Hogwarts: What's Wrong with a Necromancer Becoming a Professor?

He transmigrates to the world of Harry Potter, becomes Professor McGonagall's adopted son, and awakens the Undead Archmage System.

As long as he collects negative emotions, he can earn treasure chests.

He enrolls at eleven and wages bloody battles against the Pure-blood families.

At seventeen, he graduates and hangs around Knockturn Alley, where he's dubbed the "Throne of Bones"!

At eighteen, after Carl receives an offer of employment from Hogwarts, the entire Wizarding World is in for trouble.

Snape: "Dumbledore, you really ought to see this. Hogwarts has become a gathering place for Dark wizards."

Sprout: "Ever since these children met Carl, they've spent all their time in my Herbology classes studying poison-making."

Dumbledore: "The Three Unforgivable Curses? You call that beginner-level magic?"

Carl: "What could I possibly have done wrong? I only taught them a few Dark Magic tricks for self-defense."

"What? A complaint? What's wrong with an undead wizard like me teaching at Hogwarts?"

"Don't worry, Headmaster. I'll wipe out the complainant's whole family tomorrow. Oh, no, I mean, I'll take care of it!"
