[Harry Potter] Raising a Dark Lord

Part One: Falling from heaven into hell naturally means gaining some things and losing others. What was gained was freedom. What was lost... seems like a lot. At the very least, Mephistopheles never had to go hungry in heaven. "Tom Marvolo Riddle, from this moment on, you are my emergency rations." Unfortunately, the prey is still too small. There's nothing for it: before I eat him, I'd better raise him until he's more delicious! But food... can fight back. Part Two: The child blessed by the gods turns out to be the reincarnation of a demon. The eyes of all kinds of humans and nonhumans fall on the innocent-looking baby: fear, joy, fanaticism, covetousness, hatred... Which is the real one: the rising star of the magical world, Tom Riddle, or Lord Voldemort, master of the dark world? On September 1, 1971, Hogwarts faced its greatest crisis since its founding: werewolves, vampires... and a walking calamity. P.S. 1. No transmigration! 2. The protagonist is a bona fide "demon"! So don't expect him to make V-sama mend his ways... We should already be thanking Merlin and Vivian if things don't get worse. 3. Mephistopheles is the unfortunate demon in Faust, and should be another name for Lucifer. 4. The cover art is from a collection by You Hiyori. Please support my other stories, too! O(∩_∩)O~
