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'd say Noelle and Nero have grown the most.
.فأكثر من تطور هما نويل ونيرو
Noelle et Nero sont en tête, non ?
direi che Noelle e Nero

eu diria que a Noelle e a Nero
foram as que mais progrediram.
