While Asta and the others were training in the Heart Kingdom, back in the Clover Kingdom, Yami asked Mereoleona to help him train. They start their training immediately and Yami is no match against Mereoleona who is a master at using Mana Zone. Meanwhile, the Spade Kingdom's forces continues to draw nearer as it continues its invasion...
They're fighting like, "kaboom," 
and getting better like, "fabam"!
!إنّهما يقاتلان هكذا، ويتحسنان هكذا
Sie machen Krach und Bumm im Kampf
und werden ratzfatz stärker.
Elles se battent
et progressent à vue d’œil.
Combattono tipo bam e sbang,
e migliorano a vista d'occhio tipo wooooh.
Elas tão melhorando,
bem cabum, ficando bem voosh.
«Ды-дыщ» как сражаются!
«Бу-бух» всё получается!
