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…
You're thinking something 
naughty again, aren't you?
Du hast gerade sicher wieder
schmutzige Gedanken.
Volviste a imaginar algo indecente.
Te has vuelto a imaginar algo indecente.
T’as encore
l’imagination débordante…
Rieccoti a elucubrare roba zozza
in quella testolina...
Você está pensando em coisas 
pervertidas de novo, não está?
