Usa-Chan is the favoured toy of "Honey" (Mitsukuni Haninozuka), the young-looking member of the Ouran High School Host Club. As the name implies, it's a toy rabbit.
It has been modeled as a prop by Aihara-Awayuki, and is available at https://aiharayukii.deviantart.com/art/Usa-Chan-version-1-0-211979116
The readme in the download does not include license terms. However, unless you happen to be Bisco Hatori (the author of Ouran High School Host Club), it would be best to use this prop in non-commercial fanart only.
