Asuka Yayoi, Celonius 28

セロニアス28号

She serves as the "dark" counterpart to the other Yayoi Asuka. She was created to safeguard the "light" and Tetsuro Tanaka prior to their births. However, as time went on, Celonius 28 developed emotions, specifically feelings for Tanaka. Rather than protecting them both, she now wishes to destroy the "light" in order to possess Tetsuro exclusively.
