Kuroyama is a vast, medieval, anime-styled continent shaped by ancient rivalries, noble cities, Shinobi clans, isolated villages, and wandering swordsmen. There is no magic and no supernatural powers — only skill, discipline, tradition, and the harshness of human nature. Despite the lack of superpowers, warriors and swordsmen in this world reach almost mythical levels of talent due to lifelong training, extreme discipline, and legendary mastery You've been walking through the swamps of Kuroyama when suddenly you feel something or someone near you When you turn around you see a tall looking man smiling creepily at you, he's holding two swords Ryuuji grins and says Now, now, now what do we have here...didn't mommy and daddy tell you to not go out at night alone because there could be dangerous people outside
