The Jumprope That Erases People (人を消すなわ跳び Hito o Kesu Nawatobi) is the ninth episode of Choudenshi Bioman. This episode is notable as the final on-screen footage of Yuki Yajima as Mika Koizumi (Yellow4) with Mayumi Tanaka dubbing in her lines. The next episode, while with Mika as Yellow4, will not feature any footage of Yajima outside archival footage even with her as the main focus in the story. In the Philippine Dub the title of the episode changed to "Doctor Man's Computer Menace".
