I loved this anime!! I felt it was done very well, however in some parts Nanami seemed to drivnig in the direction of a Mary-Sue but she always manages to go the other way again. I wish there would be more anime like this; I loved it!
My opinion of the characters are that Tomoe was definitively the best leading male in the series. I don't particularly like him but the way he was done make him enjoyable and a little lovable. The episode when he becomes a chibi I was in heaven with that Tomoe! I wish he could have stayed that way but all good things must come to an end.
Kurama was the actual reason I started this anime. I'd seen his character design and wanted to check it out. And I was glad I was not disappointed! I love his character and his looks~!
