Kakashi Chronicles ~ Boys' Life on the Battlefield ~ Part 1

Kakashi Chronicles Part 1 rewinds to the past: a young Kakashi, newly a jonin, leading teammates Obito and Rin on a wartime mission during the Third Shinobi War. The episode is canon backstory, establishing the rule-obsessed prodigy Kakashi was before loss reshaped him, and the bonds that defined Team Minato. It's the setup for the Kannabi Bridge tragedy — the mission that gives Kakashi his Sharingan and his philosophy. The flashback that explains the man fills in the history every later Obito revelation depends on.
