A Certain Slow Player

A man who has chosen a different, slower path. Most active players who haven't given up on completing the game go to higher floors soon after they get unlocked, if not immediately. However, the main character realizes that there must be a reason each world is so large and detailed. There must be a reward for exploring a world, even if it has been cleared after defeating the main boss monster. And so, he decides to stay and do what he has always loved to do in video games, explore and discover. To embark on an epic adventure. Or maybe he was simply scared in the early stages of the game. This is a deadly game after all, one in which millions are trapped.
