Heikō Mu.

As time passed, Susanoo sought to stamp out any remnants of Heikō Mu's influence. He perceived the order Heikō had imposed on the shinobi world as a shackle, a limitation on their true potential. Any who continued to practice Heikō's techniques were summoned before Susanoo, their loyalties questioned. Those who refused to embrace Susanoo's philosophy were stripped of their powers, cast into the realm of forgotten spirits, shadows of their former selves.

The shinobi who remained quickly learned to adapt to Susanoo's doctrine. In his eyes, technique was a limitation; only raw emotion and sheer force mattered. He demanded that his followers release all restraint, to lose themselves in their rage, their passion, their fury. A new generation of shinobi rose, wielding weapons in ways that were unpredictable, attacking without hesitation or regard for form. They became extensions of Susanoo's rebellion, avatars of his philosophy of chaos.

Yet, this new style came with a price. Shinobi began to fall in battle more frequently, their lack of discipline leaving them exposed to reckless mistakes. Techniques once preserved for generations were lost, replaced by hurried, improvised tactics. The elders in the shinobi realm grew uneasy, seeing a gradual erosion of their culture, of the legacy that Heikō had built.

But Susanoo was relentless. "Discipline is a lie. Only strength matters," he declared. He drove his followers harder, pushing them to abandon any semblance of restraint. For Susanoo, the shinobi art was not about control but about surrendering to one's deepest, wildest instincts. Those who resisted were left broken, their spirits shattered under the weight of his fury.
