Characters
Sentaro Daimonji
Ranma first discovered Sentaro while he had been knocked unconscious while riding his horse into Tokyo one afternoon. When he awoke to find Ranma (a girl at the time) he thanked her for saving his unworthy life, and slipped some paralysis power into her tea, and quickly kidnapped Ranma and took her back to his home where he announced to his Grandmother that he had found his new bride.
Sentaro is a master of the Martial Arts Tea Ceremony and believed that he was engaged to a monkey named Satsuki. He asks Ranma to defeat the monkey so he can get out of the engagement. Ranma agrees and the two fight until the real Satsuki Miyakoji arrives. Satsuki had gotten pre-wedding jitters and sent her monkey, Sanae, in her place. Thankfully once they met both Sentaro and Satsuki fell for each other and Ranma got off the hook.
Sentaro appears much later (and much, much more often) in the anime than his one brief appearance in the manga.
The Meaning Behind the Name - 大文字煎太郎
Sentaro (煎太郎) means "boiling thick son," which may be a reference to the fact that he is about to inherit his family's legacy. Daimonji (大文字) is "(大) big + (文) literature + (字) letter/character".
