Since the trip to the great cathedral in Romalia has been cancelled, the students at Tristain Academy are heading to the beach for summer vacation; though when they arrive, both Saito and Guiche are disappointed at the girls' reserved swimming costumes. Luckily, help is at hand as Principal Ottoman just so happens to have located a large chest full of seductive swimwear in an aristocrat's manor and orders the young ladies to change into them! With the boys attempting to con the girls into wearing even skimpier bikinis and Louise hoping to secure a moonlit stroll on the beach with Saito, it's sure to be an eventful summer break for the Tristain students.
Like pervy and slightly pointless beach episodes of anime? Then look no further than both the ZnT Princess no Rondo Special and the Kamen no Maid Guy special. Both of these are "fun" episodes that take the chance to go above and beyond their normal ecchi content. If you enjoyed one, it may be worth checking out the other.
