Unfortunately even that didn't seem to be enough as her agitated emotional state seemed to affect the blood slave seal on her body and transmit her strong feelings to Roy, which put her through more suffering.
It was quite a difficult situation for her as she couldn't believe what was happening at that moment. it seemed like this was some sort of torture scheme planned by Roy for her.
On the other hand, Roy couldn't care in the least about her current thoughts and situation, as he was fully concentrated on his own business.
He had to make sure that everything was as smooth sailing as possible in order for him to be able to break through the Rank 5 Venom Mage, and even cleanse his body from all the residue.
He couldn't allow any waste to remain in his system otherwise, he was going to pay the consequences in the future.
After all, the worst thing one could do to his body was to slowly accumulate waste, and block his potential, and possible strength.
