Reborn as Sesshomaru's Daughter? No, I Don't Believe It

Shan Naili transmigrated. And not in a particularly clever way. She thought she might have transmigrated into a world of demons... And she even knew the demon in question... Sesshomaru! Then she thought about her own name: Shan Naili (Sha Naili)! A dreadful thought appeared in her mind: Oh no, was she going to become Sesshomaru's daughter? Who had a child with Sesshomaru?! This was insane! Sesshomaru thought the clan's cub might have something wrong with her head. She was always staring at him for no apparent reason. As a cold-hearted great demon intent on conquering the world, looking after a cub was not something Sesshomaru was good at. Naturally, he didn't think he ought to be good at it, either. But... This was the only cub the Moon Dogs had seen in nearly five hundred years. She had been poisoned at birth and didn't wake up until she was nearly an adult. The dog clan was full of dangers, so he had no choice but to keep her by his side. Still, he couldn't help thinking she wasn't quite right in the head. Because... "Father!" When he heard the cub cheerfully call him Father, Sesshomaru, who was 410 years old and still a boy, not yet an adult, completely cracked. Shan Naili thought Sesshomaru might not be quite right in the head. Because after she called him Father, he didn't seem happy, and he wouldn't even give her food! 1. The story will begin when the advance collection reaches 1,000. Once started, it will be completed. 2. Sesshomaru BG. No Sesshomaru/Rin pairing. Please keep to your own lane. 3. I haven't figured out the rest yet. I'll add more later. Theme: Become a better version of yourself
