Ventus

ヴェントゥス, Ven

Ventus, also known as Ven, is one of the main protagonists in Kingdom Hearts Birth by Sleep and Kingdom Hearts Birth by Sleep Final Mix. His name means "wind" in Latin, similar to how Sora's name is Japanese for "sky". He was a Keyblade wielder before Sora ever became one, and was apprenticed to both Master Xehanort and Master Eraqus. He is the youngest of the trio formed by Aqua, Terra, and himself. Ventus eventually gets the darkness extracted from his heart unwillingly, which leads to the creation of Vanitas, a being of pure darkness. Later on, Ventus lives a quiet life and enjoys time with his friends, though due to several circumstances, he must begin to stand up for himself and become stronger. The official Japanese website refers to Ventus as the "Swift Wind Returning to Bonds" (絆巡る疾風 Kizuna Meguru Shippū?).
