She had a dream: the world was brimming with light. Family. School. Friends. Trains. Buses. Movies. Books. In that world of light, she grew into adulthood… and at the very end, in a white room, she fell into darkness. She awoke from the dream to find that she had become a demon. In the demon world, she lived a carefree life until she encountered a powerful being.
After such a long time spent living as a demon, before she knew it, spreading in her heart was a yearning for that world of light. She plunged herself into a summoning magic circle that had appeared. Then… when she opened her eyes once again, she had become a human baby.
She was in the Holy Kingdom. She felt fearful: while she was indeed a demon, she only had the strength of a baby. Her being a demon, if discovered, would be terrible. Was she a human or a demon? Would she be able to survive from here on out?

The manga takes place in a world where everyday life has suddenly crumbled away. In front of a young girl who is only waiting for death in this ruined world, a lone young man descends from an empty sky.

Daigo Kagemitsu, who works for a Samurai general in Japan's Warring States period, promises to offer 48 body parts of his unborn baby to 48 devils in exchange for complete domination of the country. When the baby boy is born, Daigo has him thrown into a river, hoping the boy will die. A kind sage, however, finds him and adopts him. The sage fits out his poor son with prosthetics.

Time goes by and the baby grows into a boy who calls himself Hyakkimaru. Everytime Hyakkimaru eliminates a devil, he retrieves one of his missing body parts. Hyakkimaru meets a boy thief named Dororo and together they travel the countryside in search of the devils who possess Hyakkimaru's parts. Throughout their travels, they face monsters and ghosts.
