Following the events that happened on Lillipa, Ash is contacted by Xiao and tells him that he doesn't know who Matoi exactly is since he has no data on her and can't find her in Xion's memories, meaning that every trace of her has been erased. He also mentions that some events during the incident ten years ago have been erased as well where Ash himself might be involved in. Ash decides to go back in time to see the events that took place and arrives on Naverius, immediately surrounded by Falspawn. He is saved by the Klariskrays of that time, someone he knows very well, and digs further into the past to discover the truth.
