Yin-Yang Release: Blackbird

Yin-Yang Release: Blackbird is one of the many ways Kisui demonstrates his mastery over the powers of Yin and Yang. By separating his energy into the halves of Yin and Yang, he splits himself into two entities. As his Yin half stands still, his Yang half stays unseeable by the human eye. As his Yang half charges, it creates a buildup of massive amounts of energy. Using this energy, it increases its speed to incredible levels. Once it makes its pass away from Kisui's target, a shockwave forms from the path his Yang half took. This shockwave is seen seconds after its activation by the human eye as a wave of black. What follows behind it is a deafening roar that renders his target temporarily deafened. The shockwave can deliver tremendous internal damage if the body is unable to handle the forces behind it. Only a select few are capable of withstanding the shockwave's forces, which are strong enough to pull a tree from its roots. Once the execution is complete, Kisui's Yin and Yang forms reunite.
