I hate people negarepping for disagreeing. I'd be soooooo far into the red had that been the norm XD
Actually, both Roxas and Namine are exceptions, but the fact is that that's what lets them age. Also, their Hearts not being covered in Darkness and thus their Senses of Self can be "updated" (Roxas would get new Memories from Sora as he grows older even on a physical-Memory level, and thus would grow older too) so that can explain it as well.
And I negad him. Really. EVERYONE tells him he's wrong and he comes after me.
So back to ignoring him~
