Builder and pilot of the The RX-零/RX-Zeromaru. Despite her cold exterior, she loves all things cute, especially SD Gundams and Beargguys.
Initially tagging along the Build Divers to spy on them per Tsukasa's orders, she eventually ends up befriending them and becoming part of the team.
Roughly two years before the start of the series, she was part of Chat Noir, a GBN Force bringing together fans of SD Gundams. However, following a streak of losses and a decrease in morale, it disbanded, leaving Ayame without a place to go and contributing to what would eventually become her severe trust issues.
Her true, real-life self bears some physical resemblance to her avatar, although younger. She also acts considerably less serious and confident.
