This is just a fan art of warhammer40000 I think,If they can make PSM, then maybe they can make female Space Marines too,Tradition seems less important than business,hahaha.

She also looks eerily like Rei from Evangelion, which... kind of fits. In the grim darkness of whatever year the newer versions of Eva are set in, there is only war. And surrealist self-loathing. But mostly war.
