Story: 9/10
Although Tegami Bachi may seem extraordinarily childish at first, the subtle, dark undertones are what make it very appealing.
Amberground, the setting of the story, is divided into three sections based on social class: Yodaka, Yuusari and Akatsuki. The land is covered by darkness with the exception of the artificial sun with illuminates the capital (Akatsuki); therefore, the farther away you get from the capital, the darker it gets.
Lag Seeing, an orphan, was found by a Letter Bee, Gauche Suede, who realized that Lag was the package he had to deliver to Campbell Litus, a small town in the dark Yodaka District. To Lag, Gauche was like a hero - he had saved his life numerous times during the delivery. Gauche was also the one who taught him about how letters hold the hearts of those who write it, and how the gaichuu (giant insects) are out to steal those hearts. Overshadowed by his hero, Lag swears to become a Letter Bee when he grows up. Only, when he finally achieves his goal, he discovers that the person who inspired him is no longer working as a Bee. Desperate to see him again, he begins to search for Gauche during his deliveries. In the process, Lag learns of an underground organization plotting to overthrow the capital, and the price that the citizens of Amberground pay for the artificial sunlight.
Art: 8/10
Studio Pierrot has done a pretty good job with the animation. All the colours look very comfortable and eye-pleasing, with fabulous openings and endings.
Sound: 10/10
I really like the music in Tegami Bachi because it really adds to the story. Each piece of music was carefully planned out and they really suit the setting of the story.
Character: 7/10
This is where I really think the story is lacking. Lag is an annoying crybaby who really, is nothing more than annoying. Niche, Lag's dingo, does incomprehensible things almost every episode. Gauche is the only one who has a relatively deep character, that enables you to understand his thoughts and motivations. The occasional flashbacks do help explain Gauche's character, but in general, you can't really relate to the characters.
Enjoyment: 8/10
The light mood mixed with the dark undertones make a nice blend.
Overall: 8/10
