“A song to connect with someone. "This scene which seems like magic will slowly become common place"” —Author's comment (Translated by Descent87)
"World Calling" is Jin's 11th published original work. It is not part of his Kagerou Project series. It was the theme song of VOICE FES 2012 hosted by NTT communications.
"World Calling" was later released on November 28, 2012 as a double single, together with Jin's next song, "LIVEDRIVE". A remix by TeddyLoid is featured on IA PROJECT's compilation album IA/02 -COLOR-.
The song entered the Hall of Fame within 24 hours after it was uploaded.
