Yellow Secret Technique: Poison Water River

Utilizing Mamushi, Kōsa causes the serpent puppet to release a large cloud of a liquid yellow poison from the fangs of the puppet, in a similar style to a spitting cobra. Unlike snake venom however, this poison can be absorbed through the skin, but is much more effective if it can get in the eyes, mouth or on any cuts.

The poison will not cause any symptoms at first, but after an hour (or shorter if the afflicted has been fighting) the person afflicted by the poison will experience nausea, extreme fatigue and finally severe pain in the lungs, with each breath causing agony. The person afflicted by the poison will die within two days without an antidote.

Trivia

 * The "Yellow Secret" (黄秘技, Kihigi) name comes from the color of the poison used.
