Sun Flame: A Flame yellow in color. Sun Flames hold the abilities of stimulation and augmentation, commonly described in the manga as Activation.

This ability is good for fulfilling support roles such as healing and strengthening individuals. But that same characteristic also makes it difficult to use Sun Flames in direct combat.
