The Sage Art: Boil Release Rasengan is a vibrant, swirling sphere of chakra with a dynamic, boiling effect that mimics superheated liquid. The core is a bright, luminous blue, representing the concentrated chakra, surrounded by waves of orange and red hues that simulate boiling energy. The surface is highly textured with visible energy currents and small, popping bubbles that give it a volatile, living appearance. The overall shape is spherical but with an irregular, turbulent surface that suggests immense power and instability. The Rasengan emits a faint glow, casting light on its surroundings, and leaves a subtle trail of steam when in motion.
