The Sage Art: Lava Release Rasengan is a powerful, swirling sphere of chakra infused with molten lava, creating a dynamic and destructive energy ball. It features a core of bright, glowing orange and yellow hues, representing the intense heat, surrounded by a turbulent, dark red and black lava exterior that crackles with energy. The surface is highly textured, with visible lava flows and chakra sparks, giving it a volatile and organic appearance. The Rasengan maintains a spherical shape but with an uneven, boiling surface that suggests constant motion and instability.
