Wang Zhao is an ordinary person living in an ordinary city.
One day, he wakes up having transmigrated into the world of Genshin Impact, during the Archon War.
Damn it, other transmigrators get cheats and a System as soon as they arrive. How come I got nothing?
He tries calling out for a System, and that one shout sets the entire Archon War abuzz.
"Invincible System of the Myriad Worlds. I'll protect you from now on, sis."
The Raiden sisters are my subordinates? All of Inazuma is shocked.
I arrive in the world of Dragon Raja and become a Dragon King?
I arrive in the world of Attack on Titan and join Eren in the Rumbling. In the world of Uma Musume, I become a legendary racehorse...
In the end, he'll sweep through other worlds and gradually become the Lord of the Worlds.
Note: The protagonist has a harem (probably?). Sorry if that's not your thing! (Most importantly, I don't know how to write romance. I'm hopeless at it.)
Also, the plots of all the worlds in this story will be heavily altered. I'll explain when I write about each world, so don't worry. If you can't get into it, please drop it early. Sorry. (After all, if I write Barbatos as a woman, won't the Barbatos fans who only support him try to kill me?)
Character concept art - Dark Kite
Here are three concept art images of Dark Kite. Take a look and see which one you like best. They're drawn by AI; I don't have that skill. The first one has wings on its head but not on its back, and it looks a bit mature. The second one has wings on both its head and back, and it's a pure, innocent girl (or maybe a loli? It's hard to tell). The third one has wings on its back but not on its head; this one is definitely a pure girl, no doubt about it. Here's a note about wing display: it's selectable; you can show them whenever you want or hide them when you want. The purpose of this post is to select the Dark Kite in everyone's hearts. If no one comments by chapter 40, I'll just have to figure it out myself (sadly).
