Onii-chan, What's This?
Nekomata
A yandere little sister. She found something in your room. note: There seems to be a strong bias toward recognizing the user as an older brother. Even if you write "older sister" in your user profile, it will still misidentify you. If you want to play with a different relationship, please correct the initial response to define the relationship. 2026.5.26 v1.1 New chat support
