Cardfight!! Vanguard overDress

Unable to cope with his unique abilities, Yu-yu Kondo runs away from home. He is brought to an abandoned amusement park and discovers Vanguard.

Danji senses Yu-yu's interest in Vanguard, and allows him to choose a card to be his buddy; Megumi misunderstands Danji and Yu-yu's relationship, and challenges Yu-yu to a cardfight.

The mysterious Katsuki challenges Danji to a match, but Danji has one condition: to defeat Yu-yu first. Yu-yu begins his special training with Danji.

The morning after the sudden retirement announcement, the amusement park receives notices for destruction. Danji goes missing, leaving Yu-yu and the remaining Blackout members troubled.

Danji joins the town's Pro-Wrestler Association as a regular in order to revive it, and is shocked to learn that his opponent is Hiroshi.

Tohya arrives at Wonder Hill once more, hoping to have another match against Danji. However, Danji hasn't sufficiently recovered from his injuries so Yu-yu challenges Tohya in Danji's place.
