In Brittania, there is an exceedingly ancient legend that shortly after the death of First Knight King Arthur due to illness, a knight entirely green appeared in the forests of Brittania.
He is always silent, almost never speaking except in very special circumstances, but his power far exceeds the imagination of mortals. He is the guardian of the Brittania Knight Kingdom and a well-known presence throughout the kingdom.
He appears amongst the forests, strolling under the shade of ancient trees, moving in the clear lake waters, appearing in waterfalls, and battling the evil creatures that desecrate the sacred ground of the Lake God.
Undoubtedly, the primary enemies of the Green Knight are the Beastmen. During the thousand-year battles, it is highly probable that the Green Knight single-handedly slaughtered tens of thousands of Beastmen, earning him the title of "Soul Slayer" among them.
