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...
That's the spirit. 
Don't think, just come at me!
!تلك هي الرّوح المطلوبة. لا تفكّر، هاجمني فحسب
Genau so. Stürz dich
ohne Zögern auf mich!
Así se hace. ¡Dalo todo sin pensar!
Así se hace. ¡Dalo todo sin pensar!
C’est ça que tu dois faire.
Attaquer sans te retenir !
É assim mesmo! Não pense em
nada, apenas me enfrente!
А теперь сражайся
и со мной с таким настроем.
