Jido is a middle-aged man and Ted's bookkeeper. He assists Ted in searching for Cherish by traveling together on Jido's motorcycle. Despite their extensive travels around the world, they have not yet found her, residing temporarily in various towns. During their time in Japan, it becomes evident that Jido and Ted are constantly on the move, battling Mamodo, which makes it difficult for them to trust other Mamodo. However, upon meeting Zatch and Kiyo, it is revealed that they selectively engage in fights when necessary and eventually form friendships.
In the manga, after Ted's book is burned, Jido continues to support Zatch by restraining Lupa and compelling him to aid Zatch. It remains unclear whether he continues to travel the world afterwards, but there is a scene showing Ted sending Jido a letter along with a postcard, updating him on the events occurring in the Mamodo world.
