Harem in the Labyrinth of Another World

Kaga Michio, who thought he was simply opening the settings menu of a PC game, finds himself inside the game world. Equipment, levels, stats, and settings... Approaching the situation like a typical video game, Michio saves a village from bandits as his first quest. However, Michio discovers that he can't leave this world he believed was just a game by logging out or exiting...

Michio must raise the required funds within five days in order to purchase Roxanne from Alan's mansion. Like everyone else, Michio hunts monsters in the labyrinth and gathers items. However, even with Michio's skills, he won't make enough money in time. An anxious Michio recalls Alan telling him about a way to earn a large amount of money in a short period of time.

Michio stakes his hopes on hunting bandits for bounties and searches for targets around town at night. Though he finds them easily using his skills, they are still human. Conflicted feelings about killing people for money and the fear of needing to defeat his opponents swirl inside Michio. However, with the time limit approaching, Michio steels his resolve and enters the bandits' headquarters!

Michio finally welcomes Roxanne into his party. From now on, they'll be doing everything together. First, they head into town. However, Michio is unfamiliar with the norms of this world and has never spent time with a girl before, and it seems as though the way Michio treats Roxanne is a little different from what she expected...

Michio enters the labyrinth with Roxanne and learns more about the world. He realizes the actions he'd been taking based on assumptions have been terribly inefficient. With the knowledge he learned from Roxanne, common video game strategy, and skill settings, Michio develops a method to efficiently make money.

Michio and Roxanne take on the first floor boss. When Michio sees Roxanne gained a new job from picking up the item the boss dropped, he comes up with a new way to improve his skills in the labyrinth. He uses his knowledge of games to efficiently implement his strategy. When they arrive on the next floor, they find new enemies waiting for them.
