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?!
But I got you both caught 
up in my misfortune.
لكنّني أقحمتكما في تعاستي
Ich habe euch in mein Unglück gestürzt …
los involucré en esto
por culpa de mi mala suerte…
os involucré en esto
por culpa de mi mala suerte…
Sauf que je vous ai condamnés
avec ma malchance.
Ma entrambi siete finiti coinvolti
nella mia sfortuna.
Mas eu envolvi vocês
dois em meu infortúnio.
А в итоге из-за меня 
вас настигла неудача.
