Sora 2
The art is black and white, dark, anime-style. A huge black silhouette of a terrifying monster, on two legs and with strings like a puppet, but black, runs after two little puppet girls on an island. The terrifying silhouette spots the girls, grabs one of them, and throws her with all her might onto the floor. The second puppet girl runs as fast as she can from the terrifying figure, but she's unable to escape. The final shot zooms out on this terrifying island, where the sirens continue to sit and sadly gaze into the distance.
