Loner Life in Another World (Light Novel) Vol. 7

CLASH OF THE DUNGEON EMPRESSES High school loner Haruka has been busy since he and his entire class were summoned to a fantasy world. Having driven out the insurrection-causing prince, now Haruka must face the Frontier Reclamation Army—tens of thousands of soldiers—to protect the frontier. Alone. And that army isn’t the Theocracy’s only weapon. They’re causing artificial dungeon monster breakouts to terrorize the lands, plus the final ace up their sleeve… Something powerful enough to give the former dungeon boss, Angelica, a run for her money!
Series Overview: When sarcastic loner Haruka gets transported with his class to another world, he’s not wild about adventuring, but he wouldn’t mind having some cool powers. Unfortunately, he’s last in line when the magic cheat skills get divvied up, so by the time it’s Haruka’s turn, there are no good choices left. Now Haruka will have to take on this fantasy world the hard way–on his own, with a hodgepodge of bizarre skills! When infighting and chaos break out among his classmates, can this loner come to the rescue?
