A spin-off of the popular Crayon Shin-chan franchise, the series focuses on the adventures of Shiro, a seemingly-normal family dog who, when the Earth is threatened, secretly transforms into a canine superhero to protect the planet from nefarious villains.
With his human family often involved in various adventures, Shiro is frequently left to his own devices, and it is during these times when he is alone that the secret life of this extraordinary dog is revealed.
His mission is to find and secure the "Bobobobobone," a legendary dog bone that, it is said, grants its owner the power to rule the world.
But Shiro isn't alone in this quest: the scheming canine scientist Dekapoo is also after the bone and hopes to use its powers to make himself World President.
Before long, the search attracts other doggy attention, including from Can Can, a stylish lady hound who's just as eager to make the "Bobobobobone" hers.
[2] Production of Super Shiro arose out of director Masaaki Yuasa's longstanding affiliation with the Crayon Shin-chan series.
[6] With regard to the slapstick format, Shimoyama stated that the series afforded him, Yuasa, and the animators an unusual degree of freedom.
[6] For the role of Aura, Setsuji Satō was also envisioned from the beginning, as he had previously played a mysterious character in Yuasa's anime series The Tatami Galaxy (2010).
[6] Anri Katsu, who played Dekapoo, was identified by Shimoyama as a master of ad-libbing moments which enhanced the visual slapstick; as a result, many of his line additions and alterations were incorporated into the episodes.
Shimoyama ultimately decided to keep Dekapoo's scripted lines to a minimum, allowing Katsu to fill in the rest based on the suggestion of the storyboards and animated visuals.
Katsu helped inspire the other actors with interpreting the visuals (which were often not finished at the time of dialogue recording) to have a better sense of how to play each scene.
