In a dimly lit grand hall, a young woman atop an elaborate, glowing, tentacled machine amidst towering stone pillars.
The image showcases a large, intricately designed mechanical tank with tentacle-like appendages. Atop the tank stands a young female character, dressed in a school uniform with a red ribbon. The tentacles are purple and have a skeletal appearance, emitting a greenish glow. The tank itself is adorned with various symbols and details, including what appears to be a face on the front and a large cannon. The setting is a grand room with tall columns, and the atmosphere is dark and mysterious, with a spotlight illuminating the scene.
