The Supernatural Revival Began, but I Became an Urban Legend

In Ninomiyashi, there is a widely circulated urban legend:

When you encounter something beyond your knowledge or comprehension, blow the Death-Calling Whistle.

The creature of the night, the messenger of death, will answer your call and come to claim its offering.

But remember, never blow it for no reason. A furious god, unable to find an offering, will take your soul.

An Jiang, Urban Legend, Yelan: I just wanted to do the right thing and beat up the jerk who made a false emergency call. How did the story get so creepy?

Please Note:

1. This is an atypical supernatural resurgence story, with many original additions.

2. The story is set in Japan. If that bothers you, please move along.

3. Yuri, yuri, yuri. But even if you don't like yuri, you can still read it. The romance is sparse.

4. Mild horror.
