This. Fucking this.
Karin was kept as a guard for the south base because she was a sensor ninja that had very few equals. She's able to sense a specific chakra from up to 10 km. She can also tell when someone is lying by fluctuations in their chakra, making her perfect for interrogations.
She's not related to Kushina, or the Uzumaki. She was chosen as a guard because no one could escape her sensor range. Quit being a dumbass, bat.
