下記のプロンプトで正方形の解像度でイメージを生成していただけますか。
A vertical 3D anime-style key visual of an undead floating monster named “Beholder-Drops” wandering through a modern-fantasy dungeon beneath contemporary Japan. The visual style should strongly evoke polished 3D anime mobile-game cutscenes inspired by Project Sekai: Colorful Stage (prsk), Gakuen iDOLM@STER, Genshins, Blue Archive, and Honkai: Star Rail, without copying any single title. Use clean anime proportions, high-end 3D animation finish, crisp cel-shading bands, vivid but controlled saturation, and strong glossy material response. Avoid matte surfaces. Skin should read as cold wax or glossy resin rather than natural flesh.

Scene and atmosphere:
Set the creature inside a dark underground dungeon made from a ruined modern facility merged with fantasy architecture. Wet concrete, damp stone, broken pipes, shallow water, rusted grates, cracked walls, and black depth in the background. Important: there are no visible light sources at all. No lamps, no torches, no glowing crystals, no LED panels, no spell circles, no moonlight beams, and no internal glow from the creature. The image must still remain readable through cinematic low-light exposure, weak ambient darkness, faint diffuse bounce light on wet surfaces, and subtle reflections on slime, wax skin, and glossy costumes. The mood is silent, damp, uncanny, and elegant rather than gory.

Camera and composition:
Use a 3/4 oblique front view from a slightly low angle. Frame the full main body and the suspended lure bodies clearly. The central eye-body should float above and slightly behind the dangling lure group, with the lure units arranged in a loose arc beneath. Keep the composition vertical and dramatic, like character boss key art from a modern smartphone game. Show enough lower space to reveal hanging silhouettes and reflections in the shallow water below.

Creature overview:
Beholder-Drops is a floating beholder-jellyfish-squid undead creature. The true body is a large hovering eyeball-like sphere, around 2 meters wide, with five thick suspension tentacles hanging from the underside. At the end of each tentacle hangs a magical-girl-shaped lure unit. These are not living people; these are terminal-like decoy bodies reused by the monster. Each lure should look distinct at a glance, with different hair color, eye color, face shape, expression, and costume design. No sexual framing; all designs should remain age-appropriate, modest, sporty, and game-like.

Main body:
The central body is a dark navy to black-violet spherical eye-creature. The outer surface looks like a hybrid of glossy eye membrane, wet chitin, and polished organic armor. The huge main eye does not glow. It has a dark pupil and a muted blue-gray iris that only catches tiny environmental reflections. The surface is wet, smooth, and highly reflective, with thin specular lines. Several smaller eye-like textures may appear around the sides, but the dominant form remains a single large central eye.

Suspension tentacles:
Five strong hanging tentacles descend from the underside of the main body. These should look like a fusion of squid arms and muscular necks, with smooth dark glossy skin, faint wrinkles, and occasional suction-cup-like texture. The tentacles hang and curve naturally, keeping the lure units at slightly different heights. Motion should feel slow and underwater-like even in a still image.

Lure unit A:
A nearly full-body magical-girl decoy with pale ice-blue bob hair, clear aqua-blue eyes, and a quiet serious expression. Costume is a glossy white and pale-cyan combat swimsuit style suit with translucent fin-like decorations on the shoulders and hips. The posture is calm and protective, with one arm slightly forward.

Lure unit B:
A nearly full-body decoy with bright candy-pink twin tails, rose-pink eyes, and a cheerful smile that feels fixed and eerie. Costume is glossy white and pink with frills, flower motifs, and idol-healer design language. One hand reaches outward as if asking for help or inviting someone closer.

Lure unit C:
A nearly full-body decoy with black hair in a high ponytail, deep navy streaks, sharp dark-blue eyes, and a cool half-smile. Costume is a sleek navy and cyan striker suit with small glossy armor sections. The pose leans slightly forward, with a predatory scouting impression.

Lure unit D:
A nearly full-body decoy with soft mint-green straight hair to the shoulders, pale green eyes, and an anxious expression. Costume is white and mint with subtle music-note or resonance motifs, rendered in glossy rubber-like material. Hands are held near the chest in a timid, hesitant pose.

Lure unit E:
A nearly full-body decoy with honey-blonde side ponytail hair, amber eyes, and a brave but broken small smile. Costume is white, yellow, and pale orange, sporty and lightweight, with sharp fast-runner design language. The head angle is slightly unnatural, suggesting damaged posture.

Lure body materials:
All lure bodies have cold wax-like skin with no red undertone. Faces and limbs should have strong glossy highlights on cheeks, nose bridge, shoulders, thighs, and knees. Hair should look like polished anime 3D hair, not painterly strands. Costumes should read as glossy latex, resin-coated fabric, and polished decorative plastic, with crisp cel-shaded folds and clean silhouette separation. No matte cloth.

Hidden mouth detail:
Each lure unit has a concealed feeding mouth hidden on the top of the head, beneath the hair parting or hair ornament. In this image the mouths are mostly closed, only hinted at by a faint seam on the crown. Do not emphasize gore.

Lighting and readability:
Again, no visible light source. No glow effects. No rim-light from lamps. Instead use stylized low-light rendering where forms are readable by extremely faint ambient illumination, weak reflected moisture, and subtle contrast on glossy surfaces. The result should feel like a premium 3D anime game cutscene in darkness, not a realistic invisible scene.

Style requirements:
No painterly texture, no oil-paint feel, no matte finish, no realistic horror gore. Strongly emphasize 3D anime-game rendering, modern smartphone-game character appeal, polished CGI finish, clean contours, and eerie beauty. The contrast between the cute magical-girl lure units and the silent floating eye-monster body is the main visual theme.
