Jianyu (ヤンユー Yan'yū?, October) is a member of the Dolls. Originally from China, Jianyu and her twin sister Xiayu were kidnapped and brainwashed by Shadaloo to be trained as an assassin working for M. Bison. Her name is derived from the archaic Chinese word for October, Yáng yuè (陽月, lit. Yang Month).[citation needed]
