This makes me wonder one thing seeing how I played MH. Under, Youmu player bar that shows her name and weapon are Myon, and Myon2 showing that she has 2 of them working with her. There's Myon right there right, where's the 2nd Myon?
I might be answering my own question but having that eye mean the bos monster (or monsters) have seen you so I'll just say Yukka is looking at the other Myon hidden somewhere behind Iku.
