The Third Dark Lord Comes from Hogwarts

[No female lead. Hermione is a follower, similar to Vinda Rosier and Bellatrix.]

Argus initially thought he had been reborn. He planned to use his memories of his previous life to make a fortune and keep a few pets with sweet tem... temperaments.

Only when he met a white-haired old man with mismatched eyes one day did he realize that he had actually transmigrated into the world of Harry Potter-and was the last surviving child of the Grindelwald family!

After lying low for years and using his system to max out his talents, Argus finally steps into the limelight!

Animagus? Isn't that something anyone with hands can do?

Occlumency? Maxed out without breaking a sweat!

Dumbledore: "I thought Voldemort's talent was unrivaled. I never imagined someone could be even more formidable!"

Snape: "In front of Argus, no one dares call themselves a Potions genius!"

Voldemort: "You call me the Dark Lord? Argus is ten thousand times darker than I am!"

Having become Gellert Grindelwald's adopted son, Argus inherits his father's will and is about to lead the Acolytes' return.

But first, he must deliver a speech at Nurmengard that will shake the world...
