The first version is used by Reborn in his Arcobaleno form. While Leon is in gun mode, Reborn charges a small amount of Sun Flames at the tip of the gun, forming a yellow, sparkling sphere, and then fires. The beam splits into high-speed arrows with homing capabilities that can attack multiple targets at a time. The arrows can also attack the same target altogether, dealing great damage.
Reborn's also used it during the short time his curse is released during his fight with Bermuda von Veckenschtein. Reborn shoots bullets into the ground that emerge later and immediately hits his target.
- The Sun Flames are able to split into more than 10 arrows.
