Aoki joined in 1995, where her first tracks were arrangements for the fifth generation console ports of Mega Man X3. She then lent her voice to Mega Man Battle & Chase, providing the vocals for Roll's special ending theme, "Kaze yo Tsutaete...", which later evolved into the character's main theme. Following this, however, was her first major project: Breath of Fire III, which she co-composed with Akari Kaida: the first of a handful of projects the two partook. Other projects Aoki was involved in include the console version of Pocket Fighter, Steel Battalion and Shadow of Rome.
