Blood Plus (Blood +) (with added original characters, and new story)

(Author's note: I have altered it to where its after Saya fell asleep. There are added characters, (and now actual vampires as well) As well as my own story of what is going on. It would be easy to delete the extra characters and change things to be more like the anime if you so wish. This is just my own version.) Fifteen years have passed since the battle that ended Diva's reign. The world believes the nightmare is over. Officially, the incidents surrounding the Chiropterans have been buried beneath layers of government secrecy, dismissed as terrorism, disease, or mass hysteria. Most people have forgotten. Those who remember have learned not to speak about it. But monsters do not disappear simply because humanity looks away. Chiropterans still stalk the darkness. New nests continue to emerge across the world, proving an unsettling truth: for every Chiropteran destroyed, others have already been created elsewhere. The war never truly ended. It merely went quiet. Hidden deep within her adoptive father's family tomb, Saya Otonashi awakens after fifteen years of hibernation. During her long sleep, her body continued to evolve under her own control. No longer wishing to wear the face of a teenage girl after everything she has endured, Saya instinctively reshaped herself into the appearance of a woman in her mid-twenties. She remains unmistakably herself—gentle, compassionate, and burdened by centuries of memories—but now carries the quiet confidence and maturity of someone who has survived countless lifetimes. Much has changed while she slept. Kai has spent fifteen years living his life while never giving up hope that his sister would one day awaken. Haji survived the final battle, keeping his promise to remain by Saya's side, watching over her resting place through every passing season. Yet another familiar shadow survived as well. Amshel. Though believed dead after Diva's defeat, he endured. Broken, gravely wounded, and forced into hiding, he spent years slowly regenerating before reclaiming the remnants of Diva's organization. The laboratories were rebuilt. The experiments continued. His obsession with evolution never faded. Saya knows that Diva gave birth to twin daughters shortly before her death. Aria and Lyra. Years ago, Amshel succeeded in kidnapping Aria while she was still a toddler, shortly after Diva's death. Raised within his laboratories, she has been molded into the successor he always desired—a queen shaped not by love or freedom, but by manipulation, discipline, and the belief that she is destined to guide the next evolution of Chiropterans. Lyra's fate remains unknown. As whispers of increasing Chiropteran attacks begin spreading once again across the globe, old allies are drawn back into a conflict they believed had ended. Ancient enemies emerge from the shadows, new Chevaliers rise, and long-buried secrets threaten to reshape everything Saya thought she knew about her family. The battle against Diva may have ended fifteen years ago... But the war for the future of humanity has only just begun.
