In the middle of a possible Stray hunt, Rias Gremory accidentally ended up with three marks on her hand due to activating an unknown spell. After researching them, she discovered their use of calling forth a possible familiar. But what came from the summoning was a familiar that not even a Devil could have ever imagined.

What will this child learn at Hogwarts about magic, about himself, and about love? Harry potter belongs to J.K. Rowling and Y/N belongs to the reader.
