Nexus 4/ Shine is the 35th single released by L'arc-en-ciel, one of the key bands in the world of Japanese rock music.
Written by the the band's leader Tetsu, the two songs are representative of L'arc-en-ciel's brighter style (as opposed to the gothic rock of Drink it Down).
Both songs are carefully arranged such that each part, drums, bass, guitars and vocals compliment each other to bring out the liberating message of the songs. When Nexus 4 carries the power that that seems to cut the chains that drag you down to reality, Shine, the theme song of Seirei no Mamoribito brings the scenes depicted in the song to life through its lyrics.
