In the heart of Japan in a land called Shōrinkyō, nine legendary warriors known as the Hashira-Rengoku Kyōjurō, Tomioka Giyu, Kochō Kanae, Shinazugawa Sanemi, Iguro Obanai, Himejima Gyomei, Tokito Muichirō, Kanroji Mitsuri, and Uzui Tengen-stand as the eternal guardians of their homeland. For centuries, they have protected their people from threats both mortal and supernatural, bound by duty, strength, and unshakable resolve. Far across the seas lies Setsugenkyō, a hidden kingdom of eternal ice and snow. Ruled by the enigmatic and powerful Queen Shirayuki, the frozen empire harbors dreams of expansion beyond its borders. At her side is her most trusted general and daughter, Shinobu, known as Chō-no-Kami, the Butterfly Goddess of War. Trained from her youth and forged in countless battles, Shinobu commands loyalty and fear alike, her elegance masking a steel-like will. When Queen Shirayuki sets her sights on Shōrinkyō, her icy armies sweep across the land, seizing territory with ruthless precision. For the first time in generations, the Hashira face not demons but a kingdom of men and magic determined to erase their sovereignty. Outnumbered but unbroken, they vow to reclaim their homeland at any cost. Yet fate twists unexpectedly when Tomioka Giyu crosses paths with Chō-no-Kami. Beneath her cold exterior, he senses a hidden light, a fragment of goodness that the queen's conquest has long suppressed. As battle lines are drawn, Shinobu herself begins to question the truth of her identity, the path she has walked, and the queen she serves. Now, Japan's survival rests not only on the might of the Hashira but also on whether Chō-no-Kami will remain a weapon of the Ice Queen, or awaken as the key to freedom.
