Thanks to Gordon’s father, Asta and the others were able to find out that there might be clues surrounding the devils in the Heart Kingdom and manage to get permission to enter the kingdom due to the fact that Mimosa had gone there previously to study overbroad. Asta, Noelle, Finral, Mimosa and Nero head to the Heart Kingdom. Asta and the others initially enjoy their trip there, but something that Langris told Finral had been bugging Finral. Suddenly, Asta and the others are faced with a rather unexpected trial. Will Asta and the other Black Bulls be able to obtain information on the devils?!
In every generation, 
the queen has made a pact
وفي كلّ جيل، تعقد الملكة اتفاقًا
In jeder Generation hat die Königin
einen Bund mit dem Wassergeist geschlossen
La reina de cada generación es
la sacerdotisa del espíritu del agua
La reina de cada generación es
la sacerdotisa del espíritu del agua
Prêtresses qu’elles sont,
nos souveraines s’unissent depuis
La regina di ciascuna generazione 
stipula un patto con lo Spirito dell'Acqua,
A cada geração, a rainha faz um pacto
Из поколения в поколение наши королевы
заключают пакт с духами воды.
