* HeyItsThatGuy: In the live-action adaptation, Takeru Sato ([[Series/KamenRiderDenO Ryotaro Nogami]]) is Koyuki, whereas Hiro Mizushima ([[Series/KamenRiderKabuto Souji Tendou]]) plays Ryusuke.
* HeyItsThatVoice: For one, Saku's English voice is provided by none other than JohnnyYongBosch, one of the most well-known everymen in internationalized anime.
** Not to mention that Koyuki himself is [[OuranHighSchoolHostClub Kaoru.]]
** The Philippine dub is said to be done by several popular rock stars in the country.
* BreakthroughHit: "Loser".
* SimilarlyNamedWorks: Narrowly avoided - "Broken Train", from his 1999 album ''Midnite Vultures'', had the WorkingTitle of "Out Of [[XtremeKoolLetterz Kontrol]]", but he made a different part of the refrain become the TitleDrop because Music/TheChemicalBrothers had released a single called "Out Of '''C'''ontrol" the same year. The change came late enough that early promo copies of ''Midnite Vultures'' still listed it as "Out Of Kontrol".
