Made it to another lock in Keitaro Miura's route in 13 Sentinels. So Yuki is Minami's mother in "reality." I guess it makes sense why the clone Yuki always says that Minami is the only person she cares about now. Also, I suppose Universal Control just removes all the incompatible people from a sector once the kaiju start invading, which is why we never find any other people in post-invasion sectors. Also, Gouto put Morimura's memories in the little girl Chihiro so she could carry out Operation Aegis, so he at least appears to be on board with the plan.
