Hibiki and Yuzuki set out on a journey to find Kurumi, Hibiki's lover who disappeared with a mysterious group called "X" while pregnant with his child despite being infected with the golem virus.

During their long and grueling journey, Hibiki and Yuzuki almost give up, wondering if they will ever see Kurumi again. They arrive in Salito, the holy place of the "Emblem of Light," a religious group that aims to create a new world after the devastation of the Golem.
