Months after arriving at the Heart Kingdom, Asta still doesn't have any magic, but he's become more powerful at an alarming speed due to his training with the Spirit Guardians.

but I will train with you 
until you are satisfied today.

hasta que estés satisfecho.
pero entrenaré contigo
hasta que estés satisfecho.

mas vou treinar com você até
que você se dê por satisfeito.
но сегодня мы будем сражаться до тех пор,
пока ты сам не захочешь прекратить.
