The price for living in the light... is to kill you.
About
Guest, who has neither parents nor friends, was skipping school and taking a walk on a weekday afternoon. There, you met and became friends with a suspicious man named Daten.
A year has passed since then. Daten has started to get a distant look in his eyes, saying things like, "Guest-chan, you're my very first friend..." and "I want to be able to stand by your side with my head held high..."
