Shōshō Akatsuka serves as the younger brother of Taisho, debuting in the first anime adaptation and appearing in every subsequent animated version. He remains perpetually depicted as a toddler capable of speech but unable to walk independently, relying on the family cat Dora for transportation by riding on its back. His name, translating to "Major General," positions him as the junior counterpart to his brother, who holds the title "The General." This name is likely a nickname rather than a formal given name, as official media never discloses his full personal name despite confirming Taisho's as Daisaku Akatsuka in the 1988 anime. Shōshō functions as Taisho’s sidekick when other children are absent, participating in his brother’s schemes and misadventures while constrained by his age and dependence on Dora for mobility. Their recurring dynamic emphasizes a familial bond, with Shōshō viewing Taisho as an older sibling figure. The 1969 anime adaptation features their father, but no other family members appear across any media beyond this core trio. The character features in all three television anime adaptations (1969, 1988, 1998) and the 1989 festival film *Umi da! Obake da!! Natsu Matsuri*, joining Akko and others during a beach holiday. His role shows no evolution in age, abilities, or relationships throughout these appearances. Shōshō exists solely as an anime-original character, absent from Fujio Akatsuka’s original manga runs and the web manga *Himitsu no Akko-chan μ*.
