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...
I need to infuse the Demon-Dweller 
Sword with my anti-magic!
!عليّ أن أشبع سيف الشيطان المستوطن بإلغاء السحر خاصتي
de la même façon que j’avais emprunté
son pouvoir à Noelle !
devo infondere nella Spada Alberga-Demoni 
la mia anti-magia!
Eu preciso infundir a Espada Habitante
do Demônio com minha antimagia!
надо вложить антимагию…
в своего Одержимого!
