D.E.M.O.N.S: Getting Summoned Weekly isn't so Bad - Chapter 1: A Totally Normal Birthday

The strongest doesn’t need cheats.

Haruka, a high schooler who spends his life as a “loner,” is suddenly summoned to another world with his classmates.

Noticing the god in front of him, Haruka was going to get cheat abilities by picking what he wanted from the skill list so that he could live in the other world――or so he thought, but the skills were first come, first serve.

All the cheat skills were taken by my classmates?!

After not being able to get any amazing skills, Haruka’s “loner” skill made him unable to join any parties. Even in another world, he’ll adventure in solitude.

Haruka, recognizing the crisis of his classmates, decided to secretly help them out while not relying on cheats. He’ll surpass cheats as he walks the path of the strongest――.

Let the curtains raise for the tale about the strongest loner’s attack on the different world!

I am Supreme

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?

PS. Cover not mine, I just found it on google.

I struggled until I was thirty-eight and couldn’t afford a house. I had to pay a gift of three hundred thousand in advance to get married. I lived frugally and frugally for most of my life until my liver was broken. But where was the money? Who made the money?

Jiang Qin, who harbored countless grievances, was reborn at the age of eighteen. The only thought he had when he opened his eyes was to start a business and make money.

The first step is to snatch back the love letter you sent, turn it over, and write three lines in the school belle’s astonished eyes:

You can’t work for anything, and you can stay with a rich woman if you can.

You can make more money if you lose it, but you can make more money if you lose your conscience!

Social animals, never slaves!

As for love? Dogs don’t even talk about that stuff!
