Plot
In the magical fantasy world of Alneath, the villainous Demon Lord Veltol Velvet Velsvalt was slain in battle by the hero Gram. 500 years later, his subordinate Machina Soleige uses magic to revive Veltol. During his time away however, Alneath underwent a catastrophe known as the "Fantasion" when it merged with the industrial world of Earth in the year 2023. This resulted in prejudice between various races, the collapse of national boundaries, and wars between newly established city states. After the wars, relative peace broke out, and Alneath's magic was combined with Earth's industry to create magical engineering known as "magineering". Veltol is revived in the year 2099 in the city state of Shinjuku (formerly Tokyo), and together with Machina and her hacker friend Takahashi, he attempts to regain his power and once again attempt world domination.

Veltol is a villainous immortal demon lord originally from the fantasy world of Alneath whose ambition is to rule the world. Slain in battle by the hero Gram, he does not completely die and is reincarnated by his subordinate Machina 500 years later in 2099, by which time Alneath has merged with Earth. Veltol decides to conquer this merged world, but is now powerless due to his magic abilities coming from belief from his followers. He thus works with Machina and her friend Takahashi to rebuild his following.

Machina was one of Veltol's "Six Dark Peers", his most trusted followers, who has the ability to use fire magic. She also used magic to revive Veltol to life and is his most loyal follower. With Veltol having lost his magic powers, he moves in with Machina after he is revived.

Voiced by: Daisuke Namikawa (Japanese); Dio Garner (English)
Gram is a hero from Alneath who 500 years ago defeated Veltol in battle, resulting in him going into his long sleep until he was revived by Machina.
