The war is over, and it's time for a vacation! Yuuto and the gang travel to a vacation spot, where all the girls fight over who gets the right to wash Yuuto.
I'll let you serve me for 
the rest of the trip.
Ihr dürft mir für den Rest
des Ausflugs dienen.
Lascerò che mi serviate per il resto del viaggio.
Eu deixarei vocês me servirem
pelo resto da viagem.
Тогда можете услуживать 
мне до конца поездки.
