Reading through my LiveJournal friend's page I came across a link to a story about Japanese love hotels.
Adonis specializes in S&M rooms and cute cartoon characters/ Maybe it was inevitable that the two would be combined to make the "HELLO KITTY SM ROOM". There's even a Kitty-chan plush doll wearing a ball gag, blind fold, and barbed wire garter belts that will give you nightmares for years. Adonis also has a room with glow in the dark jelly fish, a prison cell, a high school classroom and some really scary S&M rooms. [Lovehotels]
Personally the idea of the Hello Kitty S&M room just makes me a bit nervous and a little disturbed. Now, a Badtz Maru room, that would be more fitting.
