So... Wow. I figured Noel was just more reserved than Anna being twins and all. I thought Charlotte was just acting like that because of her backstory and the way she regards everyone. When i first played Reborn I chosed Decibel and i figured xe had to be a little unpredictable because of the style of clothing. So the other protags have no distinct personalities other than Decibel? By the way you describe Deci, it seems almost if xe has mild ADHD.
