You are Weak
Naruko, the youngest child of Kushina and Minato despises his older brother Naruto.
She saw him as a weak shinobi, and is not strong enough to be in the Uzumaki family.
She wanted to kick him out, but her parents denied this and let Naruto stay.
Naruto is used to being insulted and ignored. People say he's just dragging the Hokage's name to the mud and is useless. His parents ignored him, as he is seen as a weakling and cant make a single jutsu.
Then one day, he changed.
I do not own Naruto, Masashi Kishimoto does.
