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 royal lady from the Golden Dawn
 who arranged all of this...
السيدة الملكية من الفجر 
...الذهبي التي رتّبت لكلّ هذا
puis la princesse de l’Aube d’or,
qui a joué les médiatrices,
Poi la signorina nobile dell'Alba Dorata 
che ha organizzato tutto...
a dama da realeza do Alvorecer
Dourado que arrumou a viagem...
