She appears as a cameo in Title Theme & Ending - 7 GRAND DAD while "GO MY WAY!!" plays in the background, turning when she sees the idol Nozomi from the rival franchise Love Live! passing next to her.
For her birthday on April 3, 2017 (which happened during the Monochrome Pause) a series of rips featuring "GO MY WAY!!" but also several more obscure songs performed by her or related to her were uploaded by Wood Man (who was in charge on the channel at the time) though one day late. It started on her actual birthday date with GO MY WAY!! - THE iDOLM@STER (the first actual "GO MY WAY!!" rip on the channel) and ended two days later with GO MY WAY!! (M@STER Version) - THE iDOLM@STER, both rips being uploaded by the Voice as a way to officially end the pause.
Haruka was one of the Figments materialized into the real world by the Voice Inside Your Head in "Prologue", before being immediately taken by the Patrol-Bots. Her usefulness for the Voice as the singer of the GO MY WAY!! meme prevented her to share the cruel fate of most "Weeaboo Anime Bullshit" such as her fellow iDOLM@STER idols the Cinderella Girls or µ's' idols (minus Nozomi).
She eventually reappeared in "Loves the Ladies", the Voice masquerading her as Susie to calm Haltmann's fears, interpreting "Noble Haltmann". The trick did not work however, and Haltmann left the Voice's office furious, planning to order his employees to make Gadgetini Clone 2.0 in secret.She also appeared in the next episode, "An Acrimonious Assault", no longer in the Susie disguise. Here, she gives an encouraging speech to Nozomi before she could be defeated by Angry Joe.
