Body-Tempering Naruto

Naruto Uzumaki had been treated with cold indifference by the villagers since childhood, and had always hoped to make friends.

Then, one year, a Body-Training System bound itself to him. The System told him, “Only the strong deserve friendship. Train your body, Naruto, and you'll have lots of friends.”

Half-convinced, Naruto began his body-training journey.

Later...

“Naruto, will you be my friend?”

On the ground, battered and bruised, Uchiha Sasuke asked Naruto in humiliation.

Hearing this, Naruto unclenched his fist, warmly pulled Sasuke to his feet, and said with a smile, “Of course. I accept you as my friend.”

This is the story of Naruto Uzumaki going down the wrong path.
