And lest you think this is one of those strange one-off fad restaurants that cater to a niche clientele, several of these have been humming along for years, all staffed by every dude from high school who wouldn't shut up about Sailor Moon. These guys serve cake, flirt, and help edit patrons' English-language diaries for clarity and significantly more instances of the phrase "dope-ass white boys." Women are treated like princesses, which includes the option of wearing a tiara or receiving a little bell to summon their butler.
The question that immediately springs to mind is "Why would anybody want this?" Or if you're currently wearing three pieces of Overwatch merchandise, "Where do I apply?" These customers don't want hyper-masculine men; they want hyper-polite men who will let them unwind from their stress. The interest comes from Japanese women looking for a way to reject Japanese men, or at least the ones they see as "disrespectful, narrow-minded, and unable to care for themselves." Boy are they in for a rude awakening about American nerd culture.
