Cai Wenji first appeared in Dynasty Warriors 6, in mercenary mission where we have to protect/escort her (not playable), she was the doughter of Yong Cai the later Han, she is a young girl who is very beautiful and talented in playing the Harp, so she use Harp as a weapon in Sangoku Musou Game.
Repi Woo is a cosplayer who is behind this Cai Wenji Cosplay picture, although Cai Wenji is not my favorite character in Sangoku Musou game, but she has become my favorite in this Cai Wenji Cosplay picture, I really love the detail on her costume cosplay.
