Seiichi and Saria train under Artoria to become adventurers. During their training the three of them are teleported into a dungeon by a demon’s trap.

The dungeon they find themselves in the stronghold of the Black Dragon God, the strongest member of the Demon Lord’s Army. Artoria gets separated from Seiichi and Saria in the dungeon and the giant Black Dragon God appears before her. Then that overwhelming threat attacks! Can Seiichi and Saria save her in time?!
Try not to get separated 
in the first place, though.
حاولا ألّا تنفصلا في المقام الأوّل
Aber schaut, dass ihr euch
nicht von mir trennt.
Pero no se vayan a separar, ¿eh?
Pero no os separéis, ¿eh?
Mais bon, ne vous éloignez pas.
Però pensiamo prima di tutto 
a non separarci, ok?
Alias, o melhor é não se perderem de mim.
Только не вздумайте разделяться!
