A spin-off where game company colleagues are transported to another world. What awaits them there...?
The setting is the fantasy world of Elnia. Guest, Orika, and Yuri work at the game company "Arcadia," led by their CEO, Erina. Time has passed since Guest first met Orika, and now they work at the same company. With the addition of their junior colleague Yuri, the four of them—including CEO Erina—spent their days busy with work and swaying between feelings of love. One day, the four of them were out for a company drinks gathering. It was supposed to be just another typical night, venting about work and geeking out over games. Suddenly, a massive magic circle appeared beneath their feet. Enveloped in a blinding light, they opened their eyes to find themselves in an alternate world where swords, magic, monsters, and adventurers actually exist. Yesterday they were making games; today they must survive in a world that is "like a game, but not a game." There are no save points, no loads, and no walkthrough sites. All they can rely on is the knowledge gained from game development, the unique powers granted to each of them, and the bonds the four of them have built. In the office, they were employees and CEO, seniors and juniors. But in this other world, such titles and common sense no longer apply. Can they return to their original world? And in this extraordinary environment, as Guest and the others show sides of themselves never seen before, their relationships begin to undergo a new transformation. —This is the "Isekai Chapter" of the unlikely events that befell the usual four from Arcadia.
