Dark Secret Technique: Black Flashing Light

This technique is usually utilized as a last resort. Seishin's Kouken puppet has clings to the addressed target by surrounding itself or appearing near. By using the Dog hand seal, Kouken's chest will begin to shine brightly, initiating the detonations countdown of five seconds. Each second the seal will glow brighter until its light becomes blinding. Once the sequence is complete, the puppet will erupt in a large explosion. Powerful enough to kill anyone nearby.
