a drawing of a magical girl with anime aesthetics who is an idol with long white hair and cat ears and tail, wearing a short skirt and a modern top with her belly exposed and showing some skin, with a microphone in his hand singing, The dress is very striking and colorful in blue and black tones, with white ears and tail, and the hair has soft light blue highlights, On her neck she has a necklace with a silver heart-shaped plate, In the background there are lights and sparkles as if I were at a concert
