Yun Kōga

In 2007, she contributed the character designs to the Sunrise anime series, Mobile Suit Gundam 00.

When asked about her penname in an interview in the September 2006 issue of Puff, she responded that she had originally thought of making it Jun Kōga, but subsequently changed it to Yun Kōga.

Among her noted works is Loveless, which has been serialized in Monthly Comic Zero Sum since 2002 and is ongoing, as well as her work Tenshichō (天使庁). She has also worked as an illustrator on the noted literary magazine Faust.

She debuted in a commercial magazine with the original work Metal Heart (serialized in Kobunsha's Comic VAL from November 1986). After her debut, she continued to contribute on numerous dōjin works. However, the later disbanding of a dōjin circle, Yajō Teikoku, she had founded with Maki Chikura, led to her taking numerous breaks from her commercial works. Due to this, there were incomplete works penned by her during this period.
