R-20, aka Anise (Japanese: アニス Rōmaji: Anisu), was a small child with tremendous psychic power. However, when scared, her powers often shut down "meta-psychology" devices, such as Swordbreaker systems. In truth, she was a clone of Alicia Stargazer, and would sometimes express or experience her memories.
Kain Blueriver and Millie rescued her from Nightmare.
Anise only appears in the manga version of Lost Universe.
