The Sage Art: Boil Release Rasengan is a vibrant, swirling sphere of chakra that combines the traditional Rasengan's spiraling energy with the Boil Release's steam-like properties. The core is a dense, glowing blue orb with intricate, spiraling patterns that emit a faint steam, giving it a boiling effect. The outer layers are less dense, with wispy, steam-like tendrils that flicker and move dynamically, creating a sense of intense heat and energy. The overall appearance is a mix of smooth, polished chakra at the core and rough, textured steam at the edges, with a color gradient from deep blue at the center to lighter, almost translucent hues at the periphery.
