Spoiler:

But aren't characters in L4 or L5 only able to hear Hanyuu? Takano was able to see her as well. Furthermore, that scene took place years before the the Great Hinamizawa Disaster, so if Takano was in such an advanced state of the Hinamizawa syndrome you'd expect her to have clawed her throat out years ago. Besides, Hanyuu took a physical action by throwing the coin back at her, so my guess it that Hanyuu got so angry at Takano that she managed to make herself to appear before her.
