I have read all 12 books of this series and I think it was very succsesful! I liked the story line and still read it over and over again! The story is a little...um...dark, but it's just interesting. It's one of those manga that has a lot words and you HAVE to read word for word or you will get lost. It's word heavy, but cool. Still love it and very much enjoy Tsugumi's and Takeshi's work! (I also LOVE their series BAKUMAN!!!)
I have read up to the 3rd book of this series and WANT to read more! I absolutly love the idea of delivering peoples letters, which are written from the heart! I love how the main character cries for other people's sake and not his own! I love his dingo's Niche and Steak! This story about Lag seeing and his adventure as a letter bee is truly fantastic! I have a LONG list of manga to read, but I WILL fit this in!
