Paidon, a manga made in part by an Osamu Tezuka AI with collaboration by Tezuka Productions, has received an official English translation courtesy of Frederik L. Schodt, who did the official translation of the Astro Boy manga.

Schodt's English translation gives the manga the name "Phaedo".

The manga can be read in it's entirety in the link above.

One of the policemen in a panel on page 12 looks like Tezuka.
And there's a character on page 13 with Astro's hair spikes.
