Of the Red, the Light, and the Ayakashi

In the curious town of Utsuwa, where spirits known as ayakashi roam, lives Yue, a sheltered boy born and raised at the local shrine. On the night of the winter festival, Yue descends the mountain for the first time and encounters two boys. Though Yue wants nothing more than to become friends with his new acquaintances, Mikoto, the master of the shrine who rules over Utsuwa, declares that Yue must choose one of the boys as his "Meal"! Faced with this incomprehensible decision, what will Yue do?!
