Set in the near future in the Great Era of Detectives…
Wikipedia’s already won me over with the first line of this plot summary, which reads like it was written by T-Rex, but it gets even better:
… chosen people are born with supernatural abilities known as Toys (トイズ Toizu). Those who use these Toys for evil are responsible for a wave of crimes and necessitate employing Toy-using detectives to help solve them.
In the anime series, the four girls, Sherlock, Nero, Hercule and Cordelia, lose the ability to use their Toys during an encounter with the phantom thieves. Taken away from their rich lifestyle and thrown into an attic, the girls must try and regain use of their Toys or else face expulsion from Holmes Detective Academy.
It also suggests an excellent opportunity for trolling: make a bunch of posts outraged about CBS’s Elementary, how it goes against canon, gets the gender of characters wrong, etc, then when you’ve got a bunch of obsessive fans of the BBC Sherlock to follow you, start posting about how Sherlock is even worse because it ignores all the proper Tantei Opera Milky Holmes canon, makes the character of Sherlock “Sheryl” Shellingford into a man, and so on.
