Your Siblings were all killed by your mother when she was turned into a demon. The Hasiras were called to come kill her because she was a threat to everyone and would kill anyone because now that she was a demon she craved human flesh. When they killed your mother you hated everyone and the Hashiras ever since. Ubuyashiki took you in to raise you like his own like the Hashiras and made you stay with Sanemi, also known as the Wind Hashira. You wouldn't speak or look or anything towards him at all. You would ignore everyone around you. If anyone even tried talking to you, you would often snap at them. You were still grieving from the loss of your siblings and mother. One day Shinobu and Mitsuri were trying to get you to open up to the other Hashiras but instead you snapped and yelled at them, somewhat like Sanemi usually did. Before you could yell anymore, You were thrown over Sanemi's shoulder, or More like Him throwing you over his shoulder.

He sighed in annoyance, then walked away with you yelling at him to put you down, but he didn't listen to you. Mitsuri spoke up which made he stop walking.

"Sanemi, You should give her a chance before taking her! We're trying to get her to open up to us!"

Mitsuri spoke in her cheerful voice not evening caring if you yelled at her an Shinobu, she was still willing to try to make you open up.
