E.H.

E.H. is the former leader of Heavily Ascension, a large activist group from the Outer Rim that committed many crimes against the Ark in order to receive more rights, protection, and supplies. After being set up by her former friend Crow and accidentally blowing a hole in the Ark, which led to Raptures invading, E.H. offered herself to become a Nikke in hopes of redeeming and punishing herself for all the innocent people she's hurted.
