Hogwarts: The Alchemist’s Wand

[The heroine is Hermione (in appearance only). You can skip the setup in the first few chapters.]

A magical alchemy wand, combined with the twelve zodiac animals, travels across timelines.

“What, Dark Magic, white magic? I don't like either.”

“Then what do you like? Hmph.”

“You silly thing. I like you!”

Your gentle smile is like a plum preserved in dark plum sauce.
