As the battle against the orc Jumbo and his group Forgan descends into utter chaos, Haruhiro and the party face a crisis unlike any before: Ranta has betrayed them to join Forgan.

From there, they are split up again and fight an intense retreating battle. Without knowing who among the other party members is safe, Haruhiro and his comrades realize anew what the other members of the group mean to them. Having only realized what they had now that it may be gone, will Haruhiro and the others really lose it, or...?

When they encounter an enemy known as "solitude" in the misty Thousand Valley, this tale of adventure that crawled out of the ashes will begin to weave a new act.
