...Alvin gets out of the cell safe and sound but now that Carla and Maria are unexpectedly getting along they continue leading him around by the nose and it happens that Maria has a sweet little sister named Ellie and while avoiding spoilers regarding what trouble Ellie's gotten into it does concern Maria's status as a necromancer but I hope you won't get your hopes up for another cute female character to appear but in exchange Carla will attempt an unusual cosplay so that's the part you can look forward to and that's the deal with episode 8.
That's an insult to little 
sisters everywhere!
!هذه إساءة للأخوات الصغيرات في كل مكان
Das war ein Schlag ins Gesicht für alle
echten Schwestern da draußen!
¡Insultas a las hermanitas del mundo!
¡Insultas a las hermanitas del mundo!
Excuse-toi
auprès des petites sœurs !
Hai appena offeso tutte le sorelline del mondo!
Você precisa pedir desculpas
a todas as irmãs mais novas!
Это оскорбление для всех сестричек!
