Anime Submarine Trek in a Dragon's Lair

An anime-style submarine glides into a dragon's lair inside a vast underwater cavern. A sleek retro-futuristic submarine with a glass cockpit, piston fins, and bubbles streaming from its exhaust explores glowing coral and bioluminescent crystals. The cavern walls shimmer with reflections from pools of lava and the submarine's lights. In the background, a majestic dragon coils atop a mound of gold and gems, emerald eyes watching the intruder, wings partially unfurled. The scene should be vivid with bold cel-shaded colors, dramatic lighting, and dynamic perspective—combining underwater ambiance with anime aesthetics and a sense of urgent adventure.
