[Prince of Tennis] The Child of God's Evolution

Yukimura Seiichi and Ito Nao were two parallel lines that never crossed.

But! They were enjoying their fun-filled (?) school lives when, one day, they discovered that every night after falling asleep, they were abducted by a mysterious System. It sent them to another world with a Western fantasy setting and a plot revolving around two reverse-harem stories. The male protagonist was determined to win them over, but after failing for ages and being thoroughly fed up with his advances, the peerlessly beautiful man (or woman) transformed into the villainous Boss, constantly throwing obstacles in the protagonist's path and making his journey harder.

This story teaches us: be careful when pursuing someone. Stalking them relentlessly is never a good idea.

Even if you have the protagonist's aura, a peerlessly beautiful person who's had enough of your pestering could turn dark and become a villainous Boss.

After transmigrating as villainous Bosses, their mission is to stop the womanizer and the Mary Sue from building a harem.

In short, they must disrupt all their romantic entanglements and help countless beautiful men and women (as well as themselves, innocent victims caught in the crossfire) escape the protagonists' clutches.

Desperate to get home, they are forcibly bound together as partners and set off on their journey. They strive to adapt to this unfamiliar world, where danger lurks everywhere and pain is felt at 100 percent intensity. Together, they overcome every challenge, keep each other company, learn, grow stronger, and embark on the path to becoming the strong.
