Shadow Senbon

is a simple technique using senbon, the user throws senbon with bells attached and senbon without bells at the same time. The intention is that the opponent will only react to the sound of the bells and won't notice the silent ones, getting hit by these. This technique focuses on how the brain instinctively works: reacting to the sound, the brain "forgets" about the information provided by the other senses. However, it is very easy to evade the attack if the opponent recognises the trick and simply focuses on how many senbon were actually thrown.

Kin Tsuchi makes a more advanced use of this technique by attaching strings to the thrown bells and ringing them from unexpected positions, distracting her opponent long enough for her to attack.
