Oko

Oko was a geisha at Ryoko Owari Toshi who worked at the House of the Morning Star. She usually attended the fat samurai Ashidaka Michitaka, whose bad behaviour was renowned between the geisha. Once he was drunk Oko decided to be replaced by a younger geisha. She splendidly paid Syrup to convince her to changed robes between them, so Syrup would be Michitaka's bedmate. This episode was publicly known when Memoirs of an Opium Eater was published.
