Aqua

Aqua (アクア, Akua) is a Keyblade Master who serves as one of the three playable characters of Birth by Sleep, and the sole playable character of A Fragmentary Passage, a direct sequel bundled in Kingdom Hearts HD 2.8 Final Chapter Prologue. She is also playable during one fight in Kingdom Hearts III. She is a nimble character who specializes in magic attacks while dealing weak physical damage. As the only one among her friends to achieve the rank of Keyblade Master by the start of the game, she is tasked by Master Eraqus to watch over Terra and retrieve Ventus when he runs away from home.[27][28] While attempting to protect Ventus and save Terra from Xehanort's control, she becomes trapped in the realm of darkness, where she remains suspended in time throughout the series while fending off the endless swarms of Heartless. In Kingdom Hearts III, Sora rescues her from the realm of darkness, and she joins him in the final battle against Xehanort.
