In an empty park, Meimi faces an abrupt assault from the demon Rococo, whose strike aims to draw out the hidden power of Misty Mei. At the same time, Naoto welcomes his stepsister Hikari home from overseas study, an arrival that stirs quiet unease in his girlfriend Rika as the two begin attending school together. When Misty Mei suddenly takes Rika away, the angel Luvriel appears with an urgent message: only a renewed bond between Naoto and Hikari can bring forth a new Jibril capable of saving her.
