The Sage Art: Boil Release Rasengan is a vibrant, swirling sphere of chakra that combines the traditional Rasengan's spiraling energy with the unique properties of Boil Release. The core is a bright, luminous blue, representing the dense chakra, surrounded by swirling steam and heat waves in shades of orange and red, indicating the boiling effect. The surface is highly dynamic, with the chakra constantly moving and the steam particles dissipating into the air. The overall shape is spherical but slightly distorted by the intense energy and heat, giving it an organic, unstable appearance. The glow from the Rasengan casts a soft light on the surroundings, emphasizing its power and the sage energy infused within it.
