Natsua Aika, a 14 year old boy from England has sadly passed away. But that's not the end of his story, he's been reincarnated into the world of demon slayer as a small cat. Follow Natsua on his journey in the world of demon slayer in a new body. (Yes I know this is one of those cringe oc inserts but bear with me here.) Cover does not belong to me. I do not own demon slayer! This story has spoilers for demon slayer season 1.
