I Transmigrated by Accident, and Now It’s Just Me and the Girls in the Apocalypse

[Apocalypse] + [mutation] + [natural disasters] + [awakening] + [multiple heroines] + [building a faction]. A spaceship from an alien civilization crashes by accident, and a special infected specimen known as Black Devil quickly spreads across the world. The Supreme Archbishop orders the immediate launch of the “Planetary Restoration Plan.”

Hold on, hold on… What does any of that have to do with me? This is such a pain. I failed to win over my beloved, then accidentally transmigrated to the Apocalypse and met a chattering little System, who turned out to be female. I went into town to seek shelter, and a rich young lady claimed I was her fiancé. Then one day, my beloved showed up in the Apocalypse and sneered coldly: “They all say you can fight. How about a match? If I win, you’re mine. If you win, I’m yours. Deal?”
