A show called “Hello Kitty and Friends Supercute Adventures” might be expected to feature the world-famous cat more prominently than one of her lesser-known companions. In fact in its most-watched episode, “Kuromi’s Bad Day”, Hello Kitty plays a supporting role, cheering up grumpy Kuromi, a rabbit dressed in hot pink, with milk and a doughnut. Nor is this an isolated relegation. In an annual poll of fans’ favourite characters, Hello Kitty has won only once in the past decade.
