Employed at a university hospital on the west side, John H. Watson is looking for someone who can assist him with an odd case. His search leads him to the Pipe Cat, an underground bar that serves as a meetup venue and job board for some of the best detectives in Shinjuku, the most prominent among them being Sherlock Holmes. Upon finding the bar and meeting the peculiar investigators, John learns that they are pursuing a case involving Jack the Ripper, an infamous serial killer.
