During the journey to the war alongside Ay, Naruto, and Killer Bee, Tsunade doubts her belief in Naruto. She recalls a past encounter with Ay, who required her medical skills to treat an injured subordinate. Tsunade agreed to provide aid only if Ay could defeat her in an arm wrestling match. Ay won the contest by utilizing his speed. Following the victory, Tsunade examined the patient and demanded to know the circumstances surrounding the injury. This flashback highlights the history between the two leaders before the current conflict. The narrative is part of the Fourth Shinobi World War: Confrontation arc, specifically episode 25 out of 53.
