Like in a movie.
Running against time.
Rubra and Nemesis didn't actually want to save the world.
They were already finding difficulties dealing with the dangerous mix of enviousness and sexual tension the scene emitted.
*If I react thus and so, in what way will the maids manage restraining themselves? *
The self-interest hidden.
Only Rubra's actions hinted at her genuine purpose.
Even now, what gave her energy wasn't altruism but territorialism.
Her instinct could only hardly accept Eve.
If the unmentionable act with the maids had indeed taken place, she wouldn't have held herself accountable for her following actions.
What was buried inside her was clearly shown off by Nemesis.
In fact, the closer she got, the more her fighting aura increased.
Finally, as in every movie worth its name... they were late.
