Overlord - OP

A red flag with a green and gold emblem flutters in the wind against a blue sky, then the scene cuts to a group of diverse, fantastical characters standing on a rocky outcrop beneath a cloudy sky, with a large red flag held aloft by a central figure, while a title card with Japanese text and the name "Naoyuki Hion" appears in the center, followed by a black screen with a white logo and text.
