Norris uses SunShower.
|Description||Fire aura in the air to cause a rain of bullets.|
SunShower (オーラレイン , Ōra rein, lit. Aura Rain?) is a Yellow tech used in Chrono Cross. After acquiring 15 boss stars, Norris learns to fire multiple aura-shots into the air to rain down on all opponents on the battlefield.
The Sun is a yellow star that sits in the center of Earth's Solar System. "Shower" describes the volley of bullets fired upon the targets. Since Norris is also a Yellow Innante and wields Guns as weapons, the combination of Sun and Shower seems appropriate.
