In the middle of his match with Maria Tsukimi, Takumi runs into (and almost over) Taro, a jaded player who's more into napping than fighting. But he's another Raikoo master, and when he wakes up, he's unstoppable! Then a hacker takes over the D.D. system to reshuffle Earth and Rikyu--and reality itself! As humans vanish into Rikyu and dragons soar through the skies of Earth, Takumi races to find the programmer who can stop the worlds from colliding.
