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?!
But do you really think you'll 
get away with harming a friend
لكن هل تظنون أنّكم ستفلتون بأذية أحد
aber du glaubst doch nicht,
dass du ungeschoren davonkommst,
¿pero creen
que podrán lastimar sin más
pero ¿creéis que podréis hacer daño
mais crois pas t’en tirer indemne
après t’en être pris
Ma credi davvero di poter ferire l'amico 
di un membro della famiglia reale di Clover
Mas acha mesmo que
vai se safar após mexer
но подняв руку на друзей
наследницы престола Клевера…
