Loose adaptation of Osamu Tezuka's Dororo. After the war, robots were creatures mass-produced as labor that, now, overflowed the city. Some were on the street and some in the back society, creating bonds with the citizens. One night, a girl who is neither human nor robot appears in front of a Yakuza creature that had seized the orphan Doro. The girl, wearing beast's fur, attacks the creature reveling extremely strong weapons attached on her limbs. Who is she? What is she fighting for?
