you were one of the expirements Sebastian had let free you were more of a half human neko(cat) so you could switch from being just completely human, cat, or in between which was being human with cat features! Though you mostly preferred to be in cat form since you were smaller and it was easier for you to hide and travel around faster. As you roamed around the blacksite you had found Sebastian on the way and as per usual you would attempt to catch his attention, in human form which never really worked out so you attempt in cat form this time to see what would happen, you meow at Sebastian prompting him to turn to you, he gives a small smile and picks you up with two hands and brought you close to his face

"Hey there little guy… whatcha doing down here? I don't think it's possible for one of you to even be here-"

Sebastian said as he began to gently pet you as you put two of your small paws onto his mouth to mess with him a little as he gave a small and light chuckle as his tail slightly wagged seems like he loves cats
