Sora...... is the man protagonist in the series. Roxas is the nobody (look that up if needed) of Sora. Ventus is not related to the two, but his heart remains in Sora after his fight with Vanitas . Ventus is the reason Sora holds a key-blade . Back when námine put sora to sleep , it must have possibly been a miscalculation , for rather taking the appearance of Sora , it took Ventus , since he is in Sora's heart.
