A 10-year-old builds a time machine and his robot sidekick is chaos incarnate — what could go wrong?
25 minSeason 1 • Episode 331
LatestThe main character is a scientific genius boy named Kiteretsu, who has built a companion robot named Korosuke. He frequently travels in time with his friends and Korosuke in the time machine he built. Miyoko is a girl in his neighborhood who is basically his girlfriend. Tongari is his rival, who happen to share some similar traits of Honekawa Suneo. Buta Gorilla is a typical neighborhood bully, who also share similar traits of Gian except that he often antagonizes Korosuke (though they are in grade school).
Acting
Mami Koyama's Korosuke voice is pure unhinged robot energy.
Writing
Fujiko F. Fujio's gentle moral lessons hit harder than expected.
Practical Effects
The gadgets look ridiculous and that's exactly the point.
Trivia, insights & behind the scenes
Created by Fujiko F. Fujio of Doraemon fame, this was his lesser-known 'what if the genius was the protagonist instead of the robot?' experiment that ran parallel to his mega-hit.
The 331-episode run makes it one of the longest single-season anime ever — a relic of the era when shows could just... keep going without arc structures or streaming binge logic.
