Lucifer placed the beast core he received after killing the Black Stone Beast on the lips of Alicia, who had her eyes closed.
After placing the core in her lips, he stood up in search of water which was also needed.
Unfortunately, there was no source of water nearby, and he wasn't carrying any.
Without water, he couldn't finish what he wanted to do. He couldn't finish the process of detoxification.
For that, he needed some water or liquid that could touch the beast core before falling on Alicia's lips.
He observed his surroundings, trying to find something he could use, but except stones, there was nothing.
"Is there no way to heal her?" he wondered as he walked back to Alicia, sitting near her. "It would really be unfortunate if she dies like this."
"Do I really have to use that?" he muttered, glancing at the lips of Alicia where the beast core was placed.
"There you are!"
