(The films’ titles are also the titles of the first two volumes in Kugane Maruyama’s original Overlord light novel series.)
The manga is a gag comedy series based on Kugane Maruyama’s original Overlord light novels.
The series celebrates the anime’s compilation films, and the title is a play on Overlord: Fushisha no Ō (Overlord: The Undead King), the title of both the light novel’s first volume and the first compilation film.
Overlord: Fushisha no Ō will open in Japan on February 25, and Overlord: Shikkoku no Senshi (Overlord: The Dark Warrior) will open on March 11.
