The younger of the Hisakawa twins, Hayate dreamed of being an idol long before her decision to audition. Despite their different interests and personalities, she loves her older twin sister Nagi Hisakawa dearly, and together they form the unit miroir. However, Hayate initially disliked the idea of debuting with Nagi as a unit instead of individually. During her audition, Hayate stated that she wanted to become an idol so she could be told that everyone likes her.
