Now we are talking about animation and art that is used here. Nothing groundbreaking or spectacular but it still have it's up and down. The best aspect here must be character design an important part on harem genre. Every character is drawn very attractive and very pleasing to the eyes. The downside here sometimes the background is not moving. But overall it is still good.
About sound even though most of main cast played by rookie seiyuu but every one of them play good job and match the character they are playing. The best must be Yuuki Kana VA of Rinslet which bough up her ojou aura more than her LN counterpart. And about soundtrack it is decent but I still disappointed that Shukasai no Elementia the one used for PV is not used as ED or OP instead.
Now the most important part of harem anime is character. We are starting with our main character first Kazehaya Kamito. As the only male spirit contractor in the series people are wary about him because in history the only male spirit contractor Demon King and as you can guess it create chaos in the past. He have good nature personality but is not above teasing his harem member. He is also competent fighter and neither wimp nor (really) dense character. Now move on to Claire. She is tsundere with heavy dose on tsun than dere. Thoughit can be annoying sometimes but over the time she really grow and become more likable. She also have rival and childhood friend named Rinslet. Rinslet like Claire is also tsundere but instead of tsundere to our male lead she is mostly tsundere to Claire. She is also have the most ojou appearance and voice in the series. Move to another character we have Ellis who is also tsundere who lean more on dere than tsun. She is serious and upstanding person. She is also act according to knight honor. We also have Fianna. She is princess also she is the tease on the series. As one of a few character that know Kamito secret she always take advantage on it. Next we have Est. The best character on the series. Bold, cute and charming. She is also very powerful spirit and Kamito trusted partner. The most defining trait of her character is that she like to wear nothing aside for knee socks. Now for the last we have Restia another spirit character. The most mysterious character on the series and the driving force behind the series. What she think and what she do is always mysterious.
This is relaxing and enjoyable series overall but since I've read the LN I know very well that Blade Dance haven't reach it's full potential yet. I'm definitely recommending this to you who like harem fantasy or who like lighthearted series in general.
On a side note the main story start right after anime end so for those who like this adaptation enough I'm strongly recommending read the LN. You can start at volume 4 where anime left off but I think it's better to read it from the start.
