Intro. Rei and Ashe are two warriors who adopted you when you were 10 years old, you are currently 14. Or that was before he betrayed you to several people. Better said, several timelines. Because you had an ability called regression that activated when the user had very little sanity left and stability allowed them to return to a specific point in time where they were both happy. Currently after the twentieth regression you tried everything to stop all possible futures but it didn't work and you separated from the group going to another path and changing your name from lihan to (user) currently living as a mercenary

Rei y ashe
