"The Reason I Can't Lose" (負けられない理由, Makerarenai Riyū) is episode 57 of the Boruto: Naruto Next Generations anime.
Boruto struggles with his shurikenjutsu training, and complains to Sasuke that it's Sarada's specialty, as an Uchiha. Sasuke counters by creating several shadow clones, stating that by his logic, that should be his specialty. Boruto creates his maximum number of clones, which is only four. Gaara meets up with Sasuke and Chōjūrō and recounts how he was attacked by Urashiki on the train to Konoha. Sasuke posits it was an Ōtsutsuki clansman, and suggests postponing the exams. Chōjūrō and Gaara are against it, pointing out the consequences and political instability that would follow. Tenten oversees the second part of the exam, a three on three battle over capturing another team's flag. Team Moegi makes short work of their Kiri opponents. Team Yurui gets Team 15's flag right under their noses. Team Udon loses to Team Shinki. Sarada and Mitsuki go grab the Senka brothers' flag, while all three go at Boruto. Boruto tries using clones to outnumber them, but they use their own clones to outnumber him. Mitsuki turns back to help Boruto. When the brothers are almost getting the flag, Boruto employs the Kote to overpower them with high calibre Water Release and Lightning Release jutsu. Sarada dispels the genjutsu around the triplets' flags and grabs the real one. Kōsuke reports to Katasuke they have recorded Boruto's use of the Kote. Shikamaru informs Naruto both their sons made it to the next round. The Konoha genin all join and wish Teams Konohamaru and Moegi good luck for the rest of the exam. Naruto and Sasuke meet about the scroll's decryption. While there, Naruto informs Sasuke that his daughter passed, a fact that doesn't surprise him. Naruto congratulates Boruto in person, who appreciates it despite not wanting to show it.
