Blue is the personification of depression, lost in a world of faceless numbers. Her only friends are other personified mental disorders, but who exactly are they, and why are they here? And who is Red, the enigmatic person that appears as her male doppelganger? Something isn't right, and since Blue could care less about life, it's unlikely that she'll find out why any time soon.
