Index compared the image in front of her with the knowledge in her brain and made this conclusion. Right now, besides ‘The Kinugyokutoshū’ (The Moon and The Rabbit), ‘The Book of Creation’, and the ‘Book of the Law’, the library in Index’s brain has stockpiled a few shounen manga.
In fact, the girl who's keeping the 103,000 grimoires in her head is already used to this kind of crisis. So her body has some sort of resistance. For example, she can adjust her breathing to let her enter a status of anemia to decrease the pain.
But the effect is still limited.
If her blood flow is sealed up and she sees her hands and feet start to rot, she doesn't believe that she can maintain her sanity. Of course, nobody has this belief.
Although Index has another defence system that even she didn't know of, unfortunately, this system was destroyed by the boy's right hand.
People like Index, who never even got any combat training, they can't even hurt others.
