Tragedy of an Ultra-fine Room

Synopsis

At an almost-completed building, the owner Toranomon shows three visitors the construction site. When Black Jack appears demanding 50 million yen in unpaid surgery fees, Toranomon refuses to pay. Pinoko joins them as they all enter the security area. To demonstrate the anti-theft and disaster prevention systems, Toranomon activates a protective wall. But when he tries to deactivate it, the button fails—Black Jack, Pinoko, and the others are trapped behind the protective wall, cut off from the outside world.
