The Sage Art: Boil Release Rasengan is a vibrant, swirling sphere of chakra with a dynamic, boiling effect at its core, resembling superheated water. The outer layer is a translucent, glowing blue with steam-like wisps emanating from the surface, while the inner core pulses with a fiery orange-red hue, creating a striking contrast. The Rasengan maintains a perfect spherical shape, approximately the size of a basketball, with the chakra visibly rotating at high speed, giving it a sense of immense energy and motion. The surface is smooth yet appears to ripple like boiling liquid, with occasional bursts of steam adding to its volatile nature.
