Hichu (Jugular notch – Larynx)
Causes loss of consciousness due to blocking of the windpipe. A hard strike to this point causes the Tracheal cartilage to be crushed and death by asphyxiation.
Suigetsu (Solar Plexus)
The heart is also located in this area, with the liver and stomach below. As there is no protection from the ribs, a strike will shock the heart, diaphragm, and nerves between the ribs, causing pressure on the heart, difficulty breathing and intense pain in the stomach wall. Severe blows may cause bleeding in the stomach, irregular heartbeat, unconsciousness and possible death.
Wanshun (Back of the Upper Arm)
Causes trauma to the nerves and blood vessels, numbing the arm, and producing pain in the chest and neck with associated loss of motor function. Severe strikes may cause a heart attack, especially if the person has a bad heart or if they are using narcotics. Astarl uses this one to immobilise a man who gets a little too friendly in a situation where she needs to be discreet.
Kusagakure (Lateral Planter nerve)
Causes trauma to the nerve and surrounding nerves, leading to the loss of motor function. Severe blows may cause fracture or dislocation of these bones, producing severe pain and partial paralysis of the lower leg. Astarl uses this one in a fight when she finds herself on the ground and her opponent’s foot is the only thing within reach.
Kokotsu (Deep Peroneal nerve)
When struck or raked it causes a sharp pain, weakening the whole leg and paralysing the muscles. A more severe blow to the shin will cause a fracture to the tibia. Astarl attempts this manoeuvre a few times – once successfully breaking her opponent’s leg.
Fatal striking to this point will create shock waves in the cerebrospinal fluid surrounding the brain, quite distant from the point of contact, upsetting balance, coordination and decreasing reaction time.
There are plenty more, in fact so many I couldn’t possibly have used them all in the one book, but since there are another five books planned with Astarl, I should have plenty of opportunities to try the rest out.
