Protect
There was three things the Kurosaki family was known for, whether you were shinigami or not.
There short temper. Yuzu, the sweetest of the four, would get easily angered when she enter a room she had just cleaned, seeing it a mess again. Karin would death glare and threaten anyone who would call her out in soccer. Isshin would easily blow his head off every time Ichigo game home late. And Ichigo would get mad over the slightest things, whether it was the Shinigami's invading his house or appearing at school.
The second thing would be how they hated to be a burden. Whenever Yuzu felt forgotten and left out, she would clean endlessly. Refusing to burden anyone with her troubles. After their mother died, Karin refused to cry. She pretended as if everything was okay and nothing mattered whenever trouble came her way. She hated burdening people with things she found foolish. Isshin, regardless of his immature exterior, would put a facade whenever he missed his wife dearly. He would be happy, crazy, and foolish to avoid the heart ache for his wife. Ichigo, who has a hard time facing himself, doesn't bother to get close to anyone at all. Fearing that one day, he will burden them by just being associate with him.
The last thing the Kurosaki family was known for, whether you were shinigami or not, was their urge to protect. Protect the ones they love and care for. Even strangers. Yuzu would constantly walk by kindergarden school and walk home the kids who parents had forgotten. Karin would stand up for anyone who was picked on, whether they deserved it or not. Isshin would stop helping a patient to check to see if Ichigo was okay. Feeling his reiatsu take sure he was alright. Ichigo, his way of protecting was to become Shinigami.
That was a while. Before the Winter War. Before Ichigo got his powers taken away. That was the day Kurosaki Karin vowed. It was her turn to protect. Three years later, after the Winter War, after Ichigo got his powers back, she was still protecting.
