Revive Rome: Wait! Why not make the empress fall in love with me first? - Chapter 27 - 19 Because You Are Essentially a Good Person

In the legends that were told, ten thousand years ago the twelve demon kings wreaked havoc upon the world, almost completely destroying it. Ten thousand years later, the late arriving Bella discovered that she had been screwed over by her reincarnation, the ranks of the Saviors are already filled and she has to change teams in order to pass the days. Having her gender changed into a beautiful girl… she endured that, not being able to join the righteous side and obtain cheat abilities… she endured, but what she could not endure, was that the world that she had transmigrated to was toxic beyond belief. No one here does their rightful jobs properly, be they heroes, demon kings, or creator gods… in fact, Bella felt as if they all had also started with the wrong faction!

Suddenly, the unmarried twenty-year-old Ye Zhizhou had many more relatives, yet it was too late for him to clearly understand the circumstances as he nearly died in a car accident. After that, he somehow managed to survive and was even forcibly bound to a Salvation System.

How is it salvation?

Harems destroy worlds! Preventing a harem will save them!

. . . .

Ok, prevent harems. After seeing the entire system introduction, the corners of Ye Zhizhou’s mouth twitched. In order to return home safely, he decisively began his risky journey—he’d just treat it as if he was playing a large-scale strategy game.

Since then, the people the protagonist would rescue, he rescued first.The businesses the protagonist would make, he made first. The little brother the protagonist would take in, he took in first. The cliff the protagonist would jump off of, he jumped off of first. The gay s*x the protagonist would have, he’d have. . . . Wait wait, can’t do this one, change it, let me change it.

???: No, you can do this one.

Ye Zhizhou (alarmed): Who’s speaking?

???: Your husband.

Ye Zhizhou: . . . .

- Description from novelupdates

As soon as she fell into the world of beastmen, a leopard forcibly took her back to his home. Indeed, Bai Qingqing is at a complete and utter loss. The males in this world are all handsome beyond compare, while the women are all so horrid that even the gods shudder at their sight. As a first-rate girl from the modern world (she’s also a quarter Russian), Bai Qingqing finds herself sitting at the center of a harem filled with beautiful men — at the very peak of existence.

Set on a giant, almost finished bridge between Sadogashima and Niigata. Abandoned by the government, the bridge, and the giant man-made floating island at the center, has become a city of criminals and societal drop-outs.

Set in the same world as Durarara, but 15-20 years later. There is almost no overlap between Etsusa Bridge and the other novels.
