Michiru

Michiru is a sports-club instructor and the source of RX's lovesickness. At the opening credits of SD Riders RX was about to give her flowers but by mistake gave them to Bee Woman. In the beginning of the movie RX was explaining to ZX of have he fell in love with Michiru in a flashback (note others also have a crush on her too). When all the top sports players are kidnap and later we found out that Michiru is the best at tennis, Kamen Rider 1 ZX and RX went to protect her and make sure she is not kidnap by GranShocker but sadly she was kidnaped and brainwashed by spider man who tricked Black RX to retrieve her from GranShocker. Defying Rider 1 and ZX's advice, Black RX goes to save Michiru, only to find she's been brainwashed and ordered to kill him. Black RX is beaten senseless by Kumo and Michiru and is helpless to retaliate even with the help of Rider 1 and ZX who all three were forced to a courner until V3, X and Super-1 came to the rescue with Super-1 destroying Spider Man's control over Michiru. After the battle is over and V3 wakes Michiru up V3 instantly becomes smitten with her. And she felt the same to V3 as well. At the end V3 and Michiru ride off into the sunset, while Black RX is left behind to cry over his loss, which he quickly forgets after triumphantly burying the defeated General Jark in the sand.
