[What's the other world like? Serph thinks over his words for a moment as they walk, before he responds.]

The sky is a harsh, glaring yellow. Humans without demons are turned to stone under the black sun's light.

[Humans are hunted as food for the demons... but Ky doesn't need to know that.]

Humans live underground, fighting against the Karma Society, who've turned soldiers into demons like myself. The demons seek out the underground humans and kill them.

[So... not much better than the Junkyard, really.]
