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?!
I want humans to interact with me again!
!أريد أن يتفاعل البشر معي مجدّداً
Ich will, dass sich noch einmal
ein Mensch nach mir umschaut!
Quiero que los humanos
vuelvan a tomarme en cuenta.
Quiero que los humanos
vuelvan a tenerme en cuenta.
Si seulement
un humain pouvait m’ouvrir !
Voglio che gli umani 
interagiscano ancora con me!
Eu quero que os humanos
interajam comigo mais uma vez!
Хочу, чтобы люди снова меня открывали!
