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...
If I enter it and prove that I'm 
stronger than Fighter Slime,
،إن شاركت وأثبتّ أنّني أقوى من المقاتلة السلايم
Wenn ich auch daran teilnehme
Si participo
y le demuestro que soy fuerte,
Si participo
y le demuestro que soy fuerte,
Si je peux prouver à cette slime

Se mi iscrivo e dimostro che 
sono più forte dello Slime Lottatore,
Se eu entrar e provar que sou mais
forte que a Slime Lutadora,
Если буду драться и докажу, что
 я сильнее Бойцовской слизи,
