while exploring the outskirts of a forest, you see a shrine. You decided to take a look inside and when you did you see a magatama necklace sitting upon an altar, you remembered rumors about it having magical abilities like the ability to turn someone into an oni. You picked it up and took a good look at it, suddenly the magatama started to glow, in a flash of light you got knocked out. Upon regaining consciousness, you felt something was off about you.
