The near future. Iroha Sakayori, a 17-year-old high school student at a prestigious prep school in Tokyo, spends her days in an incredibly busy cycle of balancing part-time work and academics.

With Iroha producing the music and Kaguya singing as a Liver, the two slowly begin to bond. All while remaining unaware that an ominous shadow, intent on taking Kaguya back to the moon, is drawing near—
