Diablo, Rem, and Shera have arrived at the Bridge of Ulug only to discover that an army of Fallen are marching towards Faltra! This should be no problem for a powerful Demon Lord like Diablo...except that Diablo is actually Takuma, a video game addict who's in way over his head. Will Diablo's stats hold up in a real-life battle?

With Diablo learning of a ritual passed down by the Dark Elves that may be able to remove the remnants of the Demon Lord's soul still slumbering within Rem's body, he tags along despite her insistence to solve her personal problems on her own (out of concern of course—it has nothing to do with the Dark Elves having gigantic breasts according to the game! R-Right...?) But a tragic injustice they had suffered in the past looms over them, making the Dark Elves hostile to the other races. Diablo steels himself for battle as bow and arrow are nocked against him: "Your petty grudges do not concern me. Obey my orders!" Meanwhile, Shera must marry a male Elf to become the Kingdom of Greenwood’s new queen!? Will the Elven Kingdom be overthrown by Diablo's great magic!? This is the seventh volume of the adventure of an earth-shakingly powerful Demon Lord (or at least someone who acts like one) taking on another world!Â

With the leaders of Holylight under his thumb, the Demon Lord decides to summon yet another member of the Sleepless Castle: Ren Miyaoji, Akira Ono’s most beloved advisor. After a brief reunion, they travel to Euritheis, where the mafia-owned company Jack of All Trades reigns with drugs, gambling, and human trafficking. The Demon Lord, the walking embodiment of hijinks, soon draws the attention of this company, and then...

The former prime minister, Noah Gibun, is revealed to be an outsider. Like Diablo, she's a player of the MMORPG who came to this world. In order to defeat the Emperor and his overwhelming power, Noah recruits Diablo and the young Demon Lord Klem into her ranks. At first, Diablo's fear of social interaction made him refuse, but eventually... “I admit it. You are the leader.” “Thank you, Diablo. I will do everything to answer the trust you’ve placed in me.” Diablo finally decides to fight in a party...?! This is the fourteenth volume of the adventures of an earth-shakingly powerful Demon Lord (or at least someone who acts like one) taking on another world!

'" Takuma was just another awkward gamer, but a twist of fate sees him summoned to another world--in the body of a demon lord! And no one''s more terrified of the prospect than Takuma himself. He may have power, but he''s in way over his head. So he decides to pretend to be the monster he looks like, and accidentally winds up with a pair of gorgeous slaves: a voluptuous elf and cat girl. It''s not what any of them wanted, but they''ll have to figure out how to work together if they want to survive! "'

Rem has been freed from the demon inside her, and Krebskulm--now called Klem--has entered the world in the form of an adorable little girl with an insatiable appetite for biscuits. But a Demon Lord still lurks within her, ready to awaken at any moment! What will happen if Klem is pushed to the breaking point? Are Diablo and his friends strong enough to stop her from destroying Faltra?

After being summoned to another world that resembled the video game Cross Reverie, Takuma Sakamoto accidentally ended up with two girls as his slaves: the Pantherian, Rem, and the Elf, Shera. Takuma, under the guise of his screenname Diablo, came to this world a powerful Sorcerer, just like his avatar in the game. Along with the two girls and Emile, a devilishly handsome Warrior, they managed to protect the town of Faltra from the looming threat of invasion by the malevolent Fallen. But that peace they brought upon the town did not last long. The Kingdom of Greenwood, a country of Elves, makes a troubling demand: if their princess isn't returned to her rightful home within the time allotted, then the Kingdom will declare war on Faltra-- And it's up to Diablo and the others to prevent a war with the Elves! So begins the second volume of an adventure with an earth-shakingly powerful Demon Lord (or at least someone who acts like one) taking on another world!
