The Elder Lord of Hogwarts

An ordinary college student unexpectedly transmigrates into Hogwarts as an ordinary first-year. He thought he would just study and chase girls step by step.

However.

Why is my talent so high?

First year: A fearless rookie stomps on the arrogant Dark Lord, shocking the entire wizarding world.

Second year: Bursting onto the scene, he trounces the legendary Merlin, becoming a god in magical history.

In this magical world, others' childhoods are about riding brooms, learning spells, and worrying about final exams.

But my childhood? It's about teaching Voldemort how to behave!

And making the entire wizarding world address me as the Grand Archmage... What? Dark God? That's a derogatory nickname used by the remnants of the Death Eaters!

Wait, I'll go extract their souls and use them as lanterns.
