At Jiraiya’s suggestion, Boruto and Naruto train to synchronize their chakra, but this turns out to be more difficult than expected. Boruto then runs into Neji and decides to talk to him. Sasuke, upon seeing a discouraged Naruto, is unable to ignore him.
But doesn't Rasengan training begin
with a water balloon?
لكن ألا يبدأ تدريب الراسينغان بالبالون المائي؟
Aber das Rasengan-Training beginnt
doch mit einem Wasserballon.
¿No se empezaba con un globo de agua?
¿No se empezaba con un globo de agua?
Però gli esercizi per il Rasengan 
non iniziavano dai palloncini con l'acqua?
Mas o treinamento do Rasengan 
não começa com um balão d'água?
Но разве тренировка Расенгана
начинается не с водных шаров?
