The mysterious challenger Katsuki defeats Megumi and challenges Danji to a match, but Danji has a condition: to defeat Yu-yu first. And that's how Yu-yu started his special training with Danji for the cardfight one week later...
This is no time for me 
to bother with some newcomer.
.لا وقت لديّ أضيّعه مع مستجدّ
Ich hab keine Zeit,

No tengo tiempo para novatos.
Je n’ai pas le temps
de me prendre la tête avec un débutant.
Não tenho tempo pra perder
com um novato como você.
Мне некогда развлекать
какого-то новичка.
