Picking Up Useless Girls in Apocalypse

The apocalypse has hit hard. Humans found a new gate-like thing in Antarctica and went ahead to work hard and soul for two years to open it. Now due to those stupid scientists, we are facing the apocalypse. Hordes of demons and monsters came out of the door with a horrible purple mist. Now almost ninety percent of the population is wiped out. Demons and their nests occupy the earth now.

If that wasn't the worst part, there's more. How many of us are left, we have to hard to survive. Everyone groups up together to survive. Each person does something important, so the group can go on longer until they can find shelter.

Well, that's what normally happens. But in my case, something miserable happened. If this were not the apocalypse, I would enjoy my time but considering my life is at risk every single moment; I can't help but notice this as you can see the three of them walking behind me, carrying bags, getting all sweaty with their beautiful faces and their perfectly shaped bodies. They look tempting, right? If you think that, then you are not fit to survive the apocalypse.

Let me tell you, my friend, those girls are absolutely useless in terms of anything that requires skills to survive. Unless it's carrying the weight, they can't do anything. And my bad luck, I can't get any better companions to survive this hell.

Luckily I got the support of a system that lets me become stronger every time I kill a monster or demon. But my life isn't getting any easier, is it?
