Yui Nakamura

Yui is a 21 year old woman who uh..Has "special" feelings for her teammate Erin. Since her father is the lord of the "Red side", She didn't have many friends as a kid. But when she snuck behind the border she met Erin. It was love at first sight...Well for her, Not at all for Erin. Is she a Human or a Hellrex? Nobody knows!
