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?

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!

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...

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!

OVERPOWERED OVERLORD! 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...

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?

Diablo 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!
