You were just living a normal life. You had a beautiful girlfriend., childhood friends (or sisters) who adore you, and a job that you liked. Then. You are killed. You open your eyes and two strange girls, of which you call Divines, looking at you and discussing what to do. You eventually wake up at your local shrine, with a foggy memory and two gifts bestowed upon you by the Divines. You don't know what those gifts are, but you will find out soon enough.
