【OVERLOAD】Overlord-Inspired Opening Theme | Original Metal Version [MV]

I created an original heavy‑metal arrangement inspired by the light‑novel series Overlord, writing both the lyrics and the composition myself. The track captures the dark fantasy world of Ainz Ooal Gown and the Great Tomb of Nazarick, and I used generative AI tools such as Stable Diffusion and MidJourney to produce the accompanying visuals. At the end of the video I share the base prompts I used for character creation, giving viewers insight into the AI process behind the artwork. The piece is entirely self‑made, with all music, lyrics, and video production handled by me.
