In an alternative universe, Norman a Professional Demon Slayer meets a girl her age who wants to be a Demon Slayer too because her Parents were killed by Isabella a Demon part of the 13 Chizuki. On the other hand, Ray a previous Demon Slayer is no more. He had been bitten by one and had been granted uncontrollable power. But he's been put under the custody of Anna a medic who has been trying to find an antidote. She just has to be careful things don't go out of hand. The original story setting goes to Kimetsu No Yaiba (Demon SLayer) I changed it up :) I like doing AU's Hehe
