The only female in the Tetsumen Tou. She often butts heads with Asimov, Freud, Shouko (though not as frequently as with the other two), and Robby (one time). She uses her charms to get things the way she wants. She pilots the Venus robot. She has a crush on Koumei. Near the end of the series, she, along with Asimov Katoki, Orjin, Norman, and Hashnikov, were used as energy supplies by the Sigma computer and Sigma-Ken until they decided to stop using them and threw them away; it was only by the efforts of Kumano and Freud that they could be reached and helped in time. She faced Ken in Episode 27 with the Venus robot. Her name is a reference to Marilyn Monroe.
