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...
There's no telling how it will end 
if we fight fair and square.
من المستحيل معرفة النّتيجة 
.إن تقاتلنا بعدل وإنصاف
Niemand kann sagen, wie es ausgehen wird,
wenn wir offen und ehrlich gegeneinander antreten!
Descubriremos qué sucede
en un combate justo.
Descubriremos qué sucede
en un combate justo.
Nous verrons bien
qui de nous deux l’emportera !
È impossibile prevedere come andrà a finire 
se ci scontriamo lealmente.
Não dá pra saber o resultado se lutarmos
de forma limpa e justa!
Никто не знает, чем окончится наш бой на равных!
