raise from his boss and tells Wakasa that he can request something he likes, even if it's a little extravagant. Wakasa decides to try a milk bath, and his friends all appear with various potables they would like to bathe in: Mikuni with coffee, tea, and Aquari; Maki with orange juice; and Takasu with wine, beer, and sake. Tatsumi (who himself is underage) protests the last for fear of underage viewers getting ideas, but is beaten down by the others, who are all adults. During the sake bath Tatsumi becomes unable to handle the alcohol fumes and passes out, and Wakasa and company air out the room and change out the bath water for him. During the credits, being packed into the bath with so many sea creatures gives Tatsumi the idea to make seafood hotpot for dinner.
