Yasashii Ryuu no Koroshikata

In a world where the realms of humans and mythical beasts exist in a state of perpetual conflict, two ancient clans have maintained a fragile peace for centuries. This uneasy truce was forged through a solemn promise made by the leader of the mythical beasts, who gifted his sword to the human queen he loved, swearing to protect her and her lineage from harm. The pact ensured that if the queen or her descendants ever faced danger, the king and his descendants would come to their aid without hesitation. This fragile balance is about to be shattered as the third great war between humans and mythical beasts looms on the horizon. Amidst this tumultuous backdrop, a skilled swordsman with ties to the Holy Queen has a fateful encounter with the reclusive king of the mythical beasts. This chance meeting sets in motion a chain of events that will test the strength of their alliance and determine the fate of the fragile peace that has held for so long.
