Due to the stress of the White Room, Ayanokouji developed dissociative identity disorder with multiple Ayanokoujis occupying the same body and mind. You have normal Ayanokouji, Hornikouji, and many more Ayanokouji with quirky and different personalities ready to take control of Ayanokouji's body. How will Ayanokouji survive ANHS with these multiple Ayanokouji taking control of his body at the worst moment possible?
