If I am asked to describe it in 3 words, I would say:
1. Gentle 2. Kind 3. Friendship
It is about friendship, which lasts. And, which overcomes all the difficulties. What if your bestfriend tells you that she is in love? In love with a girl?... Does it change your friendship? If yes, how? If not, why? It is great to have a friend, who will support you no matter what. And I would like to highlight that the main theme of this anime is friendship between two girls. And hatsukoi (first love), which they experience is beautiful, but the most important is
to see how they support each other. Real friendship between young women is gorgeous and very rare.
Opening song is very gentle and soft. A singer has a unique voice, which 100% fits the story. Ending theme is a nice slow song, which is adorable. Music in this anime is great and enjoyable!
Gentle and shy Fumi-chan and happy and energetic A-chan are like ice and fire. It may seem a bit cliche, as there are many these kind of characters in anime. But in Aoi hana there is no antagonist, the "bad" person, every character is great in it's own unique way.
At first character faces seemed a bit strange to me, but after few episodes, this doesn't matter anymore. A background image does suffer, as it is not detailed enought. But maybe it was done to capture viewers attention on the story and not on the image details.
This anime features classics. Firstly, Wuthering Heights, and if you read this book and love it, you would enjoy this series a lot. As Erica Friedman, the president of Yuricon and ALC Publishing said: "Aoi Hana could easily be compared to a Jane Austen story", and he feels that the story is not "a melodrama or a parody".
Overall, I'm enjoying this series a lot. I have never thought that shoujo ai genre would interest me, however I was wrong. It is a gorgeous story, which should be admired by people, who love slice-of-life anime.
