Asta and the other Magic Knights chosen to train in the Heart Kingdom are joined by Magna and they finally start their training under Loropechika and the Spirit Guardians of Lightning, Earth, Plants, Fire, and Wind and Undine. Since Asta has no magic to begin with, he ends up sparring with Gaja, the Spirit Guardian of Lighting.  They Magic Knights all work harder to surpass their limits.
So the Spirit Guardians won't break 
even if I go all-out, right?
لن ينكسر حراس الأرواح إذًا حتّى وإن بذلنا كل ما لدينا، صحيح؟
Die Geisterwächter werden nicht schlappmachen,
wenn wir Ernst machen, oder?
Ces gardiens de l’esprit supporteront
qu’on y aille franco ?
Quindi posso andarci giù pesante,
tanto i Guardiani degli Spiriti non si rompono?
Então, os Guardiões Espirituais não
vão cair mesmo se eu cair matando?
Стражей духов ведь 
даже в полную силу не сломать?
