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 at its center, surrounded by a dynamic, boiling red-orange aura that simulates the intense heat and energy of boiling water. The surface is smooth yet constantly in motion, with the chakra appearing to bubble and evaporate at the edges, giving it a volatile, explosive look. The overall shape is spherical but slightly irregular due to the boiling effect, with the energy visibly pulsating and expanding as if barely contained.
