Yen Press is releasing the novels in English, and it describes the story:
Fused Era Year 2099—Shinjuku. The dazzling prosperity of this massive city-state conceals a lurid darkness just beneath its surface. It is here—in this megalopolis that represents the pinnacle of human development—where the legendary Demon Lord Veltol makes his second coming. To rule this brave new world, he will have to take hold of the future for himself!
Kadokawa published the first novel volume in January 2021 and the second volume in April 2021. Yen Press released the second volume in June 2022.
Kiiro Akashiro is drawing a manga adaptation of the novels in Kadokawa‘s Shōnen Ace+ website.
