Elvin, who transmigrated to become the only son of a mafia family, used his knowledge from novels and TV shows of his previous life to save the Cavendish family from impending collapse during a crisis, single-handedly rebuilding them.
Just as he was looking forward to a happy life, the appearance of a white-bearded old man changed everything.
It turns out this is actually the magical world of Harry Potter!
At the same time, the transmigration-essential cheat arrived, allowing him to draw cards by gaining prestige.
Elvin's appearance quickly began to change the wizarding world. Pure-blood families?

Hermione: "Becoming a vassal of the Cavendish family is the pride of my life."
Luna: "Esteemed Mr. Elvin, because of your appearance, the wizarding world seems to have regained its light!"
When Voldemort, after years of plotting, finally returned, he was stunned.
"Who can tell me why all my Death Eaters are now vassals of the Cavendish family??"
