Some time after being fired from their idol agency, You (name changeable) stumbles upon a cute young girl with big, big dreams. She introduces herself as Cthulhu (aka Kuku), a Great Old One from the underwater ruins of R'lyeh. For many years, Kuku has whiled away her long, long life dreaming... But, during this time, her dedicated following has dwindled down to almost nothing! Determined to revitalize her cult and regain a brand new slew of worshippers, Kuku comes up with a masterful plan: namely, that she'll become an adorable idol and conquer the world through her singing, her dancing, and her charm! Work with Kuku as her producer to manage her schedule, raise her stats, and make decisions that will shape the trajectory of her career. Don't let her get too stressed, though: otherwise, the world might come to a watery end.
