The once-vibrant Estero Harbor now sleeps beneath emerald waters after the catastrophic rise of the Cube Miracle. In the haunting silence of submerged streets and forgotten memories, three Espers cross paths: Norah, whose voice can calm the sea; Anna, a color-blind painter reborn with Persephone’s light; and Li Guang, a fearless bounty hunter chasing adventure. As ruins are explored and lost summers remembered, music and art intertwine against the lingering shadows of the Miracle.
