J-Novel Club releases the novel and manga in English and describes the story as follows:
“‘Level up even while offline’?! That’s not a game on ‘easy mode’—that’s just an AFK game!” The online game Yamada Kenichi had been playing religiously is shutting down its servers, leaving him with a void in his heart.
He looks for a new game to fill it, but everything he finds is way too easy. The kind of game he likes—the kind punishing enough to make players want to spend thousands of hours on it—just isn’t around anymore.
“What’s this? ‘You are invited to a game that will never end.’” Kenichi stumbles upon an untitled game, one promising incomparable challenge with unprecedented potential. Without hesitation, he selects the “Hell Mode” difficulty.
Lo and behold, he finds himself reincarnated in another world as a serf! Now called Allen, he sets out to unlock the secrets of his mystery-laden Summoner class; without the convenience of walkthroughs, game guides, or online forums, he must grope his way to the top of his new world!
