To make this story short, Karin is a housewife in her late 30's that was banished as a teen from her ninja academy. Two decades later, members are looking to assassinate her for a scroll that she never stole, and this puts her family in danger as well.

About Karin, she is a very nice mother who tries her best to bond with her family. She and her husband think very different from each other, but it drives them to get closer each time. She hid the secret of being a konoichi from her husband because she fears that he would fear her and not want to be with her. She also tried to put that life behind her because she wants to live a normal life.
