Wayward Wind

Unreleased Ven's Keyblade belongs to Ventus, one of the central protagonists in the upcoming prequel: Kingdom Hearts Birth by Sleep.

It is a notably peculiar Keyblade, with a handle that is to one side, rather than in the centre. The teeth are more "mechanical", resembling the teeth of Serendipitous Pair, whereas the handle resembles that of the Kingdom Key, therefore creating yet more connections between Ventus, Sora, and Roxas. Ven usually wields his Keyblade left-handed, but he can also wield it with his right hand, making him ambidextrous, a trait he shares with Roxas. Unlike most Keyblades, this weapon is wielded teeth-forward and shaft-backward.

Like Terra and Aqua's Keyblades, it lacks a keychain. Because it lacks a chain, it is rumored to be a "false" Keyblade; however, this may only be speculation.
