Thirteen-year-old Kai Ember's life revolves around protecting his five-year-old sister, Hanabi, in a world where powerful guilds and dangerous creatures reign supreme. Abandoned by their parents, the siblings navigate a perilous existence, living in a rented storage room and relying on Kai's odd jobs to survive. However, Kai's life takes a dramatic turn when a vivid dream grants him the knowledge of a tragic future where he is both an author and a victim in a world eerily similar to his own. As Kai awakens with newfound abilities and memories from a past life, he embarks on a journey to reshape his destiny. Discovering he is the Progenitor of Vampires, Kai gains extraordinary powers, including enhanced strength, regeneration, and blood magic. [Can't find any similar novel like The Novel's Extra so I'm making one. Even though I'm taking inspiration from it, after the early chapters, the change will be noticeable.]
