Spring, Harima Province, 1598. A swordsman trains in seclusion, sharpening his blade for the battles ahead. But one question lingers… "What does it truly mean to walk one’s own path?" Seeking answers, he is given an old book—Kokutenma. Within its pages, the past awakens. A swordsman without a master. A world shaped by war, spirits, and unseen forces. A journey told not as history, for history has tried to erase him—but as if it unfolds in real time. Each battle, each revelation, pulls him deeper. But as he nears the final page, something feels wrong. The story should have ended yet the ink refuses to set. And some paths, once taken, do not end.
