WayV was set to embark on an eponymous global fanmeeting tour to support the album, with stops including Seoul, Manila, and Bangkok.

[6] The image showed only six silhouettes, confirming member Lucas's absence in the EP, making it their first album release as a sextet.

[11][12] The EP opens with the eponymous lead single "Phantom", a trap hip-hop based dance-pop song with string sounds and a chorus overlaid with Gregorian chants.

[6][15] The following song "Try My Luck" is a dance track that samples Mozart's "Requiem (Dies irae)", prefacing it with an air-raid siren.

[13] It features elements from Andrew Lloyd Webber's The Phantom of the Opera, such as candelabras, masks and broken chandeliers, as well as Game of Thrones-inspired sword-covered throne.

[6] Divyansha Dongre of Rolling Stone India described "Phantom" as a "fine addition" to WayV's discography that "perfectly accentuates the group's vocal tones" and features an "evocative" choreography.

[19] WayV performed "Phantom" along with their old songs "Love Talk" and "Take Off" at SM Entertainment's yearly online concert, SMCU Palace at Kwangya.

[21][22][23][24] On January 10, 2023, WayV announced that they would embark on an eponymous global fanmeeting tour, starting with two shows at Kyung Hee University's Grand Peace Palace in Seoul on February 11.
