Okawari-Boy Starzan S (オカワリボーイ スターザンS, Okawari Bōi Sutāzan Esu), or simply Starzan S, is an anime created by Tatsunoko Production[2] from an idea by veteran studio director Hiroshi Sasagawa.

[3][page needed] Canceled at only 34 episodes due to low ratings, the series was one of the Tatsunoko studio's more obscure works until the series was released on video in Japan on Blu-ray by TC Entertainment in 2017.

[4] "Okawari" is a Japanese expression used when the user is requesting a second helping of food or drink.

The Senobi tribe love nature and want to live in peace without being harassed by the others.

On the other hand, the formerly high-tech Robot tribe have become militant as they want to expand their sphere of influence from the desert to the wooded region.
