Things escalate when Ooguro's assistant claims the planet fixated on him and is now barreling towards Earth. Panic grips the world as planet Remina approaches, turning adoration into animosity towards the Ooguros. Branded as the architects of doomsday, Remina becomes a target of a frenzied population as the ominous hellstar draws near.
