The Ryukyu Islands, a center of diverse cultures, have absorbed martial arts techniques from various nations, giving birth to the distinctive and deadly Okinawan martial arts. This fusion, a product of centuries of trade and cultural exchange, has created a unique style forbidden for use except in self-defense. However, the question arises as to whether this tradition still holds relevance in Japan's current occupation of the island, especially in light of the Meiji Restoration. Ironically, Master Kyoshi of the prestigious Kyoshi School of Okinawan Martial Arts stands accused of using this sacred technique for murder. Is there a motive behind his actions, or could someone else from his school, who learned the deadly method of ending someone's life from the same institution, be involved?
