Plot
Haruka and Aoi are a pair of friends who become the magical Twin Angels in order to fight off evil as the Red and Blue Angels. Their story revolves heavily around tracking down and protecting Seven Amulets; magical pieces of jewelry capable of generating immense power when assembled from a mysterious man known only as Black Trader and his subordinates. They are eventually joined by Kurumi the White Angel.
In the new season, Kurumi (in the form of a hedgehog) seeks the help of Meguri Amatsuki and Sumire Kisaragi as the Rose and Sapphire Twin Angels-in-training, when Haruka and Aoi go missing. This story is about hunting down a mysterious woman known as Mary and her pawns that aim to revive a demon ruler by collecting medals contained with innocent energy sources.
