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?

For the first time since waking up in his favorite MMO, Diablo is up against an opponent that's actually as strong as he is! Galford is a mighty warrior and the governor of Faltra, but instead of keeping the peace, he's been trying to start a war with the elf kingdom! If Diablo can't defeat Galford in battle, then the whole world's in trouble!

After being summoned to another world similar to the game he used to play, Diablo lives a tumultuous life in this new world after he finds himself the unwitting master of Rem the Pantherian and Shera the Elf; and now, even the Demon Lord-turned-young-girl Klem obeys him! One day, Diablo ends up rescuing a holy woman who was being pursued by a Paladin, and she turns out to be the most important person in the Church. Befriending her, Diablo and the others act as her escorts until they reach Zircon Tower deep in the Demon Lord's territory. After arriving in a new town, more difficulties arise, ultimately culminating in the appearance of a gargantuan monster attacking them! Is the self-proclaimed Demon Lord becoming a guardian deity for a follower of the Gods!? This is the fourth volume of the adventure 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! "'

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!

With the threat of Krebskulm's resurrection safely suppressed (for now, at least), Diablo and his companions hope to enjoy a little peace and quiet. But a mysterious young woman has appeared in the forest outside Faltra, on the run from another Paladin. When Diablo stumbles upon her, it opens the door to a new adventure!

Ever since Takuma woke up in the world of his favorite fantasy MMO, he's had to play the part of the big bad demon lord. Now, with busty Elf Shera and cute cat-girl Rem by his side, Takuma is ready to go on his very first quest! But when their quest turns out to be a trap, the trio might be in over their heads...
