This will be a unique experience for everyone.

Hiroshi, an employee from tech firm ZIC has just developed a device that allows his body to ignore the laws of physics, dubbed the MOL-Unit, this allows him to play Superman for a short time, 666 seconds to be exact with the added condition of not being able to wear clothes for the transformation. When his sister finds out what he's been doing she adds her own feminine touch to the program making a female version of the hero form. Unable to use a female body to fight, Hiroshi lends superhero duties to Mirai so she can fight the androids of mad scientist Dr Machinegal who keeps stealing 20th Century artifacts. Adding to Mirai's dilemma, her crush is off to space to discover the universe beyond.
In six episodes, Moldiver packs more into it's anime than shows that last longer than 50, it's an intriguing plot that celebrates 20th century culture with a unique and scientific version of making Superman. It's a quirky OVA with a retro style sci-fi feel backed up by a likeable cast of characters. It can be corny on occasion and little brother character Nozomu's motives are questionable when such high stakes are present but is nonetheless a solid OVA.
Dub is very basic with Dr Machinegal stealing the show and Mirai sounding more like a Nickelodeon protagonist.
My biggest takeaway from the anime is how much care it takes in presenting 20th Century artifacts like the Six Wheeled Formula 1 car, the Battleship Yamato and the Apollo 11. Keep in mind it's set only 25 years from now so the events are mostly plausible. These types of Sci-fi stories just work better.
Final Verdict: A solid Sci-fi story with a slice of cheese to go with it's already well packed six episode run.
