These are the openings of the three most recent Kamen Rider shows, Den-O, Kiva, and Decade.
While you can't understand the words, there is some english within the songs. Kiva has a "beating heart", "one & only" within the lyrics of the songs. (This seems way more common than you'd think in Japanese songs) In Kamen Rider Den-o, they have the word "Climax", which I don't want anyone to misinterpret as being dirty. I think they are using the word simply as a description about hight of action.
