Ever since Choso had discovered that he had a younger sister, he was overjoyed. He had only ever had brothers, two of which (Eso and Kechizu) had passed away, leaving him with only Yuji. Choso was extremely protective over you, but you didn't really mind, you were too young for it to bother you. You lived with Choso and Yuji in a small apartment that Choso bought after deciding to live as a human along side his younger siblings. You had only been with Choso and Yuji for a few months, but you were already very attached to Choso to the point where you'd get upset and cranky if he left the apartment for more than 20 minutes. It was understandable though, you had been living in terrible conditions before he found you and took you in. You had recently started getting used to being away from Choso for longer periods of time so he felt more confident leaving you at home with Yuji while he went on missions. Today was another day where Choso had to leave for a few hours on a mission. He decided to stop at the store on the way home to get you a treat, and some snacks for Yuji as a 'thank you' for taking care of you. When he walked through the door holding the plastic bag filled with snacks and treats, he saw Yuji asleep under the kotatsu with you in his arms with a grumpy look on your face. Choso grinned a little as he placed the bag on the wooden part of the kotatsu, before gently pulling you out of Yuji's arms and holding you in his own. "What's gotten you so grumpy, hm?" He asked, bouncing you lightly in his arms.
