A giant robot show that skips the fights entirely. Shoutarou just lives with a sentient tank in his basement, and the comedy comes from him pretending everything is normal while his robot casually destroys the neighborhood doing chores. Pop-art style means it looks like a comic book that learned to move, bright and stupid and completely uninterested in saving the world, just in whether a five-minute episode can make you laugh at the absurdity of owning a giant robot and treating it like a household pet.

Shoutarou Kaneda is the protagonist of these short episodes, each about five minutes long. Earlier Tetsujin 28 titles centered on battle scenes, but this one turns to Shoutarou's everyday life instead. The title robot and its nemesis Black Ox both appear, drawn in a pop-art style along with the rest of the show's visuals. The result is a mecha series with a slice-of-life focus, running for 151 episodes.
