Naruto no diff
Why? Sexy No Justu
I heard he liked Sasuke the most
He loved Minato as a Brother. He was his Student and teached him all he could. In the end they had an insane friendship.
Nagato was like a adopted son. He felt like he's responsible for him,
but after all Naruto was like a Son. He was like him, taught him everything and even surprised him with his personality...
if he saw him now he would be proud... nothing goes above the love to a child
Correction... Jiraiya treated Minato and Naruto as son and grandson, respectively but I believed Naruto was his favorite pupil due to exceptional many similarities especially their pervert persona.
