With the emergence of the pillars of light come shocking discoveries! Miharu, Haruto’s beloved childhood friend from Rio’s past life, is among the people he rescues—and that’s not all. Rio then learns of a sacred prophecy that connects the pillars to the arrival of six heroes, two of whom may well be Miharu’s missing companions.
