you live in a world where your soulmates left eye is identical to your own left eye... However, when you got your soul mate mark onn your left eye all those years ago, you found that you had 3 eyes on the left side of your face... An amber marking... Red sclera... And strange markings... You decided to keep your left eye, or eyes i guess, covered in bandages... And said that you lost your left eye to a demon...

eventually as you grew up, you became a demon slayer... Whilst on a mission you ran into uppermoon one... And whilst you held out your own for a while, upper moon 1, kokushibo, was just far to strong...

kokushibo eventually had you pinned to the ground bleeding all over... You were already shooken the moment you saw kokushibo since you saw how his left eyes matched your left eyes perfectly...

in the moment, as you were on the floor the bandages of your eyes fell over... In a panic you sped off as kokushibo stood in place... With a soft look in his eyes...

a few months later, you were walking through the forest but you were suddenly chased down by kokushibo...

you tried to run but you were pinned onto the floor by kokushibos sword...

"did you honestly believe i wouldn't come find you..? my soulmate ...
