- "My friends are my power... and I'm theirs!"
- —Ventus to Vanitas before their final battle
Ventus, also known as Ven, is one of the main protagonists in Kingdom Hearts Birth by Sleep. From the view of the story, it is revealed that he is a Keyblade Wielder before Sora and has a strong bond to him, even though they only ever meet through their hearts. Of the trio formed by himself, Terra and Aqua, he is the youngest of the three.
His name means "Wind" in Latin, and Sora's name in Japanese means "Sky". The two are connected, as Sora's heart makes contact with Ventus's injured heart, shortly after the creation of Vanitas, to fix his Awakening station, and at the game's ending, Ventus's heart merges with that of Sora, thus granting him the ability to wield the Keyblade. For this reason, Sora's Nobody, Roxas, takes on Ventus's appearance.

Story
Kingdom Hearts Birth by Sleep
Four years before Aqua and Terra have their Mark of Mastery exam, Ventus served as an apprentice to Master Xehanort, as part of the elderly Keyblade Master's plans to forge the legendary X-blade. However, Ventus proved to be a poor candidate, and when he refused to use his darkness to fight several Neoshadow Heartless in the Keyblade Graveyard, Master Xehanort finally lost patience with him and used his own Keyblade to extract the darkness from Ventus' heart, forming a being of pure darkness who is then named "Vanitas" by Master Xehanort.
Unfortunately, the process left Ventus in a comatose state, with his broken heart of pure light slowly fading out. Master Xehanort, disguised in a Black Coat, then took Ventus to the Destiny Islands to allow him to live out his last days peacefully. Ventus is sent to the Dive to the Heart, where he comes in contact with the heart of a newborn Sora. After a brief discussion, Ventus' heart connects with Sora's, mending his broken heart and allowing Ven to stay alive until he someday becomes strong enough to repair the damage by himself. Ventus then summons a Keyblade and shoots a ray of light into the sky above, much to Master Xehanort's surprise.
Following these events, Xehanort brought Ventus to Land of Departure, where he could train as an apprentice to Master Eraqus. Terra and Aqua met Ventus with open arms. However, when Terra asked Ventus about his past, he screamed out in agony, eventually falling unconscious. Eraqus revealed that this was because Ven had lost his memories. Afterwards, he remained asleep for some time. As he slept, Aqua kept watch over him, to keep him safe. Some time later, Ven woke up. Overjoyed, Aqua quickly alerted Eraqus and a worried Terra about Ven's recovery.
It was then that his heart began to heal and he started to form strong bonds of friendship with Terra and Aqua. During a training session, Ventus loses humiliatingly, but Terra and Aqua reassure Ven that he was getting stronger. As time went on, Terra and Ven grew close, forming a brotherly bond. Terra even went so far as to give Ven his wooden training Keyblade and recite a mock inheritance ceremony. Together, the three of them shared the same dream: to become Keyblade Masters.
Years later, Ventus awakes to a meteor shower and hurries out to look at the stars. Later, both Terra and Aqua join him. When Ven asks about stars and the light, Terra explains how each star is another world and compares the light to Ven, who doesn't understand. After a brief spat between the two boys, they, along with Aqua, spar in order to prepare for the Mark of Mastery exam the next day. Following their workout, Aqua gives both Ven and Terra good luck charms and tells them the story behind the charms. The charms, also known as Wayfinders, were gifted with a powerful magic that formed an "unbreakable connection". Upon receiving the charms, Ven and his friends return to their castle for the night, eagerly awaiting the exam.
However, things don't go smoothly. During the exam, Master Xehanort rigs the test, and the orbs of light attack Ven and his friends. Together, the three fight off the orbs, and the exam continues.
After the exam, it's clear that Ventus has earned the interest of Master Xehanort and his apprentice, Vanitas. Though their intentions are rather ambiguous at the time, Vanitas decides to give Ventus some incentive to leave his home. When Vanitas appears in Ven's room, he leaves dark hints of Terra's fate and how he'll "become a different person". Ven becomes very defensive, telling Vanitas that he doesn't know the first thing about Terra. However, once Vanitas leaves, via Corridor of Darkness, Ven hurries out to find his friend in hopes of giving him a warning.
Unfortunately, Ven arrives much too late, as Terra leaves to go on his mission. Left with no other choice, Ventus leaves his home and begins a journey of his own.
He visits a number of worlds and builds new friendships along the way. In Dwarf Woodlands he helps Snow White escape the woods and guides her to the Dwarfs' home. There, he learns that Snow White encountered Terra and immediately tries to get to the bottom of things. After facing several more Unversed along the way, Ven encounters the Queen in the form of an old lady, and she tells Ven that Terra threatened her with his Keyblade. Refusing to believe this, Ventus leaves in hopes of finding Terra, wondering what's gotten into him.
Then, in Castle of Dreams, Ven befriends Jaq and Cinderella. Though Terra isn't there, Ven still lends a hand, helping gather supplies for Cinderella's dress, and even facing Lucifer. When the dress is complete, Cinderella thanks Jaq and Ventus, and the two talk about their dreams. It's here that Ven decides that his dream is to become a Keyblade Master-- the dream he and his friends all share.
It's in Enchanted Dominion that Ven gets another clue regarding Terra. After freeing Princess Aurora's heart, Ven encounters Maleficent. Maleficent reveals that Terra helped steal Aurora's heart, but Aqua arrives just in time to convince Ven otherwise. She then asks Ven to go home with her, but he refuses, remembering the cryptic warning left by Vanitas.
Coincidentally, Ven encounters Vanitas again after leaving Enchanted Dominion, and he follows him straight to the Keyblade Graveyard. There, Ven tries to get some answers out of Vanitas, who simply restates what he said before, that Terra will be gone forever. The two battle, but Vanitas easily outmatches Ven and nearly kills him. It's not until King Mickey arrives, that Vanitas is defeated. Upon his defeat, Vanitas tells Ventus that he's on probation and disappears, leaving Ven and Mickey alone.
The two introduce themselves to one another, and Mickey tells Ven about the Star Shard. Apparently, it allows him to travel to different worlds, but he still doesn't know all of its secrets. Shortly after, the Star Shard sends the two of them both to Radiant Garden, and Ven tries to follow Mickey, only to be in
