The Sunlit Time Elevator (HP, Crossover)

I transmigrated for no apparent reason, then arrived a thousand years in the past. Was it the era of the Four Greats, or something else? I came up with this story on a whim one day, but never posted it. If you’re bored, it should at least help pass the time. The story is set mostly in a rather obscure era. Back when that shady merchant hadn’t yet become captain of the Twelfth Division, there was a lieutenant named Sarugaki Hiyori. Next door to the Twelfth Division was her good friend, Shiba Cia, a Third Seat in the Thirteenth Division who was known for her slight poker face. Back before the Chosen One was born, when Hogwarts had just been founded, there was a headmistress named Helga Hufflepuff. Beside Hufflepuff House was another house called Slytherin, where her dearest friend Sylvia lived. Back before Ciel made his contract and Sebastian became a demonic butler, there was a Shinigami named Sylvia. She said, “As long as it’s your wish, Sebastian and I will make it come true.” When everything returned to the beginning, she gained a body. Voldemort and Dumbledore: her wait would become a magnificent battle. But one day, she wanted to ask: where would she go from there?
