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?!
It all happened because you 
were possessed by an elf!
!كلّ هذا حدث لأنّ إلفًا كان يستحوذ عليك
Das war doch alles der Elf,
der deinen Körper übernommen hatte.
On verra que c’est pas toi,
mais l’elfe qui te possédait…
È successo tutto perché eri posseduto da un elfo!
Isso tudo aconteceu porque
você foi possuído por um elfo!
Это всё эльф,
что сидел в твоём теле!
