In the fourth form of the ura set the kamayari blocks a thrust to his uramen to his left side then forces the suyari first into gedan then back into jōdan on his ura side before sliding his left sickle towards the suyari's left hand when the suyari attempts to thrust to his uramen again.
The suyari starts in gedan while the kamayari begins in jōdan.
On the third step the suyari thrusts to the uramen of the kamayari who blocks this thrust with the shaft of his spear to his left side
Now the kamayari steps forward with his right foot bringing his right hand up at the same time. This lets the tip of his spear describe a counter-clockwise semicircle that ends in gedan (the sickles are in a vertical position now) forcing the suyari who retreats one step into gedan as well.
Making another step forward the kamayari continues his counter-clockwise circle until the spears are in jōdan on his left side again while the suyari retreats one more step.
Sensing his last chance the suyari now attempts another thrusts towards the kamayari's uramen which the kamayari counters with surikomi, sliding his left sickle towards the left hand of the suyari.
Both now disengage and return to their starting positions.
