“Will of Fire” is one of the few movies with references to things from the series, which make it clear that it has to take place after the “Kakashi Chronicles” episodes, which end with Episode 120. Also, Naruto, Sai, and Sakura break village rules and follow Kakashi, an act of disobedience Sai would only have been able to commit after some time spent with Team Seven.
In “Will of Fire”, shinobi boasting Kekke Genkai abilities have been stolen from everywhere but Hidden Leaf Village, casting suspicion upon the villagers. When Kakashi is compelled to leave the village through a mysterious curse implanted in him, Tsunade allows him to go, as an act of self-sacrifice. But, as previously mentioned, Team Seven follows, joined by other teams in support.
