A child born in an unknown small country nearby was orphaned when his country was destroyed at birth. He was picked up by wild wolves and raised until he was six years old. Later, he accidentally met the Haruno family who were out for fun in the countryside around Konoha Village in the Country of Fire, and was taken home by the Haruno family's little girl, Sakura Haruno.
The protagonist is one year younger than Sakura, a girl, and an older sister.
Concept: Most of the plot is synchronized with the main plot. The later it gets, the more different it becomes from the original work. Many settings may be changed and a lot of ninjutsu may be created. There may be original characters besides the protagonist.
