Game promotional PV, 15s. Pure 2D Japanese cel animation combined with abstract Editorial MG composition.

[Art Style]
Mysterious lunar eclipse style. High-contrast palette of deep purple, black, indigo, and silver-white, with limited glowing purple accents. Minimal hard-edge cel shading, large solid-color silhouettes, 1–2 shadow layers.
Flat background with only architectural outlines, spires, wires, antennas, and geometric blocks. Integrate lunar phases, eclipses, orbits, star charts, astrology UI, compass, radial lines, scanlines, halftone, and geometric slices.

The entire video feels like a dynamic game poster constantly being broken apart and reconstructed. No realistic 3D space.

[Characters]
Female protagonist: black shoulder-length hair, black uniform, long boots, holding a massive katana, cold and restrained.

Villain: gray long hair, black wide-brim hat, black long coat, elegant and dangerous.
[Storyboard]
0–3s
Black background. A giant purple lunar eclipse appears. The female protagonist’s silhouette stands at the center. Her step causes the moon phase to fracture into geometric rings and star chart markings. Architectural outlines assemble from darkness.

3–6s
Fast camera pan. The heroine moves forward with her sword. Background switches through different lunar phases. Buildings, orbits, and star charts are sliced and reconstructed. Silver-white orbital lines cross the character as the frame flips and compresses.

6–10s
High-speed MG montage. Eyes, katana silhouette, lunar phases, star trails, compass, raven silhouettes, and solar eclipse rapidly overlap. Each beat triggers inversion, geometric bursts, orbital rotation, and purple flashes. No continuous combat, only key poses.
10–13s
Pure black space. The villain sits at the center of a giant lunar ring and slowly raises his head. The moon behind him becomes a complete solar eclipse. Purple halos expand. The heroine’s silhouette appears inside the moon. No direct battle.
13–15s
The solar eclipse shatters. Orbits, star charts, lunar phases, and architecture collapse inward and rebuild into an original game logo.

[Restrictions]
Keep a flat 2D MG style. No realistic lighting, no 3D cities, no realistic perspective, no cyberpunk streets, no continuous fighting. All elements must be graphic silhouettes. Every frame should look like a premium game poster.
