5th Hokage
Tsunade, or Granny Tsunade as Naruto would call her, is one of the three legendary Sannins that was trained under the 3rd Hokage, also known as Sarutobi, along with Jiraiya and Orochimaru. Unlike Orochimaru and Jiraiya, she has incredible super-human strength and a bad temper to go along with it. Tsunade also happens to be the grand daughter of the 1st Hokage. She is a spontaneous person who loves to gamble, even though she is horrible at it and always ends up losing.
Her grandfather died fighting a great war when she very young, and everybody in her life that wished to become Hokage in the future, like her brother and boyfriend, also ended up dying. So she goes along traveling the world, with her student Shizune and Pig Ton-Ton, borrowing money from banks and loan-sharks to gamble and lose it.
