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?!
Come to think of it, I think Mimosa mentioned 
going to the Heart Kingdom before.
بالمناسبة، أظنّ أنّ ميموزا 
.ذكرت الذهاب لمملكة هارت من قبل
Ich glaube mich erinnern zu können, dass Mimosa
mal sagte, dass sie in Heart gewesen wäre.
Ahora que lo pienso, Mimosa mencionó
haber estado en el Reino del Corazón.
Ahora que lo pienso, Mimosa mencionó
haber estado en el Reino del Corazón.
Au fait, Mimosa m’a raconté
qu’elle y était allée, autrefois.
Ora che ci penso, mi pare che Mimosa avesse detto 
di essere già stata nel Regno di Heart.
Se bem me lembro, eu acho que a Mimosa
já mencionou ter ido ao Reino Heart.
Кстати говоря, помнится…
Мимоза уже бывала в королевстве Черв!
