[Anime Crossover] The Demon King Savior

Originally titled Anime Crossover: Even Today, I Struggle Between Saving the World and Destroying It. My name is Yuan Shiliuye, and I am the future head of the Yuan family. Before I could even become head of the Yuan family, the burden of supporting dozens of sword men landed on my shoulders, forcing me to find a job at a young age just to keep the family fed. My mother was a former savior, and my father was a former great demon king. Their careers are hereditary and come with excellent benefits. Their subordinates all hope I will inherit their respective bosses' positions, so I found myself unable to choose a career. But before I could decide what I wanted to do in the future, I suddenly discovered that both the savior and the great demon king bent on destroying the world had already been replaced! I hadn't even started the job, and I was unemployed!!! In this age of a rapidly growing population and fierce competition for jobs, even saviors and demon kings have to compete for their positions. Considering the pressure of finding work, the subordinates on both sides began diligently offering me advice. But after being raised into a useless homebody by my blade spirits, all I wanted was to lounge around until I died. A mature blade spirit needs to learn to live independently. And while you're at it, please remember to feed your underage master. Thanks. Then one of my father's unscrupulous subordinates dumped me in another world. Some unscrupulous jerk: If there's no position available, you can start your own business. Please stop living off your parents. And so I was forced into a career internship (crossed out), and a life of getting beaten up by society. As a weakling who couldn't win a fight, I had no choice but to cling to a few temporary guardians if I wanted to survive in these perilous worlds. Then I got carried away. I once danced with demons in Heian-kyo, where humans and spirits lived side by side; wreaked havoc in war-torn Sicily; swaggered around night-shrouded London; threw my weight around in nuclear-peace-loving Yokohama; ran wild in peaceful, tranquil Namimori; and ruled the roost at a strange, fantastical academy for those with special abilities... I once picked a fight with the strongest onmyoji in history, plucked the hair off the black mud of humanity, flirted with Arakabuto, pestered a blond criminal consultant, gave the first Vongola boss a hard time, and ambushed the heir to the Vongola family. It was fun, but during that time I had to earn spiritual power to support the family, sleeping later than a dog and getting up earlier than a chicken. It was a life no human should have to live. After I finally made it back, having gone through countless hardships, people from both sides cornered me at my front door again. All the subordinates: Have you decided yet?! I clutched my frail, innocent, helpless self in terror. Please, leave me alone! Isn't it great to lie around at home and let other people take care of me?! Short extra: After returning to the normal timeline, I discovered that my guardians (as they called themselves) from all those different timelines had shown up too. And they were fighting over my custody... I mean, who got to raise me (?!) A certain First King: ...I seem to remember her documents say her surname is Weizmann. A certain blond criminal mastermind: No, you've got it wrong. Her surname is Moriarty. A certain seafood company founder: Wasn't her original surname Vongola?! A certain great onmyoji: No, it was Abe at first. Then the former guardians all turned to look at me. Me: ... Why do other people's love triangles involve everyone fighting to be someone's husband, while yours involve everyone fighting to be my dad? You're looking for Noa Weizmann/Claire Vongola/Cloris Moriarty/Kamitsuki Yuan (Abe). What does any of that have to do with me, Yuan Shiliuye!!! Planned arcs: The Genji arc (Abe no Seimei and Minamoto no Yorimitsu) The Sicily arc (the first Vongola boss and his Guardians) The British arc (the three Moriarty brothers and the consulting detective) The Yokohama arc (the Bandage-Wasting Device and the Songstress of Yokohama) The Tokyo arc (the Kings and the yokai) The Namimori arc (the tenth Vongola boss and his Guardians) Original Academy arc (the strange everyday life of an academy for those with special abilities) Note: The main story is told in first person. The heroine is not human (literally). Because of her parents, her bloodline is a mixture, and the timelines within her are a mess. Although she is seven at the start, that is only conceptually. By the timeline of the real world, she is over a hundred years old. The heroine grows stronger over time. She is weak at first, but will become very powerful later. She loves causing trouble early on. She mellows out later, but still causes trouble. This is a beloved-by-all story. The heroine is mischievous, shameless, and loves causing trouble, but she is still everyone's darling. There are both familial and romantic storylines, but not too much romance, and mostly in the later chapters. If this isn't for you, please don't read it. The author is sensitive, so no fighting or unsolicited advice. Thank you for understanding~ Theme: The everyday life of an unconventional savior. Even in the darkness, she still faces the light.
