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...
Since I couldn't use Mana Skin, 
a technique to envelop
بما أني لم أستطع استعمال تقنية غلاف المانا التي تحيط
Da ich meinen Körper
nicht per Mana Skin schützen kann,
No podía usar la Piel de Maná
para proteger mi cuerpo,
No podía usar la Piel de Maná
para proteger mi cuerpo,
Je pouvais pas utiliser le mana skin
pour protéger mon corps
Io non sono capace di usare il Mana Skin,
Como não consigo usar a Pele
de Mana, onde se envolve
Я не мог использовать Покров маны,
чтобы защитить тело от жары,
