Brightcrest

Bright Crest (ブライトクレスト) is a Keyblade wielded by Aqua in Kingdom Hearts Birth by Sleep. Aqua obtains it after creating Castle Oblivion from the ruins of the Land of Departure with Master Eraqus's Keyblade.

Design
The design of the Keyblade is reminiscent of cresting waves, both along the shaft and at the teeth. Also, Aqua's Lucky Charm appears at the top of the shaft, surrounded by a cresting wave. The hilt has a butterfly-like shape, and the keychain is also Aqua's Lucky Charm.
