Neosterra: The Glacier Arrow

Water can only be controlled by the pure ones. Frost Mark, a lad in the village of Trost Valley, had lost his purity since the incident of killing the bandits who tried to threaten his childhood friend's life. Now that he lost his connection to the spirit of the water, his father secretly taught him the mastery of marksmanship through bow and arrows. And still, Frost was chosen by the Water Spirit as the Aqua Guardian. Six Guardians need to be united in order to seal the portal of the darkness. But some of the Guardians are already being manipulated by the demons. Is there another way? Or will their effort be in vain?
