The girls meet a new magical girl, Usagi!  But when the new girl turns out to be a monster, they'll have to become "a magical girl who's anxious to fight the enemy that's right in front of them, and a magical girl who's started to get worried about things at the worst possible time, and a perverted magical girl who's getting excited to realize that he's actually a boy!"  Can they break out of the spell and transform by giving a plausible explanation for what they'd do with 150 crabs?
If Usagi-chan has a Naria that 
means she's a magical girl, right?
إن كانت أوساغي-تشان تملك ناريا
 إذاً هي فتاة ساحرة أيضاً، صحيح؟
Wenn Usagi-chan ein Naria hat,
ist sie auch ein Magical Girl, richtig?
Si Usagi a un Naria, 
ça fait bien d’elle une magical girl ?
Se Usagi-chan ha un Naria
significa che è una guerriera magica, no?
Já que a Usagi tem Naria, ela 
também é uma garota mágica?
