Forgetting about fame, she offered her healing materia to help those wounded after the lifestream had passed through Wutai during Meteorfall. After a while a strange epidemic arose and, believing Yuffie to be the carrier, her father locked her within the family dojo to both quarantine her and protect her from the townsfolk. Freed by Yuri, a childhood friend, the pair left Wutai to investigate the materia caves for a cure for the "Midgar Disease". Calling via cellphone but unable to find an answer on whether one existed from Cloud or Tifa, Yuffie and Yuri explored the newly opened caves from when the lifestream erupted from the earth. While finding no materia within the caves, the pair encountered many monsters. A stray fireball released a black liquid from the ground, which appeared sentient, and chased Yuffie and Yuri out of the cave, where it infected Yuri with Geostigma, Yuffie has teamed up with Cid Highwind and Nanaki to head to the northern materia cave in search of a materia that might cure Geostigma.
