Chapter Summaries

As the GX Tournament began, Duel Academy students overwhelmed the Society of Light with bizarre and ruthless tactics. After seeing the Society’s members beaten into disarray, Mina told Kira that his “Underworld Plan” had been named too conservatively.

• Mina reviewed the first day’s results and told Kira that his Underworld Plan’s name had been too conservative.

Kira confirmed that his elite Duel Academy team had handled the Society of Light’s first assault and turned his attention to the upcoming Professional League World Champion Tournament. Meanwhile, D.D. gave in to the dark power of a card he had hidden for ten years and prepared to reclaim Ultimate D’s remaining strength.

At the World Champion Tournament, Dr. Collector faced D.D. in a televised duel while Kira watched with Judai and his friends.
