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.
Then why not try using mana 
words as your heart desires?
لمَ لا تحاول استعمال كلمات المانا كما تشاء؟
Wie wäre es denn, wenn du versuchen würdest,
nach Herzenslust magische Wörter zu verwenden?
Entonces libéralo usando magivocablos.
Entonces, libéralo usando magivocablos.
Et si tu profitais de cette inspiration
pour utiliser les runes ?
Allora perché non provi a lasciar uscire 
le rune di mana che hai dentro di te?
Então, por que não tentar usar palavras
espirituais como seu coração mandar?
Тогда… попробуй и ты создать
 руны, какие душе угодно!
