The Nagaya agency is run by Mrs. Hudson, has its own tendencies and matches up well with the shady environment. There, a highly ambitious and clean-freak detective and the deceptively charming sisters that make up the agency. And, if you think that there’s an old, wannabe police detective, ‘Anchan’ is there as he’s been excommunicated from the yakuza. Finally, there is their star act: a genius detective who loves Rakugo, Sherlock Holmes.

The curtain for this story rises on a night where a bizzare murder was just committed by Jack the Ripper.

Detectives all trying to suss out each other, Sherlock, Watson, and Moriarty, are all woven together with their camaraderie.
