Months after arriving at the Heart Kingdom, Asta still doesn't have any magic, but he's become more powerful at an alarming speed due to his training with the Spirit Guardians. Anti-magic is one of the magic attributes that falls into the "Arcane Stage" and is needed to defeat the devil. And because of that, Gaja asks Asta how exactly he obtained the five-leaf grimoire...
Nero used her Sealing Magic
 to seal the damage I took.
كانت نيرو قد استعملت سحر الختم
.خاصتها لختم الضرر الذي تلقيته
Nero versiegelte mit ihrer Siegelmagie
meine erlittenen Verletzungen.
Nero selló el daño que recibí
con su Magia de Sellado.
Nero selló el daño que recibí
con su Magia de Sellado.
Nero a aussi scellé mes blessures
grâce à sa magie.
Nero aveva usato la sua Magia di Sigillo 
per richiudere le mie ferite.
A Nero usou sua Magia Seladora
para selar meus danos.
И Неро тоже…
с помощью магии печатей закрыла мои раны!
