...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.
Carla-chan played the necromancer 
possessed by the evil spirit.
.كارلا-تشان لعبت دور مستحضرة الأرواح التي تملكتها الروح الشريرة
und Carla die von einem bösen Geist
besessene Totenbeschwörerin.
Carla era la nigromante poseída
por el espíritu maligno.
Carla era la nigromante poseída
por el espíritu maligno.
tandis que Carla était
la nécromancienne possédée,
Carla era la necromante
posseduta dallo spirito malvagio.
A Carla-chan fez o papel de necromante
possuída por um espírito maligno.
а Карла была некромантом,
в которого вселился дух.
