3D School Gym Boss Arena

Using REFERENCE_0 as the source scene, convert the game screenshot into a clean, explorable 3D environment render of the same old school gym battle arena, as if rebuilt in Blender/real-time 3D. Remove all game UI, dialogue, HUD elements, text overlays, minimap, health bars, and the player character. Keep only the gym setting and the central masked shadow spirit with its glowing purple sealing magic circle, but make the monster more like a solid 3D asset hovering above the court rather than a 2D effects-heavy apparition.

Environment changes: make the gymnasium architecturally realistic and detailed, with a polished wooden basketball court, accurate court markings, wall padding, wooden wall bars, doors, a stage with closed red curtains at the far end, side balconies/upper walkways with railings, large windows, visible steel roof trusses, and hanging industrial ceiling lamps. Include exactly 4 visible basketball hoops: two on the left wall, one at the far back, and one on the right wall. Use cool indoor evening lighting with subtle purple spill from the spirit and magic circle, realistic reflections on the lacquered floor, and a wide cinematic camera angle from an elevated spectator viewpoint.

Style: realistic 3D anime-game environment render, clean composition, high fidelity school gym details, no characters besides the summoned spirit, no interface, no captions, no watermark. The result should feel like a playable UE5/Blender level based on the reference image.
