This "Class Up Armor (Rozen Paladin)" armor set from Bandai can be used with their "30MF (30 Minutes Fantasy)" series of plastic models! This set of armor and weapons can be "classed up" to a higher-tier job by doing armor replacement -- you can "class up" to Rozen Paladin by combining this armor with the Rozen Knight (sold separately). 

Paladin is a job that has sword skills at a higher level than a knight, and has increased physical defense power. The face design and coloring are different from the Liber Republic's Paladin, which is sold separately.
