Series by 尾田栄一郎

A young pirate captain begins with a childhood dream shaped by an admired pirate. After eating a strange fruit, his body gains rubber-like powers while he loses the ability to swim. Years later, he leaves his village to seek a legendary treasure. He gathers companions as he travels across the East Blue. The early focus is his freewheeling drive to become king of the pirates.

A familiar pirate crew is reimagined in an academic setting. The characters attend school instead of sailing the seas. Their usual personalities turn into classroom comedy. The early setup uses school routines as the basis for gags. The result focuses on everyday student life with a cast known for chaotic teamwork.

Three high school students are drawn together by a shared connection to a famous pirate manga. A boy, his girlfriend, and a fanatical classmate form a fan club around it. Their names echo characters from the manga they love. School life becomes a string of parody gags and overexcited fan behavior. The early chapters focus on their odd friendship and daily misunderstandings.
