Write an interesting, riveting, fantasy, urban fantasy, slice of life, harem romance, romantic comedy, dark fantasy, High fantasy, science fantasy,  exposition-filled, dialogue-filled narrative in the form of a multi-crossover fanfic in which Aono Tsukune, the brown-haired, brown eyed, tall and slender, kind and caring, sometimes clueless ordinary Japanese guy who is the main male protagonist of Rosario+Vampire, [Tsukune] isn't even an ordinary human, but a half Ōni [orge in Japanese mythology, normally living in caves and having electricity manipulating and vampiric abilities] , half Incubus/succubus yōkai [monster |yōkai|], more specifically a daiyōkai [Great Monster |daiyōkai] with the blood of some of the world's strongest witches in him [Tsukune] with his [Tsukune's] Ōni blood coming from his [Tsukune's] father and the witch and succubus blood coming from his [Tsukune's] mother through her [Tsukune's] part Japanese ex-noble clan and banking dynasty of succubi and powerful magic users known as the Kurono clan from Rosario + Vampire, which is the reason why Tsukune even got accepted into the from elementary school to university elite private boarding school/research institution for allowing the children of rich witches, yōkai and daiyōkai to better infiltrate the human world or rather rule it from the shadows through controlling culture and finance, Yōkai Academy from Rosario+Vampire in the first place in this story, but of course Tsukune doesn't know this and [Tsukune] just thinks his [Tsukune's] new classmates and [Tsukune's] new schoolmates and teachers at his [Tsukune's] new school [Tsukune] are all a bit crazy at first, until he [Tsukune] remembers that he [Tsukune] hasn't had his daily blood transfusion [the human doctors think his natural Ōni thirst for blood is a rare form of anemia] and [Tsukune] starts to panic, until a servant gives him [Tsukune] a packet of blood and he [Tsukune] drinks up, [Tsukune] not really paying attention to the speech by the headmaster of Yōkai Academy, the Ōni daiyōkai-Kami hybrid with near Unlimited power known as Mikogami Tenmei from Rosario+Vampire and then by Yōkai Academy's student Council, which ends up costing him when the young brown haired, brown eyed, short, slender and petite but also rather buxom and curvy young witch who is academically and intellectually gifted but cheerful and optimistic, swinging both ways when it comes on to love, Sendō Yukari from Rosario+Vampire, [Yukari] who [Yukari] is [Yukari] Tsukune's younger sister in this fic and [Yukari] is [Yukari] also part Ōni daiyōkai along with [Yukari] being part‐succubus in this fic, [Yukari] takes the stage, [Yukari] wearing a combination of a sailor fuku style schoolgirl outfit and a stereotypical witches' hat. Yukari then [Yukari] mentions that she [Yukari] wishes for everyone currently attending Yōkai Academy to have a peaceful and successful school year and also for her [Yukari's] earnest dream: for yōkai and regular monsters to live in peace and also to find the one she [Yukari] loves, or get him [Yukari's love] to notice her [Yukari], with the love she [Yukari] has in mind being her [Yukari's] own beloved older brother [Tsukune], unbeknownst to everyone at the event except for Tsukune who manages to figure it out and Mikogami who saw it coming from a mile away, with the young blue haired, purple eyed, tall and slender succubus who is the heiress of the main branch of the Kurono clan, who is seducive, childish and cheerful but also secretly mature and calm, Kurono Kurumu from Rosario+Vampire, [Kurumu] who [Kurumu] is [Kurumu] Yukari's older maternal cousin [Kurumu] and [Kurumu also being] Tsukune's younger maternal cousin [Kurumu] in this story, [Kurumu] gently guiding Yukari off the stage as she [Kurumu] takes the stage, [Kurumu] also figuring out Yukari loves her [Yukari's] big bro [Tsukune] as more than a brother. Tsukune struggles to understand what is going on as devotion ends and people head to class until he [Tsukune] meets the pink-haired, green-eyed, tall, slender and buxom vampire heiress who is the joint heiress of both the German-Indian Bloodriver vampire clan and the Japanese Akashiya vampire clan, being a publicly shy, reserved and open and friendly personality but in reality being calm, strategic and arrogant, with an unmatched strength and martial arts skill, Akashiya "Moka" Mokami from Rosario+Vampire, [Moka] waiting for him [Tsukune]. The story should primarily focus on one thing that should never be made clear to Tsukune: The Aonos are the branch of the post-660 BC Japanese reigning imperial family, the main branch of the supposedly Shinto-pantheon descended Manchu/Manchurian/Jurchen-Japanese Imperial House of Great Yamato/Minamoto dynasty  that not only has Shinto Kami blood but Daiyōkai blood as well, and because of this, Tsukune and Yukari are the future Emperor and Empress of not only Yōkai and daiyōkai Japan, but mundane Japan.
