''Article from Yukikos's main page''

Yukiko was born as a human baby, she had her father and mother like any normal girl.
At the hospital where she was born, someone changed the names of the babies and they stole little Yuki to take her to a pharmaceutical facility.
Once there, they injected her with modified wolf DNA, which caused various external features to change as he grew, such as her face, hands, and even made her grow a tail the same length as her body. As she grew, so did the tail.

She was trained along with other children also stolen from different hospitals so that in the future they would serve the military in the different international conflicts that might arise.
One day, a very special friend of Yukiko's ended up badly injured due to one of the routine training sessions that they used to do and she couldn't survive.

Yukiko could not bear living such a loss and due to the fury that arose from that loss, she transformed into her beast form, something that these facilities were not prepared for, so she ended up fleeing from there without too much complication.
