A dazzling concert climax illustration from an idol anime called "Prism Ladder". Three idol performers stand in a triangle formation at the front of a massive stage, each striking a signature finale pose, microphones aloft. Center idol: silver-white costume with trailing holographic cape mid-billow. Left idol: crimson ruffle dress, one arm reaching skyward. Right idol: cobalt asymmetric jacket, kneeling with fist raised. Stadium: 50,000 glowing fan light sticks in pink and lime green fill every dark corner. Stage rigging: confetti cannons mid-burst, pyrotechnic columns of gold sparks framing the trio. Shot: drone-angle wide shot from front-of-stage, capturing the full scale. Light beams in magenta and white pierce upward through confetti cloud. Color palette: vivid magenta, gold, cobalt, lime green glow, white spotlights. Mood: ecstatic, communal joy at full volume.
