Fics like School diaries of a young girl

Peace is just another war. Just as she was about to enjoy her hard-earned promotion, Tanya von Degurechaff is snatched away by Being X and cast into an uncertain future. Stripped of her magic and her Empire, she finds herself adopted by a man named Loid Forger. Her new mission? Survive the prestigious Eden Academy. But with a foster father hiding his own world-class secrets and a sharp-eyed young detective from the East closing in, civilian life proves to be deadlier than the trenches of the Rhine. In a world of spies, shadows, and the Black Organization, can the Devil truly play the part of a perfect daughter?
