Agate
Agate is an Idol who stands out for a pretty specific reason—she's basically always there either to support Nick emotionally or handle her actual Idol duties. There's not much to her character beyond those two roles, which honestly works for the show because it keeps things moving. She doesn't have subplots or competing motivations the way other anime characters do. Her entire purpose is functional: she's either advancing Nick's development or doing what an Idol does.
