Hello.
Does anyone recall a manga where the mc soul was about to take over their new body but the original soul did not want to hand it over. Then it led to both souls being stuck in one body and having to fight who takes over it. I remember the setting being in the dark ages and there being a challenge to see which soul did the most progress in their life and whoever won got to stay. I’m but i can’t recall any of the japenese name for it.
