My HP Was Transformed by the Magic World and I Became a Demon King.

(Being the favorite of the group + focusing on career + ambition + system + not being a saint + leaning towards dark literature) The author has been busy recently, but this book will be finished anyway, don't worry, hehe And who will be with me in the ending? I will basically write a plot for each character, so don't worry (❁´ω`❁) But the main plot should be with Tom, after all, he is fighting and grabbing. Venia was reincarnated as the only daughter of the Selwyn family and traveled to the magical world of Harry Potter. Should he strangle the future Dark Lord in the cradle, or kill the savior? Of course, Venia chose neither of them, and directly decided to train the Dark Lord into a love brain. It is better to train a dog than to kill people, and it is not certain who is more evil between her and the Dark Lord. Who said that the villain can't be the protagonist, and how did she step by step trample the entire magical world under her feet? When the overall popularity is towards the end, the most popular ones will have a split ending. Lightning Protection: The timeline is confusing, serving the plot, and also a bit OOC.
