After the cataclysm, the continent of Terra lies beneath a wasteland sky, crawling with mutations.
Xiali and Noah set off on a carefree trip around the world in a magic-tech RV that can be upgraded without limit.
They thought it would be a sweet, intimate trip for just the two of them, but the "local customs" they encounter along the way gradually start to feel... off.
In the frozen ruins, they casually pick up a broken-down, expressionless mechanical girl, who becomes the RV's dedicated driver.
In the Fallen Holy City, they happen to blow up a cult and spirit away a proud but softhearted, down-on-her-luck young lady, upgrading the whole crew's cooking skills in the process.
In the cyberpunk ruins, they dig a socially anxious hacker out of a cardboard box, and the convoy gains a radar screen.
At the Evernight black market, they run into a lunatic assassin who even kills her own people. This time, the other woman refuses to get in the RV...
Readers: "Wait! Why does your RV have more and more people in it the farther you drive? You scooped up every featured girl from the gacha pool and brought them along?!"
Xiali, sounding completely justified: "Huh? What's wrong with having a few more pretty girls along for the trip?"
Noah, coolly adjusting her glasses: "Just so we're clear, the only owners of this RV are her and me. Everyone else, pay your lodging fees."
