Hogwarts's Sword-wielding Death

(No heroine + tearing umbrella in the rain + original god card + funny and relaxed)

The protagonist begins by fusing the soul of the Grim Reaper and directly robs Dumbledore's Philosopher's Stone! Becoming the Demon King of Hogwarts.

He joined the Nazarene Church, became a professor, trained Draco and Harry, and became Theodore's father.

Create an army of undead and treat Voldemort's remaining soul as a crunchy snack gift pack.

Occasionally, I would get furious with Dumbledore and Grindelwald, and this comfortable life was simply wonderful.
