Watch Mecha Gishi Resta no Daibouken Episode 1

Episode 1: Resta is a talented young mechanic who specializes in developing and repairing machines. Her ordinary life changes when a serious incident occurs in her town: a large number of robots suddenly go out of control after being hijacked by an unknown person through radio waves. The machines are no longer functioning as ordinary mechanical devices and have instead been transformed into aggressive HENTAI robots that specifically target the women of the town. As the town's security engineer, Resta decides to personally deal with the crisis rather than leave the situation to others. However, the rogue machines prove to be far more dangerous than she anticipated. Their mechanical bodies have been equipped with unusual weapons, including tentacle-like mechanisms capable of restraining their targets and subjecting them to intense stimulation. Resta's technical knowledge and determination initially allow her to confront the machines, but the increasingly aggressive attacks make the situation difficult to control. The story follows her struggle against these corrupted machines as she attempts to overcome the threat and restore order to her town. The conflict places the skilled mechanic in a situation where mechanical technology has become an unexpected source of danger. Alongside its science-fiction-inspired mechanical premise, the OVA incorporates fantasy and magical-girl elements, creating a distinctive setting for Resta's confrontation. The narrative remains focused on Resta and the rogue robots rather than developing a large supporting cast, allowing the central mechanical crisis to drive the story.
