Sterling, aka Jingyi "Justin" Park, is a human that resides in Shortwave City, running around the streets and buildings as a graffiti artist and a freedom fighter. He and his little sister, Mingling "Quill" Park, work together in order to spread the word on how the Trivials are negatively impacting all parts of Ongaku. Yet, when things are starting to get worse, especially within the seven major cities, he and Dot come up with a plan to put a band together to utilize their music against the Trivials.

As a character, Sterling is very down to earth but has a strong desire to give the people of Ongaku the freedom of choice they deserve. Though he can occasionally come off as passive aggressive or intimidating to strangers, he is able to get along with pretty much anyone, as long as they aren't being jerks themselves. If they are, he definitely comes off as cold. He is not only the best friend to Dot, but is the boyfriend to Teddy Harmony, the group's guitarist.

In the band, he is not only responsible for playing the keytar and the keyboard, but he is also another lead vocalist. Much like Dot, I would prefer there to be a singing demo attached to the audition file. Though, of course, this isn't mandatory. Sterling's singing range is a tenor to baritone range.
