Brightcrest

Brightcrest (ブライトクレスト) is a Keyblade that can be wielded by Aqua in Kingdom Hearts Birth by Sleep.

Aqua obtains the Brightcrest after creating Castle Oblivion from the ruins of the Land of Departure with Eraqus's Keyblade.

Design
The design of the Keyblade goes along with Aqua's water theme by being reminiscent of cresting waves, both along the shaft and at the teeth. Also, Aqua's Wayfinder appears at the top of the shaft within a black circle, surrounded by a cresting wave. The hilt has a butterfly-like shape, and the Keychain is also Aqua's Wayfinder. The handle and chain are both an ivory color.
