Oshima Yuka (大島優香?) is one of the sisters of the deceased former leader of Rappapa, Oshima Yuko. Along with their other sister, Oshima Yuki, they transferred to Majisuka Gakuen by request of their late sister. The Oshima siblings were all portrayed by Oshima Yuko.

Appearance and Personality

Similar to their late sister, both Yuka and Yuki acts and fights in the same manner, the only difference can only be seen in their accessories and their gestures. Yuka can be distinguished when she uses her right arm in her every gesture, her chain accessory can also be seen on the right side of her skirt.


At an unknown point in time there was a disagreement within Yuka's family, Yuka and Yuki got seperated from their eldest triplet sister who moved with their grandmother instead. They didn't have much contact with her, but it was certain that they tried several times, as Yuko then surprised them when she called them a week before her death with a request to meet up with Maeda Atsuko.

Yuka and Yuki transferred to Majisuka Gakuen to deliver the message of their eldest sister to Atsuko, who became obsessed in finding the answer to Yuko's request. They startled the new Rappapa members in their appearance because of their similarities. They also interrupted the fight between Center and Gekikara, as a new threat had arrived. After delivering the message to Atsuko, the latter asked if she could hug her, Yuka reluctantly agreed, annoyed and laughed in the fact that Atsuko really wanted to hug her as Yuko. When the police were on the hunt for Atsuko, Yuka and Yuki told her to hide and planned her escape. They then went to assist their Majijo sisters in their fight against Yabakune.
