I'm assuming you're looking for an anime character that is a mail carrier dragon. Here are a few possibilities:

1. Pochi from the anime "Kemonozume" - Pochi is a small, dragon-like creature who works as a mail carrier in the human world. He's a bit of a troublemaker, but he's also very loyal to his friends.
2. Kaito from the anime "Dragon Crisis!" - Kaito is a young man who becomes the host of a powerful dragon named Dragon. As Dragon, Kaito takes on the role of a mail carrier, using his incredible strength and speed to deliver mail across the city.
3. Ryūjin from the anime "Ryūjin no Aji" - Ryūjin is a dragon who works as a mail carrier in a small town. He's a bit of a grump, but he has a soft spot for the people he delivers mail to.
