Coal and Ash

The protagonist who has somehow been transferred to another world. Looking around, a dilapidated house for some reason. The protagonist of the other world reincarnation has no sense of strength and can only work hard normally. However, in this situation, the only job is to exorcise monsters...

After the protagonist's transfer, they will appear on the streets. The protagonist, who gathers companions to survive, is approached by her. At first, they were two people who didn't know each other, but as they left the country and continued their journey around a few villages, they developed into a relationship of walking together. Is it the invasion of demons, or is it only the two of them saving each other?

The true center of the war between humans and demons due to the invasion of the demon king's army. The human country is only one country... Solaeyu Kingdom is all that is left, and humans are slowly dying out. The domestic security is also the worst, and it is devastated. Many of those who can use magic are leaning towards the demon king's side. Many elves and hunters are also brainwashed by the demon king's army, and the few survivors are captured by the Solaeyu Kingdom. Most of the other world reincarnates were called by the demon magicians, so they eventually become monsters due to the demons that devour their bodies. Demon food is basically provided, but the more you eat, the more demons accumulate, and the spirit becomes polluted. There is no way to completely eliminate the demons, and it is only possible to transfer them to other creatures through body fluids such as blood, or to alleviate the symptoms by ingesting the flesh and blood of holy creatures.

To survive in this world. There is no way to return to the original world, so you have to survive no matter what you do. Whether to return to the Demon King's army or continue a weak resistance. If you return to the absorbing side, how comfortable are you?
