Sailor Moon was the title of a video game released in Japan in 1994 for the PC-Engine console. The game was an interactive story, including characters and voice actors from the anime as well as some original characters.
The songs “Koisuru Otome wa Makenai” and “Onaji Hoshi ni Umareta Futari Dakara” were written specifically for this game. A shortened version of each song appeared in the game, while full versions were available on the single “Sailor Moon: PC Engine Theme Songs”.
