Dororo

is a Japanese manga series written and illustrated by the manga artist Osamu Tezuka. Tezuka's childhood memory of his friends pronouncing as dororo inspired the title of the series. Dororo was first serialized in Shogakukan's Weekly Shōnen Sunday between August 1967 and July 1968, before being cancelled. The manga was then concluded in Akita Shoten's Bōken'ō magazine in 1969.
