Oh lol, I can see the effort of the author trying to justify this 'relationship' giving us the ages of the characters, and even making her formally way older than him so maybe we can think this is ok but eh, I guess I'm trying to force myself to think it's plausible rather than focus my mind in the weirdness of the difference of their looks (especially in the colored cover in this chapter, where she basically looks like a small child).
I understand that lolis exist in real life, but I wish authors would work on this in a way where the characters wouldn't look like an adult and a kid (especially in romantic couples) since u know, that's ped*philia and pedos are not some kind of fantasy, they exist and they're one of the most disgusting creatures in the world, so yeah. I'm not saying "Japanese artists, pls stop creating lolis", I'm just saying "Japanese artists pls, if you're gonna use lolis pls don't put them in situations that can be interpreted as victims of ped*philia, pls don't make the MLs look way older than them, pls don't make it weird in that aspect". U know, ain't that hard to be aware of things that matter to the world, or to be accountable of what your work can communicate (I mean, every creator must be aware of it, and if it's truly not their intention to share that kind of signals, then there's no need to do it in that way) and try to make them as less as possible.
Letting that aside, this 1st chapter is still creepy, mainly because if she hasn't done anything worthy of a Demon Queen, it means she probably hasn't killed humans or blabla, so this weird dude is trespassing a little girl's private property (lol), and then he and his friends kill every one of her family members/allies/people of her household with the intent of killing her, regardless of her true actions just because of her position and then they're planning to go drinking and have some fun. That's hella crazy and it reminds me of the 'Clockwork orange' movie. And if that wasn't enough, that weirdo saw her face and kidnapped her to have her trapped in his house, where he could see her thighs as much as he can because yeah, that's what a true hero (or sexual harasser) would do. Is that ok? I agree with one of the comments below, someone needs to call the police. :l
I'll try to give another chance to the story but I hope it won't get weird. Tnks for sharing.
