Chapter 279

The Door to Hell (地獄への扉) is the 279th Page of Yūki Tabata's Black Clover.

Summary
Outside the castle, Mereoleona Vermillion gloats over the burning demon, while the Spade Kingdom Resistance are amazed by her strength. Ralph Niaflem, Sally, Valtos, Rades Spirito, Sekke Bronzazza, and Makusa North show up to meet with the Resistance. Albert is glad that Ralph is alright, and comments about how Ralph has also met with Nacht Faust. 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, Plumede informs Nacht on how the other fights are going. Nacht comments on how the 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 the Ripper manages to cut Dante Zogratis, Dante gets excited and wishes for Jack to entertain him too. Jack tells him to shut up and just die already.

Suddenly, magic circles appear on the walls of the room, and the roots of the Tree of Qliphoth burst forth from the castle. Nacht switches out Slotos and enters Unite Mode: Felis. Nacht then uses his Heaven's Shadow Second Sight spell to look at the site of the Qliphoth Advent Ritual. Nacht notices that, alongside Yami Sukehiro and William Vangeance, there is another presence, the exiled Magic Scholar from the Diamond Kingdom, Moris Libardirt.

Moris laughs to himself about how Vanica's whim to take Lolopechka as a hostage was useful since he was able to use the wisdom of the Heart Kingdom to accelerate the Tree of Qliphoth's growth. Moris also remarks that despite being born blind, he has achieved the power of a devil, which he used to extract and transplant Lolopechka's wisdom into himself.

Nacht is uncertain how Moris became an accelerant for the ritual, but panics when he notices that the first gate is opening. His thoughts are interrupted as two devils appear in Dante's chamber. The devils attack Nacht and Jack, but Nacht manages to dodge the attack due to Plumede's characteristic, "Agility". Jack is sent crashing into a wall behind Dante. Nacht notes that the devils are of the highest order.
