After the sudden departure of a valuable friend, the future of Team Blackout is now uncertain. Yu-yu Kondou and Megumi Ookura feel frustrated for failing to prevent the inevitable, while the heavily involved Touya Ebata is trying his best to atone for past mistakes that led to this misfortune.

Danji, who had arrived earlier in America to look into the background of the Deluxe tournament at Michiru’s behest, begins to suspect a connection with the case of the missing fighters. Meanwhile, a new force emerges in Japan, with their ideal of achieving the “Ultimate Fight” in cardfights. What is their goal of recruiting more and more fighters?
