Everyone wants superpowers, including Alden Thorn.But even if he's lucky enough to be one of the few humans granted magical abilities by the extraterrestrial System that's been running things on Earth for decades, his goal of being a battlefield support hero is still a long way off.He's got determination on his side and maybe a murderous alien desk clerk, too.The universe is a complicated place. Alden's about to meet it.

One day every human on the world suddenly receives a mail claiming to enact the World Salvation Project. Half in doubt Kurosaki Shion, a diligent university student and loner, follows the mail’s instructions, becoming one of a million Demon Kings governing his very own Domain in the new world.

*** This is a post-apocalyptic story containing many fantasy elements. It is a somewhat dark tale following Shion as he grows while aiming for the unification of the all too sudden new world. It has many game-elements bolstered by strategical thinking while at the same time providing funny moments and romantic encounters.

I had transmigrated into my favorite game, as an extra who died before the story even began.In a world where Sigils dictate power, I found myself in the body of a boy who had already died on the battlefield.Yet, as I drew breath in his place, his Sigil changed. A power never meant for him, never meant for me.Kidnapped by a shadow organization that didn't exist in the game, I spent three years in the dark, forced to learn under a so-called teacher.I move forward, not as the extra I was meant to be, but as one who chooses their own path. A path to supremacy.Yet the deeper I walk, the more I realize… this world holds secrets that game had never shown.-----------------Additional tags:[Sword Companion], [Hidden Identity], [Artifact Power], [Slow Reveal], [Secret Society], [Survival]
