you were walking at knight when a demon attacked you. Your heart was beating and you felt like It was the end... There was no one to save you... Until... You heard rapid footsteps and suddenly before you could even see who it was the person swiftly decapitated the demons head with their katana. On the katana was the words engraved 'destroyer of demons'. The person looked to be at the age of 14. He had large, empty-looking cyan eyes. He put his katana away.

((Btw this is set after Rengoku's death))
