[Genshin Impact Crossover] The Ultimate Character-Raising Plan

[Added this label at a friend's request. I'm done for.] [This story includes original headcanons and character changes. I don't mean to bash any characters. The changes are there to make the story more fun. If you don't read the author's notes, please read this instead. The author's sensitive, so please don't split hairs, okay?] Baili had always hated children. One day, while home alone playing with his newly acquired Shinkocchou Seihou figure, he was knocked unconscious by a badminton birdie that flew in through the window. When he woke up, he discovered he'd been bound to a System called "Brat-Raising." But apart from seven randomly drawn identity cards, the System had nothing at all. It couldn't even talk. Before Baili could complain about what a lousy System it was, with a golden finger that couldn't even be trusted, he transmigrated. Faced with a bawling infant, Bai Li, using one of his randomly drawn identity cards, stayed silent for a long while. Then, resigned, he put the Shinkocchou Seihou figure that had been bundled along with him by the System into the baby's hands and went to cook. One month later The baby, eyes brimming with tears: "Let's order takeout. Please don't go into the kitchen again." Baili: "..." I've spent quite a bit of money on Genshin Impact lately, so the game should get some use out of it. All the secret identities are characters from the game, and their personalities will influence the protagonist. But the protagonist is only wearing their identities, so there will definitely be some OOC. If you don't like that, please don't read. The protagonist has no love interest. There are side couples, but they won't appear in the main story. Readers who dislike those pairings can safely read this, but there will be bonus chapters about them at the end, clearly labeled. Just skip those if you don't want to read them. Tentative plans: Fire: Diluc, the Ara-gami Raising Project Water: Tartaglia, the Six Eyes Divine Child Raising Project Wind: Xiao, the Yuji Itadori Raising Project Earth: Zhongli, the Allen Walker Raising Project Thunder: Raiden Shogun, Should I Raise Muzan or Yoriichi? That's the question. Ice: Kamisato Ayaka, Cake Hot Pot, Heck Yeah, Sparrow Bro! Grass: I'll decide after Mihoyo releases a grass-element character (Come on, if you don't release one soon, I'm really going to cut you off). The order is undecided. Theme: Brats really are hard to raise.
