Hi. I'm currently watching the anime DVD's and am at the Hoshigakure Arc. Does anyone know anything about why some character's eyes glow the same colour as the chakra of the star randomly? I noticed this on Akahoshi and Sumaru primarily and I just assumed it to be the chakra of the star controlling the user's body, but I'm not so sure. Anyone got opinions on this?
