S Legend has it that it is a red and white koi from the Itai Fish Farm in Japan.
S Legend has it that it is 101 centimeters long and weighs 25kg. It was acquired at an auction for 203 million yen.
The reason why it is called the S legend is because the English names of Mr. Shirasaka and Itai Fish Farm both have the first letter S. Therefore, in order to commemorate this historic moment, Mr. Shirasaka named the fish "S-Legend". The Chinese name is S Legend, which can also be called Big S Legend.
