Eternity Suspecting that someone helped the Mantis Void from before, Natsuko secretly follows Memmeln, knowing that she is part of a group of mages that were responsible for transforming the Mantis Void into a priest to make it destroy the Soul Future, but doesn't know their true goal. In the original storyline, the Ultimate Void appeared after Luke saw through the Mantis Void's disguise and slayed it, but it is revealed to be a transformed Memmeln. Luke tags along with her and she reveals Memmeln's secret. Following her and the elves from before to a secret cavern, they witness a cult performing a ritual (revealed to be the "choir" that Memmeln was attending) to awaken the Ultimate Void. When Unio arrives, Natsuko warns Luke against telling him to avoid panic and they leave afterwards...
