I'll admit. I'm late to jump on the bandwagon, even though an old friend of mine recommended this series to me, what...
5 years ago?
Well, I just finished watching the anime last week, and I must say I'm in love. I haven't read the novels, and probably don't have the patience to do so online. I may in the future, however.
If anything, the one thing that really struck me about this series is, fantastical context notwithstanding, Youko is going through something that almost every young adult faces--simply growing up and learning who you are as a person. A lot of the wisdom I heard in this anime I actually took the heart. I tend to love this style of anime as they're usually visually appealing. As for Juuni Kokki, it appeals to me visually, yes, but more so emotionally. I'm glad to have found it.
And even more glad to be amongst other fans who love it, too! ^^ Hello everyone, it's nice to meet you. I hope I'm not too late.
