@Soul Reaper K. Could be what he's saying. @Shakhmoot-senpai I pointed out here on chapter 510, page 11 (when Hagoromo was using the COAT) that there was some what of an eye with six tomoe behind Hagoromo. In the anime episode of that chapter (although the anime is not indicative of the manga coloring), in episode 253, that eye behind Hagoromo was purple with six tomoe like we see now.
