Four anime girls with horns are gathered in a desolate, industrial-looking environment. One girl with blue hair and horns is in the center, holding a weapon. Another girl with green hair is sitting on a ledge to the left, and a third girl with brown hair and horns is seated to the right. A small, bird-like creature in a white outfit is visible inside a vehicle behind them.
