[Harry Potter] Is This Hogwarts the Real Deal?

This Hogwarts is a real mixed bag. Is it really Hogwarts? HP!? Bungo Stray Dogs!? Magic Awakened!? What's the heroine's last name!? Grindelwald!??? So many characters!? [Ensemble cast. Mainly HP, with crossovers from Bungo Stray Dogs, Detective Conan, and Welcome to Demon School! Iruma-kun! Lots of absurd headcanons. OOC warning! Main pairings: Akutagawa/Atsushi, Soukoku, Drarry, and Grindelwald/Dumbledore. Read at your own risk!] The modern romance tag was added automatically. There isn't actually any romance (munch munch munch).
