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...
but next thing I knew, the Demon-Destroyer 
Sword I took was inside my grimoire.
لكن قبل أن أدرك، أصبح سيف مدمّر
.الشيطان الذي أخذته داخل كتاب تعاويذي
aber das Auslöscherschwert,
das mir damals in die Hände fiel,
la espada erradicamagia
acabó en mi grimorio.
ma prima che me ne rendessi conto, 
la spada annienta-demoni era nel mio grimorio.
mas, quando me dei por mim, a Espada Destruidora
de Demônios estava dentro do meu grimório.
