Also known as: アストロボーイ・鉄腕アトム
Professor Ochanomizu resurrects Atom, a groundbreaking android created by the vanished Professor Tenma as a replacement for his lost son Tobio. Though Atom possesses superhuman strength, intelligence, and an uncommon heart, he discovers a world where robots are feared as threats rather than embraced as companions. Determined to bridge this divide, Atom fights to prove that humans and machines can coexist peacefully.
