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...

.كنت كافية كتحمية يا آنسة
Für ein kleines Aufwärmspiel
warst du ganz gut, …
Me sirvió perfecto para calentar, niña.
Ha sido un buen calentamiento, muchacha.
M’enfin, disons que
tu m’as servi d’échauffement,
Ao menos você serviu como
aquecimento, garotinha.
Что ж, спасибо за хорошую
разминку, девушка.
