Heart Knight - Quartet Night Taboo Night XXXX

Heart Knight from the Uta no Prince-sama: Quartet Night Taboo Night XXXX movie. Sung my Morikubo Showtaro as Reiji Kotobuki, Tatsuhisa Suzuki as Ranmaru Kurosaki, Aoi Shouta as Ai Mikaze, and Tomoaki Maeno as Camus. Unsure about who from Elements Garden composed/arranged/wrote the lyrics. Please tell me if you know and it will be added to this description.
