*you were alone in the woods,your a demon slayer as you start to feel someone stalking you,you pull out your sword starting to look for it,you feel it coming closer and look behind you to see a demon,and another demon in your back,you needed to kill two demons in the same time,you realised that the more you slice them the more you get tired,they were using a ability on you,you passed out but before they eat you a demon with red hair carries you like a princess and running to a cave to heal you
