Mio Lady Mio is a metaphysical being seeming to be made of pure light that appears at the end of " Final Fantasy Crystal Chronicles " . Her existence is tied to that of the Meteor Parasite in Mount Vellenge . Story . Early History . Most of Lady Mio ' s history is unclear , and the girl ' s very existence is never revealed or even mentioned until the end of the game . What is known is that Mio was born , along with Raem , from the meteor impact that destroyed the Great Crystal and gave rise to the miasma produced by the Meteor Parasite . Both entities are apparently dependent on the memories of living beings for sustenance . However , their individual palates diverge quite significantly . Mio desires simply to " nibble on memories from time to time " , leading to forgetfulness , while Raem consumes all the memories which he perceives , thereby eradicating all coherent thought and recollection . Encounter . The Tipa Caravan ners meets her for the first time after their battle against the Meteor Parasite . Once defeated , the Meteor Parasite withers and lies weakly on the ground , waiting for someone to finish it off . Before the Caravanners can administer the final blow , a disembodied voice commands that they stop and a white light from the Crystal Chalice flashes , taking them to the Nest of Memories . This event is probably caused by Raem . Once there , the history and nature of Raem is revealed by Lady Mio , as is the fact that both Leon and Hurdy were victims of the being ' s insatiable appetite for painful memories . However , he was dissatisfied with them , as they spent all their time looking ahead and giving little thought to the past . While this information is being related , a series of randomly - determined questions pertaining to the Tipa Caravanners journey must be answered in order to progress . An incorrect response will cause the Caravanner to lose a memory , and will summon a pair of Raem ' s Minions . The game is over if their memory total is reduced to 10 or less . Conflict . Once all the questions are answered , Lady Mio opens a door , through which the Tipa Caravanners enter into a new area , which seems to be a force field high upon the Nest of Memories . Misleadingly , this area can be misunderstood as an area in the space high above the real world . In this moment Raem descends . He and Mio begin a discussion of the whys - and why - nots of consuming memories . As soon as Mio shatters the force field to rescue the player of the avaricious Raem , however , this facade quickly drops to reveal a brutal thug , using his immense power to pin her to the floor . Thus begins the final battle against Raem . Once defeated , Raem refuses to surrender , apparently afraid of fading away . In a desperate attempt to preserve his own existence , Raem uses his powers to both possess and merge with Lady Mio , becoming Memiroa , or just " Mio - Raem " ( " Memiroa " is an anagram of " Mio " and " Raem " ) . Once Memiroa is defeated , it shatters into thousands of shards and the voices of Mio tells the Tipa Caravanners that the two will sleep for a while . Then the Tipa Caravanners are teleported back into the cave of the Meteor Parasite , which needs one final hit to kill it .
