Otogi Zoshi (お伽草子, Otogizōshi) is a Japanese animated television series produced by Production I.G.
A manga adaptation was published in Comic Blade in 2005.
The story is divided in two story arcs. The "Heian Chapter" takes place in Kyoto during the Heian period and follows Minamoto no Hikaru, the younger sister of Minamoto no Raikō, on a quest to save Japan. The "Tokyo Chapter" follows the reincarnations of Hikaru and her comrades as the ancient evils of days past manifest themselves in present-day Tokyo.
The "Heian Chapter" is set in the middle of the Heian period, where the people of the capital of Kyoto are in deep agony, focusing their last hopes on the retrieval of the five magatama that represent the five elements (Metal, Wood, Water, Fire and Earth). Legend has it that when the magatama are laid together, their circle of Affinity will save the capital from suffering and whoever places the last stone is to become the emperor.
Three of the Magatamas are scattered throughout Japan. The Emperor, relying on the prophecies of Abe no Seimei, delegates the task of recovering the three lost Magatamas to Minamoto no Raikō of the Minamoto clan. However, Raikō is struck by an epidemic and barely able to move. Instead his younger sister, Hikaru, secretly takes his place.
