Otokonoko Zuma (Japanese: おとこのこ妻, "My Wife is a Man") is a slice-of-life romantic comedy manga series written and drawn by Crystal na Yousuke [ja].

Shogakukan serialized it through its webcomic platform Sunday Webry [ja] from July 15, 2016, to January 31, 2020, and released it across three collected tankōbon volumes between 2017 and 2020.

Otokonoko Zuma is a romantic comedy manga following a loving married couple: the soft-spoken and feminine Yuki, and the honest and quirky Kou.

[5] Otokonoko Zuma was critically well received,[3][10] but despite this, the collected volumes only saw a very limited print run; Crystal na Yousuke described it as "unlikely" that readers would find copies in book stores and recommended reading the e-book versions.

Although the series does not discuss LGBT issues much, they did not think it felt missing, and liked seeing Yuki and Kou being happy together and their families accepting them, describing it as a good portrayal of a loving marriage.
