Ifrit

In the story, Eggman Nega (once again disguised as Eggman), finds a book, explaining the Ifrit's ultimate power. It describes how it lives in an alternate dimension, and how it feeds on Chao, making it stronger. In Sonic's/Tails' story, they pick up pages of the book that were found lying on the ground, as they try to uncover everything. In Knuckles'/Rouge's story, they are simply looking for the Master Emerald, which Knuckles has once again lost. In Shadow's/Metal Sonic's story, they are trying to stop Eggman Nega from unleashing all of the power upon the world. In Silver's/Espio's story, the Chao and Team Chaotix go missing, as they try to discover what happened, and thus save them.
