Chapter 1: A New Mission

Monkey D. Luffy, son of the Revolutionary Dragon, and grandson of the Marine Hero Monkey D. Garp, joined the Marines at the age of 14. He received training from his grandfather himself. After two years of training, Luffy was promoted to a lieutenant of the Marine Headquarters and sent to East Blue, where he spent his early years.

He is ordered to recruit his crew himself, because his grandfather persuaded Fleet Admiral Sengoku to do that. Luffy has arrived in East Blue, and he is going to start his mission to protect the innocent.
