The Sage Art: Storm Release Rasengan is a high-detail, cel-shaded spherical energy construct with a dynamic, swirling core that resembles a miniature storm. The outer layer is smooth and translucent, with a vibrant blue hue that gradients into a lighter, almost white center, emitting a soft glow. Inside, intricate, lightning-like patterns crackle and move, giving the impression of contained storm energy. The Rasengan is proportioned to fit comfortably in a character's hand, with a diameter that suggests concentrated power without being overly large.
