The prestigious Manaria Academy serves as a neutral ground where members of all three great factions can learn the magical arts. It’s here that Anne, the human princess of Manaria, and Grea, a half-dragon princess, first meet and strike up an unlikely friendship.
An often comedic slice of life series with strong hints of romance and noticeable ecchi elements. While taking place in the same universe, it has no direct connection to either of the previous Shingeki no Bahamut series.
