The Ninja Outpost near the Land of Fire's border with the Land of Rain.
Kakashi was teaching Obito the Chidori. He could see that Obito was beginning to grasp Lightning Style.
With just a little guidance, Obito had quickly managed to form a rudimentary Chidori.
"Of course! I'm Obito, the Uchiha genius—the second-youngest Jonin in Leaf Village history!"
Obito laughed. But his carelessness caused the Chidori's technique to go haywire, and he grimaced as his own lightning zapped him.
Rin hurried over to check him. "Obito, don't get distracted while practicing Ninjutsu!"
Obito scratched his head and chuckled sheepishly, then told Kakashi the truth. "Kakashi, actually, it was Liao Wu's contraption constantly shocking me that unlocked my talent for Lightning Style."
Kakashi said dryly, "So you ought to thank Liao Wu for shocking you, then!"
Obito nodded, then shook his head. "Thank him for what? If I get the chance, I'm going to give him a serious shock."
Suddenly, a yellow figure appeared beside Obito and Kakashi.
Obito stared in shock. "Teacher Minato—"

Obito wanted to ask Minato.
But when he saw Minato's pained face, cold sweat beading on his forehead, he swallowed the words.
