Buffalo Bell (バファローベル) is the sister of Buffalo Bull, as well as the second mascot for the Orix Buffaloes. She has been nicknamed BuBell, or Bell-chan by fans.

Bell has probably had the most commercial success out of all Japanese mascots, as she has a very large amount of merchandise, including a photo album and a PVC figurine.
