Burn Up Scramble

Synopsis

After a late night on the town in which Rio is repeatedly exploited by men trying to sell her things, she collapses back at her apartment. In the morning, Flying saucers appears over Tokyo, and release robots which go rampaging through the city, taking control of people including Yugi and the rest of the police force. Only the Warriors and the Commander seem unaffected. Maya and Lilica destroy many of the robots, but one saucer transforms into a giant robot. A gigantic Rio then appears, apparently enlarged by new police technology and engages the robot in a titanic struggle. During the battle, her clothes are ripped revealing her underwear, to her great embarrassment. However later she wakes up and realizes it was just a dream.
