Spirit: Buryoku, Book 9 (Unabridged‪)‬

The seals which have long contained the majority of Buryoku's power, have been shattered, freeing the race of Demons along with them....

With a third Ancient Cavern Beast on the rise, Roy, as the Herald Clan's youngest Sage, is tasked with preventing the rise of a fourth.

Isolated from the rest of his Clan, Roy must lead a mission to the Glacial Bands, traveling through a changed Buryoku in hopes of beating both the Demons, and Beast Factions, in locating the ancient monster.

Although he has advanced to the ranks of the Sages, Roy is not invincible. It will take all he has and more, in order to succeed, and with so much on the line, the humans can no longer afford to lose.
