This is 1982 asking a question nobody else was asking: what if the bad guys had a leasing company? The show treats corporate villainy as seriously as it treats robot battles, which means you're watching a comedy about market competition where the stakes are actual destruction. Ippatsman's team runs Time Lease like they invented customer service, Skull Lease runs chaos like a legitimate business strategy, and somehow the show makes you care about both sides long enough to forget which one you're supposed to root for. It never settles the question. It just keeps the machines running and the rivalries personal. That's the whole thing.
In the Osteandel City of the 1990s, Time Lease runs a rental business that will lend out nearly anything, powerful robots included. For ten years straight it has topped the international list of billionaires. But a rival outfit in the same city, Skull Lease, has other plans. A notorious villain trio serves there as top executives, and their stated aim is to ruin Time Lease's reputation and take its place as the leading company. What they really want is a foothold for conquering the world. When the trio attacks one of Time Lease's transport robots, Ippatsuman steps in to fight for justice. The sixth entry in the Time Bokan series, it is a science fiction TV show that ran for 58 episodes.
