The invasion of Zircon Tower heats up! Faced with the Fallen's overwhelming military might, the defenders of the city, led by Laminitus, seem to be cornered...until Diablo, his crew, and his powerful lightning magic appear! Decked out in new gear from his dungeon, the Demon Lord is ready for his comeback!

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!

SWEPT AWAY In order to cure the Marked Death Disease, Diablo must raid his own dungeon to retrieve a healing talisman from his treasure trove. But when lowly adventurer Horn is carried off by a raging underground river, Diablo must leap in after to save him! Meanwhile, Rem, Shera, and Lumachina continue on as planned, only to encounter a Black Dragon!

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?

'" 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! "'

CHAOS IN THE CATHEDRAL With Zircon Tower safe, Diablo and his crew turn their attention to the corrupt Cardinal Council. But danger lurks beyond the church walls, as Diablo realizes once again that not even powerful magic and enchanted gear can level up his ability to talk to girls.

After the Gryps, it's time for the Lindwurm tournament! Ayato has been training for the competition in hopes of saving Haruka, who has been taken as a hostage...but what about his promise with Julis?

Diablo 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?!

Satou and his companions have arrived in Gururian City, and all around them, mock battles are a common sight in preparation for the upcoming martial arts tournament. Meanwhile, the Wings of Freedom, a demon lord–worshiping cult, is giving speeches in the streets, and sure enough, a horde of demons soon emerges from within the city! Amid the chaos, Satou and friends rush to the scene, only to find an unexpected guest...
