Uonome (ウオノメ,Uonome?) was the leader of Majisuka Jyogakuen's Team Hinabe and a member of Katsuzetsu's Rappapa. Her jersey has a nametag with Juri (朱里,Juri?) written on it. She was given the Genji Name Iwashi (いわし,Sardine?) in Cabasuka Gakuen in which her surname was also revealed to be Takahashi. She has a younger sister that looks like her called Ikanome.
Iwashi celebrated her "true birthday" on Cabasuka Gakuen Episode 7 which was aired in Hulu on 2017 December 18 (2017 December 11 on NTV), but her actress' birthday is on October 3 (3½ weeks before Cabasuka Gakuen aired).
Before that, Kurage used Iwashi as an example to the others on Cabasuka Gakuen Episode 2 (Hulu airing: Oct. 30; NTV airing: Nov. 6) in using their birthdays by telling President Nakabayashi that it was Iwashi's birthday that day.
