| Hades Project Zeorymer|
Hades Project Zeorymer (冥王計画 (プロジェクト) ゼオライマー, Purojekuto Zeoraimā) is a Japanese manga by Chimi Moriwo, published under 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 was developed by AIC and Artmic.
- The OVA tones down the explicit sexual content and deviates entirely from the manga's original background.
