Ojarumaru or Prince Mackaroo is an anime created by Rin Inumaru back in 1998. The story focuses on the adventures of a 5-year-old Heian-era prince with a weakness for creme caramel. As time goes on, Ojarumaru makes many new friends, while dodging the comedic efforts of the three demons, as they try to recover the stick. You can download the three demon papercrafts named Akane, Kisuke, and Aobee as well as other robot and characters from different anime here.
On a sad note, creator Rin Inumaru committed suicide by jumping off the 14th floor of her apartment on Sept. 10, 2006.
