Project DIVA is a rhythm game series, consisting of music made with the voice synthesizer program, Vocaloid, and its sister program Piapro Studio NT. Some songs available throughout the series contain some themes of sexual assault or other unhealthy relationship dynamics. Note that some songs may vary in availability or playability across the series, as it has had multiple installments and reboots since its original release in 2009. - "Adolescence" by SignalP features a relationship between two siblings that is heavily implied to be romantic/incestuous in nature. However, the lyrics are also intended to have multiple interpretations - for example, another interpretation of the the song is simply about how platonic affection between siblings is scrutinized once they reach teenhood. - "break;down" by hmtk: The song is about a woman who is in obsessive love with her coworker; there are undertones of stalking and possibly sexual harassment. - "Cantarella" by Kurousa-P: Loosely inspired by the story of Cesare and Lucrezia Borgia, it depicts a man who drugs a woman in order to assault her; they are also heavily implied to be siblings. - "Close and Open, Demons and The Dead" by Hachi: Often interpreted to be about sex workers of the Edo period, specifically about the assault and abuse sex workers faced. Another theory posits it's specifically about children conscripted into sex work in the same era. - "Don't MyList Me!" by Live-P: Included in the compilation song "Cool Medley: Cyber Rock Jam", but is not included as its own song. It features a meta-narrative about Rin becoming popular on Nicovideo, a Japanese video service where many Vocaloid users share their work. Throughout the song, Rin expresses feeling victimized and objectified by her fans who "MyList" her (a feature on Nicovideo that allows people to save songs to favorited playlists). - "Envy Catwalk" by Tohma: While the lyrics are not explicit and do not contain themes of sexual assault, it is heavily implied to be about a sex worker. - "Gothic and Loneliness" by Narushima Takashi: The song is about an immortal woman who has spent centuries in isolation; when a well-meaning knight comes to her castle, she begins to monopolize him, prevent him from leaving the castle, force-feed him aphrodisiacs, and force him into a relationship with her. - "Holy Lance Explosion Boy" by rerulili: While it does not contain themes of sexual assault, it has explicit lyrics about a teenage boy's reckless sexual behavior, which may be disturbing or uncomfortable for some players. - "magnet" by minato: While this song does not have themes of sexual assault, it depicts a relationship played by characters who are an adult and a minor, respectively. Many fans choose to interpret this as the minor being aged up or playing the role of an adult in the song. - "Rin-chan Now!" by OwataP: The song is about Miku and Luka showering Rin with affection and openly dreaming about affectionate and romantic scenarios with her, some of which have sexual connotations (like Luka making a comment about making sure Rin does not find pornographic content of herself). While it is intended to be lighthearted and humorous, the song does have mild themes of stalking, harassment and possibly unhealthy age gaps (as Luka is 20 and Rin is 14). - "RIP=RELEASE" by minato: The song is about a woman who engages in reckless sex with a man who does not reciprocate her feelings. She obsesses over him, possibly stalks him, and threatens to kill him. - "Secret Police" by BuriruP: While it does not contain themes of sexual assault, it is about an oppressive police state that spies on its citizens - many undercover police are also close family members or romantic partners of citizens being spied on. Some aspects of the song may be uncomfortable to some viewers. - "Two-Sided Lovers" (aka Two-Faced Lovers) by wowaka: While the lyrics are vague and up for interpretation, some theories are that it's about a woman addicted to love or sex, or that it's about a woman who falls in love with a man, but is quickly discarded by him once he's had sex with her. - "Your Diva" by BokuP: The song itself is a meta-narrative about Miku, as a program, learning to work and sing alongside her new producer. There is a brief joke about her producer making her sing perverted songs, which she immediately rebuffs and tells her producer to instead create lyrics from their heart.
