Ambiguous name, making reference to two different but very similar units: the MSN-06S Sinanju Stein, the prototype successor unit to the Nu Gundam developed by Anaheim Electronics, of which one was stolen and extensively modified into Full Frontal's personal Sinanju, and the MSN-06S-2 Sinanju Stein, a slightly cosmetically altered version of the prototype piloted by Zoltan Akkanen.
