Oshima Goketsuji first became playable in Power Instinct 2. She is a part of the third Goketsuji generation. At an early age, Oshima showed uncommon abilities for a little girl. She spent 15 years of her young life studying and training martial arts in the mountains and later began her labor as shrine maiden. According to an interview with the development team of Goketsuji Ichizoku 2, her design was inspired on Lady Miyako from the anime film Akira.

FUN FACT: When the CPU selected Oshima, she appears in an orange and green color attire that was unselectable by the player. This palette swap became selectable in Power Instinct Legends.
