Log Horizon: Part 2 (Episodes 14-25) DVD

Even as Shiroe slowly learns the secrets behind the creation of the World Fraction spell, the origin of the Demi-humans, and how his own actions in the Real World have affected the world in which he now dwells, the seeds of thought he's planted in the minds of others begin to bear fruit. Game strategy and tactics may have been intended for amusement, but their origins were pulled from actual war planning and stratagems. As others begin to accept and implement those theories on their own, the existing alliances and balance of power begin to shift.

Those changes can't possibly come quickly enough, as the adventurers' preoccupations have allowed the Goblins to unite and amass a giant army. Now the Goblins are on the march, and as the Estal Lords debate their course of action, Minori makes a dangerous gamble and initiates action on her own. In the midst of this MMORPG turned real, an unassuming princess may prove to be the key to ultimate victory.
