Hades Project Zeorymer, known in Japan as Project Zeorymer , is a Japanese manga series by Yoshiki Takaya, written under the pen name Chimi Moriwo, and published in the adult manga magazine Lemon People from October 1983 to November 1984. A three-part finale was serialized in Monthly Comic Ryū in 2007. A four-episode OVA adaptation by AIC tones down the explicit sexual content and deviates entirely from the manga storyline and setting.
