Summary
Outside the castle, Meleoreona incinerates the demon and wonders if that is all its got. The Spade Kingdom Resistance are amazed about how Meleoreona was able to defeat the demon. Suddenly Ralph shows up with Sally, Valtos, Rades, Sekke, and Makusa, to meet with Albert of the resistance. Albert is glad that Ralph is alright, but notices that devil on Ralph's shoulder and comments about how Ralph has met with Nacht. Ralph tells Albert that he has met Yuno, and how Yuno is a skilled Wind Mage. Ralph also describes how Yuno looks like Lady Ciel and has the strong heart like Lord Loyce. Albert hears this and thinks about how they can win with the help of Master Yuno and the others.

Inside the castle, Nacht is informed by Plumede about how the other fights are going. Nacht comments about how their kingdom's strongest magic knights are stronger than he anticipated, and thinks about how they still have time before the gate to the underworld is opened. As Jack manages to cut Dante, Dante gets excited and comments about how Jack will entertain him too. Jack tells him to shut up and just die already.

Suddenly everyone feels a presence, and everyone in and around the castle notices the Qliphoth roots appearing around the castle. Nacht switches Plumede and enters the Union Mode: Felis. Nacht then uses his Heaven's Shadow Second Sight spell to look at the site of the Advent of Qliphoth. Nacht notices that their is another presence at the site besides Yami and William, and notices that its the exiled magic scholar from the Diamond Kingdom, Morris.

At the Advent of Qliphoth's site, Morris comments about how Vanica's eccentrics was useful since he was able to use the wisdom of the Heart Kingdom to accelerate the Tree of Qliphoth's growth. Morris also comments about how in exchange for being born blind, he was blessed with the abilities of a Devil Host. Morris thinks about how the power of a Devil, made is possible for his magic to extract and transplant Lolopechka's wisdom.

Nacht thinks about how he doesn't know how its being done, but Morris is acting as an accelerant for the gate. Nacht notices that the gate is being opened, and thinks about how they have to eliminate Morris. Suddenly two devils appear before Jack and Nacht, which the devils manages to hit Jack but Nacht manages to dodge the attack. Nacht manages to dodge because of Felis's characteristic: Agility, and thinks about how the devils are of the highest order. The Devil's comment about how they are having fun even through one missed his target while the other one managed to hit theirs.
