I had at first started reading this manga because I was interested in the title, wondering how the manga correlated with the Mark Twain's character of the same name. I did not expect to much from the manga, just a light quick read, but I greatly underestimated this work!
Plot- Based off the book "The Adventures of Tom Sawyer"  this manga has some of the same events as in the book, however it is also very different so it was not just a manga adaptation of the book. There are so many wonderful additions to the plot that made it very unique and interesting in its own right.  The plot was well paced, and enjoyable, having a slice of life kind of feel while remaining relatively exciting with unusual occurrences and in the end very edge of the seat.
Characters- The two main character's are very well developed, all the character's are quite well developed. The character's themselves are quite interesting in their own regards, but it is the relationships between them that makes them even more interesting. I really liked Haru as a character, she was very realistic and I enjoyed watching her interact with the other villagers. I just can't find words to explain the wonderful relationships between all the different character's!
Art- It's very beautiful and fits this work perfectly! It's light, airy, sketchy, fitting the slow summer day lazy kind of feel that is the deep undertone of the whole novel, however it also can become light and dreamlike for the times that seem just like that. It also was able to pull off a more darker feel for the times it needed to.  The style portrayed the story beautifully, and really added to this manga.
Other- I really can't describe this manga well enough, there's just this... this really wonderful part to it that I can't capture in words! The relationship between Haru and Taro is beautifully innocent, their unique friendship is one of a kind and I really enjoyed watching these two's experiences together. Definitely recommended!
9/10- Was Good
