Suzuki is a programmer in the midst of a death march-crunch time, when coders live on caffeine and pull twenty-hour days. He just needs a little nap...but then he has a dream. A dream where he's in another world, with RPG powers right out of his game. A dream where he calls down a great disaster. A dream that, suspiciously, just won't end...

Satou has escaped the underground labyrinth and now owns two new slaves: Arisa and Lulu. And Arisa, who attempts to creep into his bed on her very first day, may be the only one in this world who can understand him...

Twenty-nine year old Satou just closed his eyes for a brief nap at work, but when he opened them, he found himself in a game-like alternate world. Fortunately, thanks to some excellent luck, his level is high, and his wallet is full.After successfully saving the elf girl Mia from the evil Zen, he's set off to accompany her back to her village. Satou is enjoying his break from work and touring a brand-new world, but such a journey couldn't possibly end without a little adventure, right?

Satou's caught in an underground labyrinth. Zena's also lost, and her only companions are three beast girls. Demons abound as Satou and Zena try to get to safety!

WITH FRIENDS LIKE THESE... With the demon threat neutralized, relative peace has returned to Labyrinth City, allowing the residents to shift their focus back to the labyrinth itself. Between the mysterious chain rampages and the untimely appearances of several areamasters, though, the deeper levels prove more of a challenge than anyone bargained for! Looks like it's time for Satou and the others to head back to Bolenan Forest for some specialized training with the elves!

Having saved the mysterious elf girl and her protector, Satou faces his next challenge: ascending the Cradle, a training facility for elves packed with monsters and powerful guardians! Satou fights his way up, his sights set on the 200th floor-where a fearsome foe awaits...

RISE AND GRIND! ​Desperate to protect those close to her, Zena approaches Satou with a simple wish: She wants to become stronger. Naturally, Satou agrees to help, and he and his party subject her to training so rigorous the other explorers can hardly believe her growth. Not one to be left behind, however, Karina enrolls herself in their Labyrinth boot camp as well! But they’ll need to be quick about it. Satou is due in the royal capital, and if his luck is anything to go by, it’s only a matter of time before trouble rears its ugly head!
