The Sage Art: Boil Release Rasengan is a vibrant, swirling sphere of chakra with a dynamic, boiling effect at its core, resembling superheated liquid. The outer layer is a translucent, glowing blue with steam-like wisps emanating from it, while the inner core pulses with intense orange and red hues, mimicking boiling lava. The Rasengan maintains a perfect spherical shape with a diameter of approximately 30 cm, and its surface is constantly in motion, giving it a lively, unstable appearance. The energy it emits is visually represented by heat distortion waves around the sphere, enhancing its powerful and volatile nature.
