Why is Erza able to feel pain during Kyouka's fight? Don't read the question below if you are not up-to-date to the Fairy Tail manga. It may contain spoilers


In the chapter 399-400 from Fairy Tail manga, Erza is fighting Kyouka to stop faces's activation.

During this fight, Kyouka used her curse to increase Erza's sensitivity to pain.



After this curse, she used another one to remove all Erza's five senses. But Erza continued to fight.




One of the five senses is tactile perception. Without it, she should not be able to feel anything, including pain. Shouldn't it make Kyouka's first curse useless?

But somehow Erza continued feeling a lot of pain and suffering a lot.



How can she feel this amplified pain since all her senses were stolen?
According to Wikipedia, pain isn't one of the traditional senses. It's marked under non-traditional senses.

I think that's the reason pain is NOT stolen together with tactile perception (well, I thought, before I looked deeper, pain is connected to the touch sense, but it seems not).

Traditional senses:


Sight
Hearing
Taste
Smell
Touch


These are 5 base senses (for more info, view this article). As you can see, pain is not listed. But there are others like:


Balance and acceleration
Temperature
Kinesthetic sense
Pain
Other internal senses


As you write, 


  she can curse to increase Erza's sensitivity to pain


but then 


  she remove all 5 senses from her in other curse.


Pain is not a base sense.
