Hogwarts: Teaching Harry the Killing Curse from the Start

From the start, I burned the Sorting Hat, then taught Harry Avada Kedavra!

I transmigrated into the body of an elderly Dumbledore and was bound to the Dark Lord Development System. If I didn't raise Harry into the next Dark Lord, I'd die!

So, at the opening ceremony, a flash of green light blasted through the ceiling. I burned the Sorting Hat, put an arm around The Chosen One, and announced:

"From today on, Hogwarts teaches nothing but the Unforgivable Curses! Who's with me? Who's against me?"

Then I sent Voldemort a threatening letter: "Lay another finger on my future Dark Lord, and I'll personally teach you 108 ways to cast Avada Kedavra!"

The Ministry of Magic came to investigate? I hung Fudge from a chandelier in the Great Hall and livestreamed an Imperius Curse lesson: "Watch closely. This is how you control the Ministry of Magic!"

I thought this was just a survival mission, until the System announced:

Ultimate Mission: Be defeated by Harry, now a god, and bring about the succession from the old Dark Lord to the new. Mission reward: resurrect Ariana.

Looking at Harry, whose gaze grew colder by the day, I wore a bitter smile for the first time.
