In the late 20th century, there lived a 15-year-old girl named Yohko Yamamoto. Her unique cat-like eyes and love for playing video games and snacking on Pocky were well-known. Due to her exceptional skills in arcade shooting games, Lawson hired her to operate the advanced spacecraft TA-29, which would take her one millennium ahead in time. In her interstellar adventure, Yohko led the Terran team, consisting of Ayano Elizabeth Hakuhoin, Madoka Midoh, and Momiji Kagariya, to battle Rouge and Ness' infamous Red Snappers.
