Earth's civilization and more than forty other intelligent civilizations are collectively transported to the same region of the universe. At the same time, each civilization's home planet splits open with anywhere from a few to hundreds of spatial rifts, each leading to a world governed by a different power system: magic, spiritual energy, faith, Gälägeimu...
I was an ordinary person on Earth. I closed my eyes, opened them, and found myself in this world. I'm certain this isn't the Earth I came from. Then, by chance, I awakened a unique Gälägeimu System and the talent [Learn by Doing], which lets me grow stronger through quests and studying.
But none of that matters. This is a high-martial world, and I'm terrified they'll treat me like a lab rat. I want to go home.
Damn it, I just want to go home! Why are you all being so nice to me? The Gälägeimu System hasn't even kicked in yet. I really just want to go home!
