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.
We may be Spirit Guardians, but we 
cannot make mana grow from nothing.
.قد نكون حراس أرواح، لكن لا يمكننا استخراج المانا من العدم
Auch wir Geisterwächter können
nichts wachsen lassen, wo nichts ist.
así que ni siquiera nosotros
podemos hacer que aumente.
así que ni siquiera nosotros
podemos hacer que aumente.
Tout gardiens que nous sommes,
nous n’accroîtrons pas un mana nul.
Pur essendo Guardiani degli Spiriti,
non possiamo far nascere il mana dove non ve n'è.
Somos Guardiões Espirituais, mas não
temos como fazer florescer mana do nada.
к сожалению, стражи духов 
тебе не помощники.
