Courier ninja.
A courier ninja's job is similar to that of postmen in that they deliver mail. According to Courier Ninja 596-03, they are professionals who risk their lives to deliver goods to the customers. The only differences between postmen and courier ninja are that postmen don't risk their lives while courier ninja do. Letters and packages are also much safer with courier ninja as they are known for their efficiency and outstanding records. However, they're overzealous in their deliveries, not even stopping when told they're delivering the wrong packages.
