Hey I'm Sutaa!! (Star in japanese) And these are my theories! Roxas = Ven with memory erased. Aqua=Xion trying to help Ven and Terra remember their past lives. Terra=Xehanort in the future trying to get revenge for what master Xehanort did to Vens heart. This is me: I'm Soras sister. Born in destiny islands raised in Crystal Rock. Born 10 mins before sora in love with riku if you post comments i'll tell you more!!!!!
