Asta and the others manage to meet with the queen of the Heart Kingdom, Loropechika, who had also been chosen by the water spirit, Undine. They are able to confirm that the devil’s curse that they spotted in the Heart Kingdom was originating from Loropechika herself and that the devil was in the Spade Kingdom. Meanwhile, Vanessa, Magna, and Luck went to investigate the Diamond Kingdom and find it in ruins after a single mage of the Spade Kingdom had annihilated them. In order to defeat this devil, Loropechika asks Asta and the others for their help…

The Magic Knight Squad Captains end up doing a team battle due to Julius’ suggestion. Since the citizens are still weary after the attack by the Eye of the Midnight Sun, they want to prove that they still mean to protect the kingdom and its citizens. The Magic Knights watch in anticipation as their captains split up into two teams and go all out in this battle.

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.

For some reason, Charmy, who had tagged along with Asta and the others to train in the Heart Kingdom, keeps trying to eat up all of the food in the Heart Kingdom. Asta tries to take her back and goes to the forest Charmy is last seen. However, Charmy had also trained with the Spirit Guardians and had become even more powerful. Meanwhile, Yuno is contacted by Sister Lily and heads back to his home village of Hage.

Grey reminisces on her past. Meanwhile the fight between Dante and Asta is continuing!

Yami strikes Dante what should have been a mortal blow, but he recovers quickly with the Power of his Devil. Asta witnesses his own Devil seethe in frenzy. In the Heart Kingdom, Charmy and Leo battle more Dark Disciples.

Yami and Vangeance are taken to the Spade Kingdom so that the ritual to open the gate to the underworld can begin. Despite how hurt he is, Asta tries to escape the infirmary to go and save Yami, however he is stopped by a mage named Nacht Faust, who also happens to be a devil-possessed. He offers to show Asta how to use his devil powers even better. Meanwhile, the Magic Knight Squad Captains hold an emergency meeting. The Golden Dawn has almost been completely annihilated, and Yuno shows up to the meeting, showing new resolve.
