Hito Shihōin

This unnamed Shihōin boy was the younger brother of Fujoshi Shihōin and the son of the unnamed Shihōin clan leader.

Background
This boy was one of the heirs to the Shihōin clan, but, at the age of nine, was killed along with his clan (save his sister, Fujoshi), when the Yama Clan attacked Yamagakure and eradicated the Shihōin.

Trivia

 * It is because of his death that Fujoshi resolved never to use ninjutsu.
