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...
if I used the ki technique
 I learned from Captain Yami,
،أنّي إن استعملت تقنية الكي التي تعلّمتها من القائد يامي
Wenn ich das Ki, von dem Ordensführer
Yami mir erzählt hatte, nutze,
En pratiquant le ki
transmis par Yami,
che usando il ki che avevo imparato
 dal comandante Yami
que, se eu usasse o ki que
o Capitão Yami me ensinou,
С помощью ки, которому обучил капитан,
я мог усилить антимагию, текущую в теле!
