I Married the Second Male Lead After Reincarnating - Chapter 22

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.

On one spring evening when I was eight years old, I, Erica, Duke of Aurelia’s daughter, realized something.

I was reincarnated into another world, and I’ve brought the Horadric Cube from Diablo II with me.
Being a knight is cool and all, but being a wizard is pretty neat as well.
So, which one will it be?

Growing up in the harsh conditions of the Barrom clan where magic and power reigned supreme, he weathered though humiliation and schemes. Knowing that he wanted to be the oppressor than the oppressed, he began his conquest. Not averse to betraying or scheming, Lucius made use of his allies as mere pawns to be sacrificed.

Learning that a powerful artifact lost eons ago was hidden in an ancient ruin, Lucius betrayed and sacrificed one of his closest people, his lover without hesitation.

Coming to his senses he finds the world to be completely different where the magic of his previous world did not exist, but what did was ‘Gifts’.

Witness how he learns about the world, gains power and reigns supreme against all odds becoming the Demonic Sage.
