Tegami Bachi: Letter Bee

One day Lag Seeing finds himself shipped. His mother abducted by someone, he's now just a package sent by her to be delivered to a friend's house. Gauche Suede is a Letter Bee, a member of the Amberground national postal service, who is tasked with delivering this "letter," together with his partner Roda. The still young Lag rebels at Gauche's seemingly emotionless focus on his work, his heart still reeling from being torn from his mother, but as they head into a valley they are attacked by a ferocious creature known as a Gaichuu.

Lag, having glimpsed into Gauche's heart, comes to know about his dream to be chosen for the highest title the Bee's that work in the capital can obtain, Head Bee, and that he will soon be transferred there, a first step toward that dream. Nearing the end of their journey, one day before reaching their destination Lag and Gauche get in a fight after Lag asks Gauche to take him with him to the capital so he can search for his mother. Angry, Lag takes off with Gauche's shindanjuu and hurries along by himself, but wanders into Gaichuu territory without realizing it and falls into a trap.

Some years after he met Gauche, Lag heads to the main post office in Yuusari to take the interview to become a Letter Bee after passing the preliminary examination. After saying all his goodbyes to the people he loves, he heads to the train station with a Letter Bee named Connor that came to pick him up. But when he arrives, he discovers a small girl hiding herself in a small crevice. And what's more, she's a letter, just like Lag was!

Lag gave the name "Niche" to a girl that was a letter whose delivery slip was incomplete and couldn't be delivered, and started taking her to her destination. Lag is enchanted with her hair while he escorts her, and on his way after dropping her off, he learns from some passersby that her destination was actually a freak-show, advertising a new attraction: A child who received the blood of the legendary creature "Maka."

Lag, as well as Niche and Steak, a strange animal that tags along with Niche, reaches the town of Kyrie where the bridge Bifrost connects to Yuusari. There they meet Nelli, who guides them to an inn to stay the night, and volunteers to take Lag's bag up to his room, but then suddenly disappears. Nelli's aim is actually to get Lag's crossing pass into Yuusari.

Lag and Niche run after Nelli to get their crossing pass back, however Nelli is found out as an impostor and is going to be punished! Lag and Niche come up to save Nelli, but just then the letter Nelli's late brother Nello wrote to Jiggy Pepper flies away. Lag stretches out his arm with all his might trying to save the letter, and suddenly a shindan flies out from his hand!

Lag Seeing, who was rescued at a young age by a national postal service worker known as a Letter Bee named Gauche Suede, idolized this Bee and finally met him again after he went missing. However he calls himself the Marauder Noir and steals the letter from Lag. Lag, injured, is saved by the Express Delivery Bee Jiggy Pepper and taken to the Bee Hive, but Lag's partner, his dingo Niche, doesn't take it very well...

Niche thinks she has failed at being Lag's dingo, so she runs away from home with her pet(?) Steak. Worried, Lag and Connor head out to search for Niche. However Niche, hungry and wandering aimlessly around town, sneaks into the bread and weapons shop Sinners and tries to finally cook Steak, but the Gobenis catch her in the act.

One day, while on a delivery to a certain mansion, Lag is asked by Ray Attlee the owner of the mansion, to search for the person who sent a picture-letter to her. Ray says that the pictures in the letters reminded her of her hometown, and gave her the will to continue to live on and fight her illness. Lag, after being called a "Letter Specialist" by Ray, decides not to rely on his shindan that allows him to see the heart contained in letters, and does his best to search for the sender. He discovers that the paints used to paint the letters have some connection to Ray's hometown, and then...

"Get away from here"... The boy Lugh works together with an old man he calls "Grandpa" in an imagery lighthouse built out in the wilderness, but he keeps hearing voices from somewhere. Around the same time, Jiggy Pepper is passing by the area on a delivery, and notices that a Gaichuu, Korona, has made a nest on top of the imagery lighthouse. Riding his "iron horse" up the imagery lighthouse, Jiggy Pepper's shindan Lapis Lazuli explodes!

Two inspectors from the capital, Akatsuki, come to the Bee Hive. Caribs Garrard and his dingo, Hazle Valentine. They came to investigate a string of letter robberies happening to the south. During one of them, Moc Sullivan is attacked, and the letters he was carrying fall into a ravine. Garrard suspects that there's someone on the inside for Reverse, since they know so much about the Letter Bee's routes and movements, so he forbids them from going to the south. However, one of the letters Moc was carrying was a letter from a sick girl that Lag dictated for her...

Sylvette receives a fan letter addressed to her from a girl named M. Croce, asking her to make a doll that looks like her to give to her brother who will be leaving his hometown to work in a coal mine shortly. The doll maker, Sylvette, hurries to make the doll, and after spending all night, heads out the next morning to deliver it. Lag is worried and goes with her, but the two of them are tired and end up falling asleep on the rhino carriage!
