Masuda Keima just wants to sleep. Too bad for him, he’s been pulled from sweet dreams and comfy sheets into a fantasy dungeon in another world! Not only is he charged with protecting it, but failure to do so will cost him his life. His only guide is the personification of the Dungeon Core, Rokuko–but she’s a moron who can’t even figure out how to drive away a group of bandits. If Keima ever wants to get some quality shut-eye again, he’ll have to take over running this dungeon himself! (Source: Seven Seas Entertainment)

My name's Karina—or at least, it is now! I used to be a nondescript, run-of-the-mill Japanese salaryman until I was whisked away to a divine realm where the Goddess of Time and Space told me I'd be living a new life in a new world—and as a girl, since apparently she prefers it that way. First she wants me to beat some final boss she has a grudge against, then she takes control of my body to show me how to use my new spatial magic powers in a tutorial fight... Wait, isn't that the final boss I'm supposed to beat?! Less than in a minute into the tutorial and he's dead?! And now she says the world's my oyster. Seriously?!

An ordinary Japanese male office worker is suddenly brought to the divine realm. After being transformed into the body of a beautiful girl by the hobby of a goddess present there, I am given the mission of defeating the final boss to settle the god’s personal grudge or so I was supposed to do. Soon after my reincarnation, the goddess who possessed my body killed the final boss in an instant, and my final target disappeared in an instant? And after that, I’m told to do as I please in this world. Wait, seriously? I can really live however I want! Thus begins the isekai life of a reincarnated beautiful girl, who was originally a man, as she faithfully indulges in her desires in a world where the final boss is eliminated in just one minute.

"Come on, kill all those bandits for me already!" "No thanks. I don't wanna do any work." My name is Keima Masuda, and my hobby is spending each day doing exactly nothing... but one fateful night, I was summoned to another world where I met a blonde young girl who I named Rokuko. It seemed that fortune had favored me and I would soon be living a wonderful life free of work. But even though I'm a guy who loves sleeping more than eating, Rokuko demanded that I help her. "Save my dungeon! By the way, since you're the Dungeon Master, you'll die too if the Dungeon Core is destroyed." The dungeon only had one room, and it was already surrounded by bandits. Seriously? It's a checkmate already. I've gotta break out of this impossible situation so I can stop working and just sleep! (Source: J-Novel Club)
