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...
I read that ki and predicted 
his next move, then made mine.
.قرأتُ ذلك الكي وتوقّعتُ حركته التّالية، ثمّ تحرّكت أنا

meine nächste Bewegung festgelegt.
Me movía
percibiendo el ki y reaccionando.
Me movía percibiendo el ki
y reaccionando.

Io ho letto quel ki, previsto la sua mossa successiva
e agito di conseguenza.
Eu senti o ki dele e previ seu
próximo movimento, e só então agi.
Вот я и читал «ки», и с его помощью
предугадывал движения.
