Prism Rain

Prism Rain (レインボウシャワー) is a Shotlock that is exclusive to Aqua in Kingdom Hearts Birth by Sleep. This Shotlock is similar to Ragnarok, but instead of beams of light, it shoots out rainbow-colored beams. A salvo of rainbow-colored orbs are shot out of the Keyblade, extra attacks can be triggered by pressing at the correct time interval to fire additional projectiles.
