Great Call of All Realms

It's a chaotic world. . . People here can awaken every time they reach the age of twelve, and we call them "spiritual callers." And what is summoned, we call it spirit. The summoned spirit can be a character in an anime or a novel. Bai Feiyun, a cold and handsome young man, look at how he dominates the world here, covering the sky with one hand! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
