Born on December 7 in Ibaraki prefecture, Japan. Although he has a long career in the manga industry, he has been active as Shu Sakuratani for the past seven years. When he was a child he had a chicken which he loved and cared for. Then one day his grandmother turned it into delicious fried chicken. Later he was told about this and has regretted eating it ever since. Perhaps the creation of Rooster Fighter is related to this painful memory. Maybe.
