Kip. 16: Hitomiko's Barrier
Naraku attacks and fatally wounds Hitomiko, a priestess with unusually strong and powerful spiritual powers and abilities that he previously tried to kill fifteen years ago. Using the Shikon Jewel, he keeps her alive and uses his spiderwebs to control and manipulate her. He has her erect an incredibly strong and powerful barrier that traps Kagome, and begins torturing her to death. Kagome shoots the spider controlling Hitomiko, though she worries this will corrupt both Hitomiko's soul and spiritual powers. When she fires her sacred arrow, a huge light purple glowing ray of intense spiritual power shoots out and Hitomiko is able to die peacefully in Kagome's arms, after first telling Kagome that she can sense that Kagome's true spiritual powers are highly extensive, but are somehow sealed.
