hades_project_zeorymer_omega
A sequel to the original Hades Project Zeorymer manga, it ran from 2008 to 2017. Illustrated by Watari Yuu (watari65U).
Unlike its predecessor, Zeorymer Omega is not an R-18 manga, and it's story is heavily based on a proposed Sunrise (company) adaptation of the original manga that ultimately never came to be.
