Anime Shark in a Submerged Lost City

An anime-style shark protagonist swimming through the submerged ruins of a lost city. A sleek great white with large, glossy anime eyes and a determined grin. Surrounding ruins: moss-covered columns, broken statues, coral arches, seaweed banners, and drifting lantern jellyfish. Bioluminescent orbs and sunbeams cut through blue-green water, casting dramatic highlights. Cel-shaded coloring with bold outlines, vibrant gradients of blue, teal, and gold. Dynamic three-quarter view from below, with motion lines and bubbles to convey speed as the shark navigates through arches and staircases of the sunken metropolis. An atmosphere of mystery and adventure, like an underwater treasure hunt.
