I often find light novel translations to be a little awkward, there is something about the sentence structure that always feel a little clunky to me. Something I didn't experience much with this translation. (I might need to read more J-Novel Club books tbh)
I found this story to be both lighthearted and funny. It features a typical theme of finding oneself reincarnated and taking over the body of someone else. In this case, a little sick girl who has just died. The new inhabitant is a battle crazy blood enthusiast whose only desire in life is finding someone stronger than them and dying in battle. Something that is funny when the person is a frail little 4 year old girl who nobody takes seriously. Who also happen to be ridiculous powerful, as in her past life she was well trained in using something called Chi. A force that the locals seem to be unaware of. (Tho magic is also a thing, tho one that is mentioned but not shown)
What follows is a story of how she keeps looking for people stronger than her to potentially fight and her plans being foiled by her nanny/maid/bodyguard and her dutiful attempts to be a good daughter and help her family regain the fortune spent attempting to cure her.
Something she does by getting involved with something called Magi-vision which is basically a fantasy version of TV. (Something her family invested heavily in to find a cure for her )
That was an interesting thing that I haven't really encountered much in other books. Much less in an fantasy setting. If one have no knowledge of the concept, what thoughts and reactions one has to it. And the ideas on how to make it popular and more widespread.
I liked book 2 a little more than book 1. Book 1 has a much smaller character pool than the second, the second seeing Nia start school in the capital. Which means a much bigger character pool and more humorous encounters.
They're both short books, coming in around 250 pages.
An additional note, is that I was extremely happy with the lack of sexualization. A common thing you often encounter in the manga/anime sphere, and thus light novels. So I feel comfortable recommending the book even to people outside of that culture.
