When her mom told her that her grandfather and her great uncle was coming to town; Marinette panicked. In fact, she had a full blown panic attack. There was no way she was going to get out of this.
Her mother didn’t speak too much to her father. They had a complicated relationship. Sabine had grown up in China with her mother, while her father resided near Japan, having been born and raised there, in a small country he ruled as king. Only demons resided there.
He had been a cold, stoic man with little interests in the affairs of humans. He certainly didn’t understand why his beloved daughter chose to be around them. However, he had been outright furious when he discovered Sabine had eloped with one and ran off to France. They didn’t speak for almost a decade.
The silence was only broken when Sabine told her Uncle that she was expecting a child. And half-human or not, Sesshōmaru would be there to welcome his grandchild into the pack. Inuyasha had tagged along to keep an eye on his older brother. Though the older Inu Daiyōkai may have become more tolerable of humans but that didn’t mean he didn’t still have few nasty streaks. Honestly, Inuyasha didn’t trust his brother not to just slaughter Tom Dupain as soon as he met him. The demon lord turned King would have to deal with the unfortunate tales of the Princess who ran off with the Baker; as if it was some foolish romantic tale.
Somehow, Sesshōmaru remained perfectly polite if more than just a bit standoffish. He outright glared at times. However, he remained in France for months while he waited for his grandchild to be born. Subtly hinting to his daughter, that it would be better to raise the pup among their own kind.
Then little Marinette Kagura Dupain-Cheng with blue locks, slanted bluer eyes, pointed ears, two magenta stripes on each cheek, and a magenta stripe on each eyelid, and a purple crescent moon on her forehead identical to the one her grandfather had. The baby girl was clearly a demon, a half-demon, but a demon nonetheless.
The moment Sesshōmaru held his grandchild, he was hers, “She is strong, and will only grow more powerful,” He told his exhausted offspring. “You did well daughter.”
“It takes two to tango,” Tom laughed.
Inuyasha just shook his head, “You’re not dead. Don’t push this.”
Over the next few years, Marinette spent most of her childhood split between her parents’ and her grandfather’s palace. Thanks to Shippo’s magic, it was only a portal away. She spent a lot of her summers there too. It was different when Marinette stayed with her Grandfather. She was different.
For starters, she was a princess and was expected to behave like one. She was a daiyōkai and was expected to act like; keep her emotions controlled and her word precise. When she was five-years-old, her grandfather presented her with two swords made from two of his fangs as a birthday present because, yeah, that was a thing demons did. One sword healed, the other destroyed. Though both swords were the same size; sword that destroyed had been too heavy for her to properly wield. She had to work for years to properly know how to use it. It was powerful and could slaughter a dozen foes with a swing. The sword that healed had seemed rather useless in comparison. It took her years to understand it was, by its very nature, the more powerful of the two.
When she wasn’t training, she was learning to rule. Demons lived a long life but things happened. It was best to be prepared.
It was at her Uncle’s insistence that Marinette, just recently turned six, be introduced to playmates of her own age. That was when Marinette learned something; everyone in the palace was employed by her grandfather. In addition, they were all lower demons subject to his rule and of any royal standing.
