The design of the Keyblade follows 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 the cresting wave. The hilt has two heart-shaped openings, and the Keychain is Aqua's Wayfinder. The handle and chain are both an ivory color.
"Bright" reflects Aqua's association with Light, while "crest" refers to the crest of a wave, matching the Keyblade's design.
