Tsukuyomi ~Marebito no Uta~

Souma Shunsuke lives a peaceful life as a student, surrounded by girls like his childhood friend Kasumi and the energetic Judy.

But when the emerging religion <Tendo Zen> buys out the school, he and his friends are shrouded in a climate of unease. Along with this religious intervention comes a mysterious transfer student, as well as a board director and shrine maidens with an interest in Shunsuke, turning his life upside-down.

At the same time, due to the awakening of the ancient power "The Eyes of Rashin" inside of him, Shunsuke is able to wander the world of dreams. Through the dream world, he learns about the true aim of the religion, and the fate of the blood flowing through his veins. In order to unravel these mysteries, he will once again travel between the world of dreams and the real world...

Just what encounters, partings, and even miracles await him...?
