Only My Railgun was released in 2009 by Japanese duo fripSide as the opening theme for A Certain Scientific Railgun, the spin-off centred on Misaka Mikoto and her electromagnetic railgun ability. The single became a major hit in Japan and helped define the series identity beyond the anime itself. Online, the opening riff spread through rhythm games, MAD videos and edit culture, where it still signals fast-paced anime action. Fans often group it with other instantly recognisable anime cues like Tuturu and Giorno's Theme in soundboards and compilations.

The high-energy opening theme from A Certain Scientific Railgun, known for its driving synth intro and iconic fripSide chorus used in anime edits and montages.
This clip captures the explosive opening of Only My Railgun, the signature track by fripSide built around fast electronic synths, pounding drums and a soaring female vocal hook. The sound hits instantly with bright, futuristic energy that feels like electricity charging up before a powerful attack. Listeners recognise the rising intensity and catchy chorus within seconds, even without visuals. It works as a burst of momentum and confidence, turning an ordinary moment into something dramatic and heroic. The polished J-pop and anime rock mix gives it a clean, urgent punch that stands out in short edits.
