Wait, yeah. Talking to a goddess is definitely not normal. I didn't expect the manga to go over this. Usually, something like this in a story, you're just supposed to ignore it.
I do understand your point but the thief didn't get the adrenaline and endorphin you get when you get stabbed. Also, we don't know just how much pain Aria has gone through. Not only training with Feld, but any other training after that + injuries.
Well, damn. I don't usually read those wall's of text in manga's but.... That had quite a bit of backstory. Now I feel for her dead parents more than I used to.
Feel like the author could've made the first chapter better, but all stories need somesort of starting pojnt, even if it is boring. Like, why would the "villainess" accept so quickly without question?
