Chapter 314

The Mass (集合体) is the 314th Page of Yūki Tabata's Black Clover.

Summary
The Resistance members watch in awe as Mereoleona Vermillion with her Hellfire Incarnate, which grows in power the longer it is used, overpowers the demon and destroys its head and shoulders. She then joins the Spirit Guardians and Resistance at the castle's front gate where another horde of devils is emerging.

Nozel Silva, Langris Vaude, and Patolli reach the ritual chamber. While Dorothy Unsworth compliments the Black Bulls, they float over on a cotton platform to where Yami Sukehiro and William Vangeance are imprisoned. However, Lucifero uses the last of Moris Libardirt's magic and life to accelerate the ritual, causing the second gate to open. As the devils pour out of the gate, Lucifero uses his power of controlling lower ranked devils to merge the devils into one monstrous body. The mass of devils also swallows the coffins holding Yami and William. The mages outside watch in horror as the mass of bodies bursts out of the castle. Lucifero manifests himself in the monster and breaks apart the castle. When his Gravity Magic presses down everyone in the surrounding area, Albert and Floga recognize that it is Lucifero.

The Black Bulls then combine their skills: Henry Legolant begins manipulating parts of the castle, Vanessa Enoteca uses Rouge to protect the squad and base, Charmy Pappitson serves food from Sheep Cook: Master Chef, Gauche Adlai uses the magic stored in his left eye to multiply Grey who transmutes pieces of the castle into the magic house for Henry, and Gordon Agrippa continues helping with Henry's curse. Henry absorbs more magic power and uses it and the transmuted castle pieces to transform the base into the Ultra Giant Bull. The base then punches Lucifero while the squad yells for the devil to leave.
