This is a set of the TV broadcast version (cell version) of Kinnikuman Nisei and the sequel, Ultimate Muscle (rental version), which gained popularity overseas. The DVD cell version (complete set) of the TV broadcast is as rare as the Ultimate Muscle cell version, so it's expensive, but I think it's worth it. Regarding the condition of the items: The cell version is relatively good considering its age, but there are scratches and minor imperfections on the case and discs. The rental version was more deteriorated than the cell version from the time I purchased it. All volumes have been tested and are working. I am also selling the cell and rental versions separately, but it's more economical to purchase this set. This listing will be removed if either one sells. Immediate purchase is welcome. Thank you for viewing.
