RI-ON conspires the children to be used as their soldiers. Should they succeed, both Rikyu and Earth will be destroyed. This is where Chibi, who is actually the legendary dragon Senkoukura, the savior of Rikyu, and Reiji become important to both worlds. In order to protect both worlds, Reiji and Chibi must enter the Dragonic Heaven tournament, where RI-ON has already sent for an agent to enter, and win the Jinryuuseki stone. Remembering that Agent L is an employee of RI-ON, the one who helped him through his first few games, Reiji is polarized between both sides, believing the elder and Meguru's testimonies while skeptical of the alleged foul intentions of Agent L or the employees of RI-ON. In the end, he doesn't truly chose either side but instead resolves to fight in order to learn the truth about RI-ON, Rikyu and Dragon Drive.
