And monsters—inside and out.Now she’s fighting the Shikiban: creatures born from blood, madness, and buried secrets. But the deeper she goes, the more she begins to wonder...What if she’s one of them?Power always comes with a price. And Reika is about to pay it in full.

Mysterious anomalous biological metals have polluted the world, and the world has undergone tremendous changes. Metal sickness is like a key that opens the door to evolution. Under the tide of evolution, there are no innocents.

The choice is up to you, do you want to be the surviving ants after the fire, or do you want to risk your life, step on the glorious long steps to the gods, and glimpse the supreme glory of the mother goddess?

…

Touch the totem in your heart, follow the inspiration, and step on the long steps of ascending to God:

[Amphibians] → [Atlantic Glory] → [Ningen]…

[Eight Arms] → [Nightmare in the Sea] → [Deep Divers]…

[Eagle Eye] → [Owl Ghost of the Night] → [Jersey Demon]…

[Living Dead] → [Grave Digger] → [Death Ferryman]…

…

“On that day, the world was polluted, and I was the source of pollution. Human desires are endless, desire is the best food on the way to evolution, and I am the embodiment of desire.”
