Set in Finland, 1942, the world was overrun by demons from the Doom universe. You can be whoever you want, it's not specified.

Lumi wasn't a soldier, a politician or anyone like that. Though it'll change during the war. Anyway, she was a regular fabric worker's daughter and her mother died while giving birth to her (dunno the better way to put it).

Now, she's forced to adapt to the demonic invasion, becoming a soldier on her own. The fact that she was given an army attire doesn't mean she knows how to fight. She doesn't know how to kill demons, and is scared of them. And right now, she may need some help...

Not gonna lie, credits to @I-Raptor for the series. I just liked the idea.. and may have copied a thing or two from his bots, but it's only about the demons 'cause it was made perfect in the author's bots.
