Naruto Thread (Spoilers For Sure)

Again, there's no horn in that image, IDK why you link me to it as if I hadn't already seen it and zoomed it. http://img.mangastream.com/cdn/manga/49/2383/06-07.png

If anything, that's a branch tip breaking through the scroll before changing pages.

It's the horn, look closer, you are seeing the right side of it, the left side (the bigger horn) is the one piercing the scroll, so it's not visible, also it clearly looks like if something is piercing in, not getting out.
