The chapter/episode where Danzo was made temp Hokage, and the episode where Hiruzen was put back into the Hokage seat after Minato's death. Also the fact that Neji was made Jonin right after becoming a Chunin too. Gaara was promoted to Chunin at age 14, he either became Jonin then Kage at 15 or Jonin at 14 too, then Kage at 15. There are plenty reasons when you consider there was no Kazekage and Gaara was the just about the strongest Suna shinobi after his father died.
