يذهب يامي وأستا إلى قائدة فرسان الوردة الزرقاء للسؤال عن لعنتها من أجل بعض الدلائل عن الشياطين

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?!

The War against the Spade Kingdom begins in earnest as the Heart Kingdom and Black Bulls come under attack by Dante and Vanica of the Dark Triad.

As the battles in the Heart Kingdom begin to come to an end, Asta and Yami decide to work together as they continue in their fight against Dante Zogratis of the Dark Triad.
