The image is of two people dressed in costumes from the anime Fullmetal Alchemist, posing in front of a rainbow-colored wall. The person on the left has short black hair and is wearing a blue military-style uniform with white trim, fishnet stockings, and black high heels. They are standing with their right hand on their hip and looking at the other person. The person on the right has blonde hair styled in a ponytail and is also wearing a blue military-style uniform with white trim. They are kneeling down and gesturing towards something off-camera. In the background, there are several people sitting or lying on the floor behind them. The wall behind them is covered in colorful squares of different colors, creating a rainbow effect.
