Haruka's story begins with her arrival in Sotenbori and her first steps towards becoming an idol. You'll be introduced to her manager, Mirei Park, and the basics of her idol training. Your first task is to attend a dance lesson, which serves as a tutorial for the rhythm game mechanics. Follow the on-screen prompts and hit the corresponding buttons in time with the music. Accuracy and timing are key to scoring well.
After the dance lesson, you'll have your first 'Audition Battle'. This is a direct competition against another idol. Perform well by hitting notes accurately and utilizing your 'Appeal' moves when prompted to gain a higher score and win the battle. Winning these battles is essential for progressing Haruka's story and increasing her fan base. You'll also have opportunities to explore Sotenbori, interact with fans, and participate in mini-games that boost her stats, such as karaoke or batting cages (though these are different for Haruka).
