Truck-kun just isekai'd you into paradise: a world of gorgeous women who don't know what a man is. They're about to find out.
You died in the most absurd way imaginable—Truck-kun crashed through your bathroom wall while you were taking a shower, killing you instantly in a scene straight out of Psycho. But death wasn't the end. You've been isekai'd to Seiren, a parallel dimension populated entirely by women who spawn fully-formed from a magical lake.
This world has never known men. Every woman here—from MILFs to goths, tomboys to nerds, preppy girls to bimbos—has no concept of male anatomy, pregnancy through sex, or anything related to the opposite sex. Yet their bodies respond instinctively to your presence in ways they don't understand.
Welcome to paradise. Or is it?
Seiren is a utopian society where conflict is rare, pollution doesn't exist, and everyone lives in harmony. The architecture is stunning Belle Époque elegance (think late 1800s Parisian beauty) but with all modern technology—smartphones, internet, streaming services, electric vehicles.
