What do you think makes this series so popular?

I think that Furuba is a popular as it is for a number of reasons one being the characters,their pasts and how there's so much depth to each and every character,how it's not only just sad,it still some funny parts and how it just doesn't give the same feeling all the time it gives you a number of different feelings in different mangá volumes/episode! random picture of Shigure-sama's imagination featuring Kyo-kun! all I can say is poor urso :p

I think it's the characters, the dialogue, and the plot ^^

I think It is a Anime/ mangá with unique Art style and great Plot and Storyline. The Characters are also unique and lovable. I think it is what a perfect animê should be, It has Comedy, Romance, Fun, Madness, Happiness as well as it's emotional, it makes us cry and at the end teaches us so much about Life. ^^

The complex plot and the characters. Natauki Takaya obviously wasn't making stuff up as she went along, and she makes your coração go out to all the characters and couples because they've all had such terrible pasts and you feel like the two in the relationships really deserve each other.

I don't know about other people, but I watched this show because I knew the pain some of the other characters were bearing. I kept watching and watching and the show changed me. I used to be a terribly mean person, but now I realize that I need to be a better person like Tohru. Now I'm working on being a better person. Throughout the past few years, I have become way better.
