Yun Kōga

Risa Kimura (木村 理沙, Kimura Risa, born July 9, 1965), better known by her

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.

During her years in middle school, she had been a fan of Masami Kurumada's manga series Ring ni Kakero, Fūma no Kojirō, Saint Seiya (all serialized in Weekly Shōnen Jump) and B't X (serialized in Monthly Shōnen Ace), sending Kurumada numerous fan letters asking to meet him, after which Kurumada finally agreed, inviting her to his workplace.

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.
