(Flashback)

(KHBBS ost: The Worlds)

(KH Universe: Year unknown)

Space, a vast regions of stars that contain many different kinds of worlds. Which are very special in their own kind of way. The time on each worlds flows very different from one another. There are billions upon billions worlds that have yet to be discovered.

However is it also known as Lanes between (異空の回廊 Ikū no Kairō?, lit. "Corridors of the Skies")

The Lanes Between are a series of "roads" between the worlds in Kingdom Hearts Birth by Sleep that were unlocked by Eraqus. Ventus, Aqua, and Terra frequently use these paths to navigate the worlds. The presence of Darkness is very strong within them, forcing travelers to wear their Keyblade Armor as a safety precaution. To enter the Lanes, the Keyblade wielder raises his or her Keyblade to the sky, and creates a portal leading into the Lanes, appearing somewhat similar to the Dark Corridors. Upon opening the way, they usually call their "Keyblade Glider" and use it to enter. The Lanes resemble the Corridors of Darkness, but with a color scheme closely resembling the Aurora Borealis.

Currently we find a feminine figure in blue and purple Keyblade Armor riding the same colored bow-shaped Keyblade Glider in the vast sea of stars.

This woman's name is Aqua, who is seventeen years old and was currently named a True Keyblade Master after passing the Mark of Mastery Exams not too long ago. Quite the prodigy is it she? She just recently left a world called Destiny Islands, which had tree that grows star-shaped fruit that she modeled from the Wayfinders that she had created for herself and her two best friends.

But that's not the only thing special about that world.

While she was there, she met two young boys almost the same age as the young girl she met in Radiant Garden named Kairi, who remind her of Ventus and Terra. They were Sora and Riku. After measuring the strength of their hearts, she going to make Sora her successor in wielding the keyblade some day but she seeing how Terra named Riku his successor she choose not to because she doesn't want them to fight like her and Terra. So instead she had Sora made her promise to protect Riku no matter what and bring him back to the light should he fall into the abyss. Hearing how Sora made the promise to her, she affectionately rubbed their hair and left destiny islands to look for Ventus and Terra to hopefully patch things up between them and become friends again.

This bring us to our current situation, as Aqua was gliding through space with determination, she came across another bright light similar to the one that sent her to Destiny Islands but yet different due to the fact that it was warmer and shining bright like the sun.

Curious to see where it leads, she flew toward the light and the next thing she knows she was in a world kinda of like Destiny Islands but was a large village of some sort filled tons of people and other in the distant was a mansion and mountain with four heads on it.
