Ren and the gang visit a hot-spring resort after being invited by Mana. 
Just when they all think they can relax, 
something causes the hot water in the springs to boil. 
And then, Lucifer and Raphael appear…
If we're not careful, our 
panties might show...
Ten cuidado o se te verán.
Ten cuidado, se te van a ver.
Faites attention,
ou on va tout voir !
Se non stiamo attente,
ci vedranno le mutandine...
Se não tomarmos cuidado, talvez
 dê pra ver nossa calcinha...
