Isekai Maou to Shoukan Shoujo no Dorei Majutsu - Volume 1 Chapter 1.04

Suddenly appearing in a different world, it looks like I got caught up in a Hero Summoning. And of course, I’m not the Hero, but it’s another guy……and while being very cautious and scared of the cliche of the cliche-like development, I was thrown into the maelstrom of war……or not.

The Demon Lord? It was defeated a thousand years ago. Hero? He’s just the main actor in a festival. Nobles? They’re kindly taking care of us. The Demon Race? They have good relationships with Humans. Wars? It’s already 800 years since the last one. Monsters? The Guild and Order of Knight are taking care of them. Return to Earth? It is eventually No-Risk.

What I’m planning after being caught up into this? I’m gonna enjoy the life in a different world as much as I want to, go on a cultural exchange and sightseeing, and after experiencing the festival that is only held once every ten years……I shall go home safely.

The other world was――at Peace.

A kind world where the three races, the Spirit World’s Magical Races, the Celestial World’s Divine Races, the Mortal World’s Human Races, they are kind neighbors to each other, with everyone living a peaceful and fulfilling life.

But although I wished to peacefully spend a year before my return, for some reason, the heavyweights of this world keeps gathering around me, and……

In the year 2057, the world has become a corporate-run utopia for the super-rich, and a hellhole for all the rest. Catherine 'Cat' Leblanc is an orphan that is about as far from super-rich as one can be. When the Incursion alarms start blaring and the sky starts raining hungry xenos, it's just another blemish on an already piss-poor afternoon. A cyberpunk magical-girl alien-invasion LitRPG.It’s exactly as wild as it sounds.

After a vacation, when she returned to her country she caught her fiancé cheating. She angrily left and disappeared.

Five years later she returned with her talented kid. Afterwards, her son participated in the piano competition. Unexpectedly her son actually came looking for his father.

“The camera on this side, take me to take a look! My name is Xiaoxi my mommy is called Tang Siyu and she’s very pretty! I’m four and a half years old this year. I’m looking for my father, you probably look like me, please be sure to contact me, oh!”

After that, he was gone from the front of the camera again and said, “Oh, I’ll wait for you!”

In the background, a woman became mad. A few days later, a mysterious man came to their doorstep and claimed to be Little Xi’s father.

Tang Siyu looked at this tall and handsome man, who her son was a carbon copy of, and then became angry.

Five years ago, the bastard who pinned her down was him?
