Metal Release: Bullet Curtain

Creating metal bullets, the user propels thousands of metal rounds at extreme speed to pierce targets. Every bullet can be controlled independently and travel at such extreme high speeds that they leave wielders unable to react in time. Due to the user's ability to readily make metal bullets, there is no practical limit to how long they can make use of this technique.
