The main protagonist of Danganronpa/Zero and the Ultimate Analyst. She was diagnosed with a psychological disorder that causes her constant loss of short and long-term memories, forgetting things shortly after she learns them. Hence, she writes everything down in a notebook she carries with her at all times. She is in love with her neurologist, Yasuke Matsuda, whom she visits frequently for check-ups. It is eventually revealed that in actuality, Ryoko is nothing but a fake identity of Junko, the product of her experimentation with various memory-erasing techniques in preparation for the first mutual killing game. Upon learning the truth, Ryoko falls into despair and kills Yasuke, subsequently reassuming her true identity of Junko to spread despair once more.
