The Black Bulls get a sudden visit from Mereleona and she drags them to the strong magic region of the Yultim Volcano. There, the Crimson Lion Kings, as well as their captain, Fuegoleon, and his younger brother Leopold, were waiting for them. Asta and Noelle remember the hot springs they had visited on their previous trip there. Finding new resolve, Magna, Luck, Charmy, Gordon, and Nero all decide to train in the fiery underground cave of the volcano!
If you knew that thing was down here,
 you should've told us—
...كان عليك إخبارنا إن كنت تعلمين بوجود ذلك الشيء هنا
Warum haben Sie uns nicht gewarnt,
dass das Vieh hier ist.
-Podía habernos avisa…
-¡No sean consentidos!
-Podía habernos avisa…
-¡No seáis consentidos!
Vous auriez pu nous prévenir !
Poteva almeno avvisarci!
Se você sabia que tinha algo
aqui, você deveria ter nos dito...
Сказали бы сразу,
что тут монстр водится!
