[Crossover] Red and Black

A black umbrella, a red umbrella. A clash between the British government and the Ministry of Magic. Grindelwald has been defeated by the greatest white wizard of the century, and his remaining followers are still being hunted down. Margaret Black, a young red-haired witch, is already deputy director of the Department of Magical Accidents and Catastrophes. During the war, she was a battle-hardened Auror. After the war, the Ministry of Magic lies in ruins and desperately needs rebuilding. The young heroes have stepped in for their aging predecessors, becoming the Ministry's backbone. Postwar London is shrouded in mist, in both the magical and Muggle worlds. Grindelwald's followers have fled into the Muggle world, hoping to recuperate and launch another attack. The Ministry of Magic has no choice but to begin cooperating with the Muggle government, and Margaret, who is of mixed heritage, takes charge of the effort. Mycroft Holmes, the brains behind the British government, is forced for the first time to accept the existence of the "magical world," a concept that defies science... But how could he allow anything beyond his control to exist in Britain? This is a partnership between red and black, and a battle between red and black. Theme: Peace
