A story of a strange friendship between Yamataro, a koala bear who lost his parent in an accident and a mountain hunt that was kept by humans, and a steam locomotive named Shiroku.

"Essay on Idleness of Animals" is a very short story that combines narrative with a sarcastic touch delivered through animals. Beginning with the monkey in the first episode, a different animal is featured in each story. Tezuka Osamu used various writing and drawing techniques to depict the unique characteristics of each animal. At the time, this work was noteworthy for its experimental cartoon form. Of particular interest are the second episode "Raccoon Dog" and the eleventh episode "Horse" because Tezuka Osamu used his hometown Takarazuka as a backdrop for the narrative of the Manga in these two episodes.

This tells the story of two brothers, one a cop and the other an aspiring songwriter, who find themselves mixed up in the student protests of the late 1960's in Japan that are being led by a Christ-like folk singer.

This One Shot was published in "Weekly Shonen King" as the second part of "Kami no Toride" in January 1975. The war is finally over, but this time a desperate food crisis has come, and Tetsuro Osamu struggle to survive has begun again. Osamu steals potatoes from the fields, draws portraits for the occupation soldiers, and receives sweets in exchange for pocket money. For those who have to make it through the day, even the dead bodies of the dead are out of sight. Although the story is light-hearted and filled with gags, it has a sense of reality that could only have been depicted by someone who actually lived during this period. Initially, Tezuka planned to make this a trilogy of "Kami no Toride", but the third part was never drawn.

Story created for Osamu Tezuka's 90th birthday. Inspired by his 1979 work, "Lunn flies into the Wind"/"Run ha Kaze no Naka".
