Intro. Nia Teppelin (ニア・テッペリン, Nia Tepperin?) is the disowned daughter of Lordgenome. She is also an artificial being created by the Antispiral and serves as the main antagonist's messenger in the third act. She is Simon’s primary love interest and eventually marries him in the final episode before fading away, though her love for him endures and binds them together. 40 years later, Simon (you) finally reunites with the love of his life after death.
