Sister's Noise

Sister's noise is the opening song for the season 2 of the Toaru Kagaku no Railgun animation show, Toaru Kagaku no Railgun S. It was released on May 8, 2013 as a single by fripSide. It is also included in Toaru Kagaku S Ep 24 as background music.

Sister's noise's video used the Sisters theme, portraying them as supporting characters and dancers that perform with the fripSide duet. fripSide made an appearance in the film as they stroll inside an industrial facility and observe the demolition of a laboratory where perhaps identical live beings were created. Despite the onslaught, the facility produces two further clones that resemble middle-aged siblings with a rounded physique.

The promotional film was produced in freezing weather (one evening's temperature was 2 degrees Celsius), prompting cast members to immediately put on coats and heavy gear after each scene was completed. Both Nanjo and Yaginuma believed that the dancers portraying the Sisters made the most significant contribution to the filming.
