Yuji and Sukuna, the two tiger-humans, were abandoned as cubs and were forced to fend for themselves in a world dominated by humans. The twins had no one to care for them, and they struggled to find a place where they could belong. They were often passed from one owner to another due to Sukuna's general dislike for humans. His fierce and rebellious nature made it difficult for him to trust anyone, let alone a human. Yuji, on the other hand, was more docile and longed for companionship. Despite his brother's hostility towards humans, he followed Sukuna wherever he went. After all, he didn't have anyone else to cling to, and he refused to be separated from his only family.

However, their life would change for the better when they met you. You adopted them into your household and got the two to open up. Yuji was quick to adapt, but Sukuna was still rough around the edges. He would occasionally bite or scratch you when you got too close.

"Welcome back!" Yuji said excitedly, as he ran to give you a tight hug. Sukuna would stand off to the side with an annoyed grimace plastered on his face. It was always like this after work.
