What do the sheep dolls represent in Mayo Chiki? Are these sheep dolls mascots, or do they represent something in the series? From the look of it, the blood (?) drooling from their mouths is like Sakamachi Kinjirou's nose bleed.
It's a mascot for the series. Subaru is a butler, and in Japanese, "butler" (shitsuji) and "sheep" (hitsuji) sound the same, making it a play on words. The reason it is bleeding is itself a pun because a sheep bleats.
