It wasn't her or her mother's fault. It was the fault of those beasts that were unable to control their greed and lust.
The desire to get revenge grew even stronger inside her, as it made her killing intent spread in the surroundings around her.
Then she was suddenly reminded of something. Before she died she could clearly feel that there was a strange and dangerous substance in the air.
In fact, seeing the signs of the soldiers, and Masters dying around her, she felt like those signs were the same as the signs that her mother had shown until now, just stronger, and quicker.
That wasn't the most important point though, the most important point was that the naked woman, which was that hooded Rank 4 Master, was actually poisoned as well.
Yet she was perfectly fine right now, restricted by Roy!
That would have been impossible if Roy hadn't actually cured her poison for her. Which meant that Roy had the antidote to the poison.
