Sansho

is an academy student from Konohagakure.

Personality
Sansho gets along well his classmates Tsukune and Mibuna. Like Naruto he is a troublemaker and likes to pull pranks. When Iruka initially questioned the group he feigned ignorance and stated they were only playing hide-in-seek. However, he appears to have some sense of right and wrong as he and Mibuna decided to run when Tsukune wanted to steal the Scroll of Seals.

Appearance
Sansho has short, greyish-brown hair and black eyes. His attire consists of a light orange vest and a purple cap on top of his head.

Konoha Hiden: The Perfect Day for a Wedding
Sansho, Mibuna, and Tsukune perform some vandalism around the village. When Iruka catches them in the act, they claim to only be playing hide-and-seek, but he tricks them into confessing. Iruka remarks that Naruto Uzumaki was a much bigger delinquent when he was a student, which Sansho and the others don't believe.
