Falfa woke up in the form of a slime! Of course, that's not too shocking since she's a slime spirit, but her sister Shalsha laments that this has never happened before and she doesn't know how to change her back.So Azusa sets off with Shalsha and Beelzebub in search of an "unusual slime" who might know a way to change Falfa back...
So this slime can't be 
anyone but my sister.
لذلك لا يمكن أن يكون هذا السلايم
.أيّ أحد آخر سوى أختي
Bei diesem Schleim kann es sich daher
nur um meine große Schwester handeln.
Quindi questo slime dev'essere per forza mia sorella.
Ou seja, esse slime só pode
ser a minha irmã.
Так что вывод один: эта слизь
 и есть моя сестра.
