Joji (2015–present)
Aside from the comedic music he created under the Pink Guy alias, Miller also created more serious and traditional music under another stage name, Joji, which became his primary focus in late 2017. Speaking about his transition from his YouTube career to his music career as Joji, Miller said to Billboard, "Now I get to do stuff that I want to hear." In the article by Billboard, he specified that "Joji" isn't a character like Filthy Frank and Pink Guy. "I guess that's the difference," he continues. "Joji's just me."
During his time growing up in Higashinada-ku, Kobe, Japan, Miller began to produce music and sing with friends as a side hobby and a way to pass the time. After relocating to New York City, United States, Miller expanded upon his music career by starting his Pink Guy persona, which paved the way for his Joji persona. Miller originally announced his Joji album on 3 May 2014 alongside the first Pink Guy album. However, Miller subtly cancelled the project until he began releasing music under the name PinkOmega. Miller released two songs as PinkOmega: "Dumplings" on 4 June 2015 and "wefllagn.ii 5" on 28 August 2015, both of which were later released on the Pink Guy album Pink Season, the latter being re-titled "We Fall Again".
Miller intended to keep the music made under Joji a secret from his fanbase, as it mainly wanted his comedic music. In late 2015, two singles were released, titled "Thom" and "You Suck Charlie"; both were released under a false alias, but it was quickly leaked that the user behind the account was Miller, which prompted him in January 2016 to publicly announce on Instagram that he was releasing a full-length commercial project titled Chloe Burbank: Volume 1. In the same post, he linked his SoundCloud account.
Miller began releasing music under 88rising in 2017; the songs "I Don't Wanna Waste My Time" (on 26 April), "Rain on Me" (on 19 July), and "Will He" (on 17 October). Miller was featured in the song "Nomadic" with the Chinese rap group Higher Brothers. Miller performed live as Joji for the first time on 18 May 2017 in Los Angeles.

Miller debuted Ballads 1 under the label 88rising on 26 October 2018, which quickly peaked on the Billboard Top R&B/Hip Hop Albums Chart.
