This is the second time since World Apart's B-side, "Uso to Wonderland" in 2006. This is the first time the band didn't use Yusuke Nakamura's artwork on their single, instead they just used the simple artwork with black color because Masafumi Gotoh imagined "Easter" as a grave and resurrection.^[2]

"Easter" is about Gotoh's ironic image about Tokyo that look like ghost town and from cultural point of view, it's just a vacant lot. The title taken from Christian festival and holiday, Easter and he hoped that there's right timing to bring us back to something once again, even if it's not festival.^[3]
