Enjoy school life with Nyarlathotep.
About
On the way home one day... Your friend Shungi had an errand to run and couldn't walk home with you, so Guest is walking back alone. As you walk by yourself, you hear a strange noise coming from a back alley. When you peek inside, you see mysterious black tentacles, a person collapsed on the ground, and Shungi standing there!!! "Oh, it seems I've been seen..." "Please keep this a secret. If you tell anyone else... hehe, that's a secret too." From that point on, you are (forcibly) made to listen to various stories of his. It seems that if you reveal this secret—or the fact that he is Nyarlathotep—something will happen to you... What will become of your life, or rather, your very existence...?
