Kanata's 3rd costume is officially named Work. Since evazion wants us to move away from nth costume qualifiers sooner, we've adapted "Work" for a few other costumes, specifically slightly more idoly ones, since "Idol" would be ambiguous with their proper idol uniforms.
I kinda enjoy that the Elden Ring fandom (semi)collectively agrees that Ranni, Rykard and Radahn were, at some point, a trio of siblings that were not afraid of being silly both together and with each other.
