Twelve Kingdoms


Links are NOT allowed. Format your description nicely so people can easily read them. Please use proper spacing and paragraphs.

For high-schooler Yoko Nakajima, life has been fairly ordinary–that is until Keiki, a young man with golden hair, tells Yoko they must return to their kingdom. Once confronted by this mysterious being and whisked away to an unearthly realm, Yoko is left with only a magical sword; a gem; and a million questions about her destiny, the world she’s trapped in, and the world she desperately wants to return to.

And the "Best world building/design" award on "The Asian fantasy novel awards" goes to... The Twelve Kingdoms!!!! Yeah its that good! Plus there is so much more left unsaid... So much to build on top!

Plus each book is not directly a followup on the previous one! Most of the time they are different plots on the same universe!

Great story!

I had kept an eye on Juuni kokuki anime for a long time and now that I binge watched it, I got hooked to know what happens next and since anime was obviously cut mid series (dunno why) I eyeballed first 4 volumes that anime story focused upon and now volume 5 onwards I can start enjoying rest of the juuni kokuki world.

Those like me who got here after watching anime version, I would recomend to start reading from vol 5 onwards because exept minor chances volumes 1-4 are... more>> very similar to the anime version. <<less

This.... just wow. This isn't, (whether it be the plot, characters, writing, or translation) on the level of most webnovels. I think it can honestly stand head to head with published novels by other Japanese authors such as Murakami. I first read this novel years and years and years ago, back when I had no interest in webnovels. This novel honestly has such deep and unique world building, realistic characters, thrilling action, survival, politics, and even little tinges of romantic tension. All the characters, and especially Youko is so... more>> well developed throughout the story, that it gives you the chills. The first novel deals with her loneliness, betrayal, and her slow immersion of her strength. The first volume focuses on the budding of Youko as the protagonist, becoming a timid girl to someone who has been shaped by struggle. Honestly, I could go more in depth, but I'd be here forever, and I have work to go do.

If you want a high quality piece of work to read, please read this. This is, imo, Isekai done right. This is something that was "Isekai" before Isekai became a thing. Think of it like Alice in Wonderland. The beauty of human imagination and fantasy are all in this novel.

I also feel like the translator, Eugene Woodbury deserves a special mention. He has such a clean professional site first of all, (with fonts mimicking a real book) so it really feels like you're reading with the physical book in your hand, which creates a special type of immersion. His translating, and control of the english language is honestly amazing. He's been working on this series for a very long time, I remember reading his translation about ~5 years ago and it was his translations that allowed me to get to know this series.

Honestly, I could go more in depth, but I'd be here forever, and I have work to go do. Bottom line is READ IT. I have no idea why this isn't more popular here. I suspect because the writing is not tr*shy, and you can't read it with your brain turned off, (which is what a lot of people come here looking for) they don't give it a chance. <<less

Great collection of character stories, with some of the best world-building imaginable and it is what got me into the "Kingdom Building" genre. Although I find some character stories more agreeable than others, I still appreciate how the author tried to make each Kingdom distinct, whilst being a part of a greater whole. I just wish there was more Youko Nakajima, since I would like to see how she would rule her kingdom, beyond just 3 years. Shame the series seems to be on "Hiatus", or it's just incredibly hard... more>> to find more volumes of it. <<less

Loved youko's stages of character growth and the plot devices used to bring that about. I couldn't put this down the whole time I read it. Definitely the best iv'e read in terms of character growth! My favorite was the monkey sword that tortured her with her own thoughts.
