Koma sees Oga and Baby Beel practicing Super Milk Time and starts to think that if Aoi eats his Manju, he and Aoi will also switch bodies. Koma tries many different techniques but is rejected Aoi every single time. A distressed Koma asks Baby Beel and Kota for help. Kota tell his a forbidden technique ( chopping the manju into fine pieces and mixing it into Aoi's food), although this almost works, Aoi notices a perverted reaction on Koma's face and beats him. Mean a while Hilda wins tickets to the hot spring and the whole Oga family goes on a vacation to the hot spring where they are greeted by an very odd looking lady (whom Oga mistakes for a demon). there Oga, Baby Beel and Hilda go for a hot bath where Hilda tells Oga about her family. Elsewhere Furuichi is enjoying skiing with some girls, Alaindelon interrupts and transports Furuichi where Oga and the other are. There Furuichi enters the mixed bath where Hilda is ( although he is unaware of this). Furuichi hears Hilda and Oga talking and realizes that Hilda is in the same bath and tries to approach but before he could do so Hilda exists the bath and Furuichi accidentally approaches the odd looking lady. Later Oga along with Hilda and Baby Beel are sleeping in their room and Furuichi and Alaindelon are cruled up into a blanket at the corner ( although Oga and the other are completely unaware of this)
