Kanahei is an illustrator active in Japan, and the word also refers to the characters she has created. She has created various characters, but especially famous are the pink rabbit 'Usagi' and 'Pisuke', who is always with Usagi.

Pisuke is a white bird often with Usagi. He has a very serious personality and basically does not get angry even if Usagi messes with him. But sometimes he gets angry. Sometimes he is too serious and causes incredible trouble that even Usagi can't predict.
