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!

THE DEMON LORD AND THE DARK ELVESDiablo and his companions arrive at a Dark Elf village, searching for a magic ritual that can extract the soul of the Demon Lord sealed inside of Rem. They succeed in gaining an audience with the village's top-heavy chief, Rafflesia, but there's a problem. Shera is elven royalty, and a deep grudge persists between the elves and dark elves. If Diablo's party is to win Rafflesia's favor, they'll have to fulfill some very tough conditions!

THE DEMON LORD AND THE ELVEN THRONEDiablo and company rush to the Greenwood Kingdom, where Shera's father, the king of the elves, has recently passed away. Once they arrive, Shera swiftly becomes the center of attention. Whoever marries her will end up as the next ruler of the kingdom! Unfortunately, Shera's mother has already decided on her preferred fiancé, and he's a frightening ogre of an elf. Just what fate is waiting for the princess of the elves...and is Diablo going to stand for it?!

A DANCE OF DEMONSDiablo and his companions have saved the Kingdom of Greenwood from the Demon Lord Kardia, long sealed beneath the elven wood. But at the very moment they claim victory, two more overwhelmingly powerful demons appear! To prepare for war with humanity, these demons plan to sacrifice Kardia to their master, the Overlord Modinaram, so as to bring him to a truly terrifying height of power. Diablo is the only thing standing against them...and is it possible he might wind up being appointed king of the elves, despite being a demon himself?

BOW TO YOUR SENSEI!With the Demon Overlord Modinaram threatening all humanity, Diablo decides it’s time to raise his level as a fighter, ASAP. After a quick trip to Faltra City to gather information, he sets out for the northern mountains of the Demon Lord’s Domain. His plan is to find the swordmaster Graham, study under him, and learn his peerless swordsmanship. Instead, he winds up discovering a cute dwarf girl named Sasara took over the mantle of Swordmaster just half a year earlier! It seems like becoming her disciple won’t be easy, either…

EYE OF THE TIGERDetermined to raise his fighter class levels, Diablo overcomes the difficult trials set by the (supposed) Swordmaster Sasara. He becomes her disciple in no time, and is all set to undergo the final–but most grueling–challenge. Yet before the ultimate trial can even begin, the Demon Overlord Modinaram begins the invasion of Faltra, and our beleaguered party is attacked by...an Evil Ape?

AT MY SIGNAL, UNLEASH HELL!The war of the Fallen against the mortal Races begins. Eulerex, the Supreme Commander of the Demon Lord Forces heads one side, while the other is led by Governor Galford of Faltra. The Races put up a gallant opposition, but a Demon Overlord Cannon greatly reduces their numbers and the walls of the city begin to crumble. Klem and Edelgard come running to the rescue, but with the appearance of Demon Overlord Modinaram and the Fallen girl Ryoka, will they be able to turn the tide of battle?

"I WILL ANNIHILATE YOU!"The Demon Overlord Modinaram has awakened! The people of Faltra cower and fall into despair when even the combined might of the city’s defenders fails to best Modinaram, who has absorbed the powers of multiple Demon Lords. Diablo races to the scene--will he be able to bring an end to the war between the Fallen and the mortal races?

DON'T LET YOUR GUARD DOWN YET!The war with the mortal races comes to an end, thanks to the valiant efforts of Diablo, the Demon Lord from another world. Peace finally reigns...for a short while! The Demon Overlord Modinaram is still very much alive and kicking, and the evil one has found a new living body to possess. Even worse, it's someone very close to Diablo's heart...!

DOUBLE TROUBLEThe war is over, and peace finally reigns--but an even greater conflict looms on the horizon. Our mighty Demon Lord faces an entirely new kind of trouble after he gives one ring to Rem and another to Shera. The rings are a matching pair...wedding rings, to be precise. Rem and Shera have just been wed to each other without their knowledge! Diablo must now scramble to untangle this mess before the ladies discover the truth!
