Usagi Yojimbo is a comic book series created by Stan Sakai. It is set primarily at the beginning of the Edo period of Japanese history and features anthropomorphic animals replacing humans. The main character is a rabbit rōnin, Miyamoto Usagi, whom Sakai based partially on the famous swordsman Miyamoto Musashi. Usagi wanders the land on a musha shugyō, occasionally selling his services as a bodyguard.

A bodyguard is a type of security guard, government law enforcement officer, or servicemember who protects a person or a group of people — usually witnesses, high-ranking public officials or officers, wealthy people, and celebrities — from danger: generally theft, assault, kidnapping, assassination, harassment, loss of confidential information, threats, or other criminal offences. The personnel team that protects a VIP is often referred to as the VIP's security detail.
