The Legend of Dororo and Hyakkimaru manga volume 3 features an original story by Osamu Tezuka, with adaptation and art by Satoshi Shiki.

The Banmon is a grim barrier between lands, a line that no man can cross alive. Its guardian: Tahomaru, a mysterious warrior with the same prosthetics as Hyakkimaru. Both men lost pieces of themselves to demons, and both men stood tall again thanks to the inventions of doctor Jukai. In another world, they might have met in friendship. But with Hyakkimaru’s companion Dororo missing, a fated and bloody conflict looms.
