Feels like the first chapter had potential and this one sank that potential. Doesn't exactly feel like a revenge story if the most she bothers to think about doing is punch the guy. Girl is strong enough reach the bottom of the infinite labyrith and break out of anti magic cuffs but, get's taken down by regular guards.
Instead of wanting to murder this guy her first thought is to go after the demon king. Like, is she going to believe this guy will let her sister go if she kills the DK? Hell, I'd be flipping sides already lol.
That and she goes after a reward that grants any wish and she wants to use it to find the DK? Not to, you know, save her sister? Like, at least spare a thought to why it isn't possible.
