Asta and the other Black Bulls are split up throughout the Underwater Temple due to Gifso’s magic. They are forced to go head-to-head with the temple mages in a battle royale.
your anti-magic sword is nothing 
more than a lump of iron!
!يصبح سيفك ملغي السّحر مجرّد كتلة من الحديد
ton épée d’anti-magie,
c’est qu’un tas de ferraille !
la tua spada anti-magia
è solo un grosso pezzo di ferro!
a sua espada antimagia não
passa de um amontoado de ferro.
