The one who saved Asta from the group calling themselves the Eye of the Midnight Sun was the Wizard King, Julius, who was waiting for them at their base. Asta and the members of the Eye of the Midnight Sun are in awe of Julius’s power.
The stronger you become, 
I'll get even stronger!
!مهما أصبحت قويًّا، سأصبح أقوى من ذلك
Wenn du stärker wirst,

Si tú te fortaleces,
yo también puedo hacerlo.
Si tu deviens plus balèze,
alors je le serai encore plus !
Tu potrai anche diventare più forte,
ma io lo diventerò ancora più di te!
Quanto mais forte você ficar,
mais forte eu vou ficar!
