Stormfall

Unreleased Rainstorm (暴風雨) is a Keyblade wielded by Aqua in Kingdom Hearts Birth by Sleep. It, similar to Gaia Bane and Fresh Breeze, made its debut in Kingdom Hearts II Final Mix.

Appearance
Aqua's Keyblade is somewhat similar to the design of Oblivion, with a white and violet color scheme. The teeth on her Keyblade loosely resembles the crown necklace that Sora wears around his neck. The shaft is very similar to that of the Bond of Flame. The guard is white with jagged silver edges, not connecting to the shaft at the top. The keychain links and token resemble water drops.

In Kingdom Hearts II Final Mix, Rainstorm is seen in Xemnas's Chamber of Repose, along with Aqua's armor. Xemnas talked to the armor and the Rainstorm, addressing them as "friend." The Last Episode scenario of Kingdom Hearts Birth by Sleep shows that Xehanort obtained the Keyblade and armor after Aqua use them to get Terra out of the Realm of Darkness, when Xehanort was found by Braig, Dilan, and Ansem the Wise in Radiant Garden they took the armor and keyblade along with Xehanort.
