Deep Zeon

A crowd of people dance and raise their hands in a dimly lit, festive environment. The scene shifts to a man with a tattooed arm interacting with a woman in a crowd, then cuts to a dark, ornate chamber where a monstrous, tentacled creature with a skeletal face and a large, toothy maw is shown in close-up, followed by a wide shot of the creature's lair, and finally a close-up of its tentacles moving over a piano keyboard.
