Shinichi Sotoyama might just be the world's most average high schooler. That is, until he finds himself summoned by the Blue Demon King to a fantasy world-just like his favorite RPG games! Except this Demon King is pathetically begging at his feet, lamenting the arrival of some "heroes"...who apparently, have infinite lives and respawn over and over again?! Unlike his hysterical summoner, Shinichi coolly takes on the challenge of fending off these pesky heroes, literally shaking hands with the devil. But the demon clan is about to find out that his twisted mind is darker than the worst of them!

Who knew life without the goddess could be so peaceful...? Just kidding! With nothing to believe in, the humans are in total chaos. Trouble is around every corner-no immortal heroes and too many demons, scheming government officials, and corrupt clergy members. As if that isn't enough, Shinichi needs to deliver on his promises and tie up all the loose ends...including picking a primary love interest to conclude the final volume of the series!

After defeating the heroes, Shinichi is ready to live out his happily ever after-—until a powerful light spell blasts through the sky, marking the arrival of his newest enemy’ the Saint! Shinichi is all too eager to take down this adversary, but when he realizes she’s surrounded by holy warriors around the clock and won’t fall for his sweet nothings, he scrambles to come up with another plan. The latest rendition of his genius scheme somehow involves the daughter of the Demon King and a dirty way to make her official debut...as an idol?!

With all dirty schemes successfully deployed' Shinichi and his friends have finally gotten the church to agree to a temporary truce. Next up is...taking on the Goddess herself! Easier said than done' since they still have no leads on who she is or where she could be hiding. Their only hope is to locate a forest at the top of the Goddess's hit list' known for housing the Elven Tomb. But Shinichi will need to tread carefully: The elves protecting the sacred monument are so hostile toward humans that even the undying heroes are no match for them!

After escaping the Goddess's attacks by going deep into the Demon World, Shinichi is desperate to find a way to counterattack. But even when he scans the ancient texts to get a leg up on her, he doesn't come up with any leads. That's when he finds where the red dragon has been slumbering all this time. In this climactic volume, Shinichi realizes he needs to act now--if he wants a shot at taking the Goddess down for good!

"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!
