All three saves have powerful characters, many UltraNovas, Colored Plates, etc. See the .gme save descriptions for more information. Check the notes using the DexDrive Explorer for info on each save. Sakurambo Warps you straight to the Programmers' Ending on Disc 2. Right before the final boss.
All classes are unlocked in each, and the characters are way too overpowered.
Interesting Scenes M. Save in the Debug Room. At final save point with Justin at max weapon and magic levels. Feena and Rapp are at about 50 magic and weapon. Liete at about 33 or so. At the end of the demo with all characters maxed out.
