H-cup porn singer Takayama Kyoka, performing as HiBiKi, dreams of becoming a singer-songwriter and uses porn as her first step toward fame. For her second release, her agency offers what it calls a live event—but the concert is a lie designed to have her sing, then fuck a porn actor in front of a devoted male fan. Without being told beforehand, she is also made to have one-on-one sex with that fan, turning her ambition and performance into a staged publicity stunt.
