Chapter 253 of Black Clover showcased the epic battle of Vanica against Lolopechka, Noelle, and Mimosa. Nero or Secre Swallowtail turned out to be the hidden trump card in the battle, and in the last page, she uses an extremely powerful spell.
Nero or Secre Swallowtail, an anti-bird is one of the magic knights of Clover kingdom. Nero uses sealing magic to open or close objects. Later she improves this ability to trap beings in objects. As she lived in the Heart kingdom for some time, she had learned their mana method and uses it in combination with her sealing magic.
In chapter 253, Nero uses this powerful combination of spells called Mana Method: Sealing Magic — Eternal Prison. Nero is an Arcane mage, and the Eternal Prison is a type of forbidden spell.
Through this particular power or spell, the user can create a cube of mana around the target and can trap them in it for centuries. This spell requires a high-level mage due to its magic power requirement.
Nero uses this spell in sync with Lolopechka’s Ludic Sanctuary, where Vanica is trapped in a whirlwind of water. Vanica kept charging at Noelle and got too immersed in toying with her.
Vanica increased her devil’s power usage to a maximum, 70%. This was the chance her opponents were waiting for as Nero burst out of her hiding place and used her sealing magic on Vanica.
One weakness of the Eternal Prison spell is that since it takes a lot of power, it needs some time to be fully formed. And thus, while the prison is being set, the target can attack from within with their own spells. This small weakness might become a huge opportunity for Vanica, who possesses the powers of Megicula.
The addition of Nero to the team of Lolopechka, Mimosa, and Noelle has of course, given them a better foothold to defeat Vanica, but the exact result of the battle is still unknown.
