My wife's sisters want me to make a harem?!

“A few wives is normal for an Overlord like you,” my wife’s sister said.

Minato was just an ordinary guy. He ran a small shop and lived a quiet, happy life with his wife. If everything had stayed normal, he would’ve grown old peacefully and died satisfied.

But nothing about his wife was normal—she came from another world… and she had fox spirit powers.

Even their married life wasn’t ordinary. What should’ve been a simple relationship turned into something closer to dual cultivation, and somehow, Minato ended up becoming an Overlord because of it.

And just when things couldn’t get any stranger… her sisters started falling for him too.
