Cheena was a main character in PlayStation 2 game, but she made a small appearance in the final episode of the anime and appears in the manga for several chapters. Like Ren, she is also a "Zero Numbers" and much younger than any of the DearS previously seen. She is known to Earthling scientists as "Sample B7", and has been charged with retrieving another escaped "Zero Numbers", only known as "Sample A2". During her very brief foray into the outside world she mistakes Ren for her target, and convinces Takeya to play at being a master to her. She decides to leave Earth with Ren, Takeya and the others when Io goes into outer space.
