A pivotal moment arrived in junior high school. Mie observed Kei interacting with classmates; their eyes met, sparking a friendship and partnership. Following the death of Kei's father, Mie and Kei held a private discussion under a tree, likely concerning entertainment aspirations. This led to their first collaborative performance in a classroom talent show, focused on acting.

Driven by their dream, Mie and Kei eventually moved to Tokyo. Before leaving Shizuoka, Mie's father gave her new clothes as a farewell gift. They departed together, waving goodbye to friends, family, and neighbors. In Tokyo, a mentor subjected them to rigorous singing and dancing training under challenging conditions designed to build skill. Their breakthrough came with an audition on the talent show "Star Tanjō!" Performing "Heya Wo Dete Kudasai" earned a standing ovation, overwhelming them with emotion and launching their professional careers as Pink Lady.

Reflecting on childhood incidents like the kindergarten fall or fish mishap caused Mie moments of embarrassment, though her outward reactions remained subdued. Her perseverance, evident from learning to walk to enduring professional training, marked her journey.
