cure beat (fake)
A false Precure created for Suite Precure in a very blurry version of post #1069213, leading viewers to assume that Nishijima Waon would become Cure Beat. These rumors were dismissed when Kurokawa Eren became Cure Beat. This fake Cure Beat's civilian name was Nishio Uta.
To differentiate the two Cure Beats, Uta has been given the fan name Cure Chord (キュアコード). If you see this as a Pixiv tag, it is referring to this fake Cure Beat, NOT to Waon cosplaying as Cure Beat.
