Summary
Zenon Zogratis explains how demons are a miracle born from the human hatred and the power of the underworld. Zenon tells Yuno and Langris Vaude that long ago that there were two royal youths who had phenomenally strong magic within the Spade Kingdom, but at some point the two started to hate each other and became demons. The two had fought each other but were sealed away. Zenon explains that House Grinberryall was guarding the two ancient demons but the Dark Triad has woken them up and released them in order to distract them. Zenon then asks if the Clover Kingdom would be able to protect itself with so many of their mages here.

Outside of the Spade Castle, Mereoleona Vermillion notices that the demon she is facing magic has gotten stronger since it is absorbing mana through its wings. The demon then charges which Mereoleona prepares to continue to fight.

At the Clover Kingdom, Julius thinks about how he is no match again the demon with the way he is right now. Julius figures that he will need time to release his full power and thinks about how the others will have to hold on until he is done. Julius tells Damnatio Kira that he will need to use his power and apologizes since Damnatio is not a Magic Knight.

Outside the Clover Castle, the demon continues to head towards the castle while everyone runs away since the demon it to big to deal with. Suddenly Kaiser Granvorka and multiple member of the Purple Orca squad so up and attack the Demon. Kaiser uses his Area Helix spell to stop the demon, and tells his squad to not let the demon any farther. As Kaiser and the Purple Orca squad are slowing the demon down, The Blue Rose, Green Mantis, and Crimson Lions squad evacuate the citizens of the Royal Capital. While all this is happening, the king, Augustus Kira Clover the 13th, tells everyone to make the demon stop.

As the demon prepares to attack the castle, Kirsch Vermillion and Nebra Silva use their Magic Cherry Blossom Storm of Petals and Transient Illusion spell to block the Demon's sight. As the demon fires its blast, Solid Silva uses his Sea Serpent's Bellow spell to divert the blast, but is frustrated that that is all he is capable of, even after six months of training his magic. As the Magic Knights continue to attack the demon, they notice that the demon's magic is ludicrously strong. As the demon fires another blast, Damnatio suddenly appears and uses Scale Regulate spell on the blast but notices that the blast is to powerful to negate it completely. Damnatio thinks about how the only way to fight this phenomenal magic is to strike back with magic that is equally phenomenal, which the blast is suddenly stopped with a spell.

The people recognize the spell and notice Julius has arrives, in his adult body. As the people are glad to see the Magic Emperor, Julius thinks about how he was able to advance body by ten year but his time and abilities are limited. Julius and Damnatio then combine their magic to attack the demon, but Julius ends up reverting to his child for during the attack. Julius thinks about how he is out of time already and wonders why since it is to soon, while Damnatio thinks about how he cannot hold the demon at bay any longer. As the demon to prepares to fire a large blast, Asta suddenly shows up and enters Devil Union with Liebe.
