so she is old but not nearly old enough to have been around when it was supposedly common unless stuff hidden from the general population and there was some sect of humans treating each other horribly, even if she was an isekai'd person too it'd be odd that she experienced that AFTER if all humans are mostly at peace. especially as what looked to be a little child. her background grows more curious. plus i agree why would she make an antidote if she doesnt want humans to exist. curious... very curious..
Yeah, I don't care what sort of tragic bullshit background they give Circe, she's an irredeemable piece of shit. Buhu, I got slightly sad. Genocide time.
