Yu Wo (Chinese: 御我), born Chen Wenxuan (陳玟瑄), is a Taiwanese light novelist, best known for creating 1/2 Prince.

Min-Hsien Cultural Enterprise Co. Ltd. took note of Yu Wo's postings and agreed to publish her first light novel in 2004, titled 1/2 Prince.

She graduated from her university in 2006 and published Romance RPG and GOD, which were illustrated by Yuyue Boxin(玉越博幸) and Guang Shi (光矢) respectively.

Alongside 1/2 Prince, Ya Sha illustrated the novel versions of Kill No More, The Legend Of Sun Knight, and Hunting of the Shaded Guardian.
