Debut: Episode 8 "The Art of Altercation"
A brunette with dreamy eyes, a penchant for quoting proverbs, and a "Sweet Tooth for Grapes" (the source of her given name, which translates literally as "grape fang"). Although Nagamitsu, her husband, calls her Osen, "Budoukiba" is her name.
She first appears in the restaurant scene plying Jin and Mugen with a round of sake.
