A shoulder wound shouldn't stop an ANBU shinobi.

Loving the story so far but I believe you made an error in the time line. Iruka was just starting academy when his parents died, so he couldn't be an instructor just 2 years after their deaths during the Kyuubi attack. Even Uchiha Itachi joined the academy at age 6 a year after the attack but Nessa is joining at age 3?

I love this story, it's very interesting so keep up the good work ! :)
