I started reading this manga because I was on a binge of the demon's daughter type of stories and I can say this definitely pass the Pareto Principle.
First of all, the pace is good. The first season just ended and I can say that in no moment I thought the story was dragging. On the contrary, there are so many cool tidbits about the culture of the demon world that I wish things could have been slower so we could appreciate them better. It also wasn't rushed, everything happened just right.
On the world building, I love the demon's culture. There are many fun tropes and themes that are executed in a fun way that comics rarely are able to. For example, it's a matriarchal society, but every gender has their value in society, it's more like a penguin society where the male raises the progeny and the females are biologically stronger but everyone gets alone and everyone is gorgeous.
Which leads me to the art, which is gorgeous. There is, of course, the weird ass horses that Korean artists really don't know how to draw ever but aside from that everything is beautiful. The characters design are also very nice, and the MC animal companion in his mini form is just adorable.
The story itself is adorable, and there are many elements that points to it not being always like this in the future -- there is a war brewing, there is a dangerous opposing faction, there is a deadly contest for the MC generation approaching soon, and so on. And yet, the authors know how to put them in a way that they make the cute MC learn about them, sometimes participate in them, but still important and maintain a certain lightheartedness.
The characters are interesting. The MC is a charming child (no transmigrator, thankfully), her family consists of her father and brother. Her relationship with her brother is specially funny and I love their moments. The season ends just as she is expanding her horizons and meeting the demon society, and the characters there also look promising. Specially the ML, who, in a very cool switch, actually has the power of seduction.
I wait eagerly for the next season. And if I can give a tip is to not read the fans translation because they exaggerated her lisp so much it became unbearable.
