The XD Tournament (or "Xuan Dou Tournament") was a fighting event opened by the Fung family in collaboration with SHINE, to choose the "King of Combat" between different martial arts.

It involves concerted fights between the participants, taking place around the world. Everything, from travel to foods are paid by the organizers and specific points are designated as stations of the tour, on which the fights will take place.

Numerous people from the CRD. LSAI and even of the Chinese army, along with SHINE and the Fungs themselves, are involved in the tournament to monitor the activities of the EVA and the rival organizations.

While its facade was the one of a martial arts tournament, Fung Family's actual intention is finding good candidates to submit for the Awakening experiments.

WARNING: Fan speculation starts here

Brazel and actual SHINE's plans, however, go a step further. They want to unleash the Second Impact and make the existing EVA Hybrids evolve into the next phase. That's probably the reason the SHINE Leader invited Yan for himself, as seen in the animated comic:
