In the twelfth form of the ura set the kamayari first knocks the suyari upwards a little before performing surikomi.
Both spears begin in gedan.
On the third step forward the suyari thrusts towards the maemen of the kamayari who answers with a light hikiotoshi not knocking down the suyari.
Immediately the suyari now thrusts to the kamayari's uradō while making a backward step with ayumiashi. The kamayari makes one forward step also with ayumiashi beating the suyari lightly upwards with the shaft of his spear (which he had opend to his left side turning it 180 degrees lengthwise) before performing surikomi with his right sickle with another step forward whilst the suyari makes another step backward.
Both then disengage and return onto their starting positions.
