You will note in the most recent Birth By Sleep scan, Master Erauqs's keyblade has a keychain. People have been speculating for a few years now on the significance of keyblades with or without keychains.
It seems that only true Keyblade Masters have Keyblades with keychains.
Aqua, Terra, and Ven are all apprentices to the Keyblade Master Erauqs so they might not be considered true Keyblade Masters yet.
