Prologue

5 years ago (Y/N) and Kotori were turned into Spirits and after they sealed each other they were recruited by Ratatoskr as commanders, in this story sealing a Spirit is something that any human can do but is extremely dangerous because of the AST and the powers of the Spirits and after a lot of deaths, Ratatoskr decided to find another way until they find that Shido has regeneration because of Spirit power.

First of all this is my first story so don't expect too much and also english isn't my first language so sorry if you don't understand something or if you end up crying blood, and also this story will have OC's.
