Where?
Aina stood in silence for a while, but to the surprise of many, her expression didn't change at all, nor did she erupt into a burst of ash. She didn't seem to have ingested any poison at all. Even if she was immune, she should have at least felt some pain, but she didn't react like that in the slightest.
There were certain Ability Indexes that could allow one to be immune to certain poisons, but everything had their limits. They couldn't fathom why it was that Aina would be so confident, even those immune to poison wouldn't necessarily go out of their way to consume it, let alone so much of it in a single sitting.
Of course, how could these people know that Aina was used to far more pain than this? As a child, she would probably be thankful if she could spend a day with this sort of pain. It wasn't until she consumed Leonel's Cleansing Waters for the first time that she reached a state where that pain instead became itchiness, which was far easier for her to handle.
