Premise: "Gekidou/Just Break the Limit!" (激動/Just Break the Limit!) is the tenth single by Japanese band Uverworld and was released on 11 June 2008 in CD and CD+DVD format. This is the band's first double-A single. "Gekidou" was used as the fourth opening theme for the anime "D.Gray-man" and "Just break the limit!" was used in a commercial for Pocari Sweat.
Hypothesis: Uverworld was paid for the use of "Just break the limit!" in a Pocari Sweat commercial.
