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've now seen the powers of the Demon-Slayer
 Sword and the Demon-Destroyer Sword.
.رأيت الآن قوى سيف قاتل التنين وسيف مدمّر التنين
Du hast mir das Dämonenspalterschwert
und das Dämonenauslöscherschwert gezeigt.
Ya sé cómo funcionan las espadas
matademonios y erradicamagia.
Ya sé cómo funcionan las espadas
matademonios y erradicamagia.
Tu m’as montré
l’étendue des pouvoirs
Ho già visto i poteri della Spada Fendi-Demoni 
e della Spada Annienta-Demoni.
Agora vi os poderes da Espada Matadora de
Demônios e da Espada Destruidora de Demônios.
Я уже видел силу двух твоих мечей:
Разрубающего зло и Губящего зло.
