CS1 was the starting chapter so even if the characters were not very good, it's still acceptable. CS2 is where thing get hot but none of the main cast has anything new to add to their personality. In fact, I have the feeling that they became even flatter. Everyone is the same, some even managed to become dumber. The story is lame, there's no twist, no interesting confrontation until the very end of the game. I have to say the bad guys in CS2 is probably the worst bad guys in Trait series and I have played the Sky trilogy and the first Kiseki game.
