Original name Kyuso base on Japanese folklore
After 1,000 years passed he was able to transform himself similar to human form but still have the red skin color with his ear pop out and sensitive sense of danger. After turning into human size he is now able to protect his fellow and family from any danger. He always has a bamboo flute with him to guide the way for other rats to not lose track wherever he goes. If you heard a flute come from the wood you may assume that the rat fellows are moving somewhere.
